With that, I would like to turn the call over to our Founder and CEO, Andy Florance. Thank you, Bill. Good evening, everyone, and thank you for joining us for CoStar Group's Fourth Quarter 2021 Earnings Call. Total revenue for the full year 2021 was $1.94 billion, which is a 17% year-over-year growth rate and above the high end of our guidance range given in late October. Fourth quarter revenue grew 14% year-over-year to $507 million, crossing through an important milestone of a $2 billion run rate for the first time. December 2021 was our best sales month ever. November, December, and January were three of our four strongest sales months ever. Net bookings of $67 million in the fourth quarter of 2021 were a new all-time high for us, up 37% year-over-year and 43% sequentially. Our trailing 12-month bookings in the fourth quarter was $217 million, growing 18% year-over-year. This is a significant acceleration from the trailing 12-month bookings growth of 6% year-over-year in the third quarter of 2021. Our profit performance in 2021 was also very strong. Adjusted EBITDA for the full year was $647 million, an increase of 17% and 27% above the high end of our guidance. 2021 was a solid year of growth and expansion for CoStar Group. We made significant investments in the CoStar product and our unified platform, overcame significant overheated apartment market challenges at Apartments.com, and we expanded our LoopNet and Ten-X businesses and established a solid foundation in the residential property sector. Our addressable market continues to grow every year, and our estimation now approaches $100 billion TAM globally. A couple of weeks ago, I ran across our TAM estimate from the year 2003, and that indicated global TAM of $1.6 billion. At that point, our total revenue was under $75 million. What a difference we've seen in 20 years as our revenue is now bigger than we estimated the total TAM global to be in 2003. It took us 16 years to go from zero to a $100 million revenue run rate in 2003, another 14 years to get to $1 billion annualized revenue in 2017, and only four years to surpass $2 billion revenue run rate. $5 billion, here we come. CoStar revenue was $723 million for the full year 2021, up 9%. CoStar's year-over-year revenue growth accelerated throughout 2021. We started the year with a 4% year-over-year growth in the first quarter of 2021, and it climbed until we exited at 13% in the fourth quarter. The strength is coming from a combination of record sales rep productivity, continued product upgrades, price escalations on subscription renewals, and strong renewal rates. Net bookings in the fourth quarter of 2021 grew 3x versus the fourth quarter of 2020 and matched our all-time high quarter in the third quarter of 2021. The CRE sales team is firing on all cylinders, delivering all-time high productivity in 2021, up almost 40% versus 2020. In 2021, we began upgrading the 18,000 accounts who are using subsets of CoStar's full product offering. This program is very popular with our customers, and by the end of January, we have converted about 5,700 accounts to the full global CoStar product. Our original estimate was that the upgrade program would contribute $30 million-$40 million in incremental revenue over a 12- 18 month period. The adoption rate, however, has been stronger than we expected, so we expanded the number of accounts to upgrade to include appraisers, owners, government agencies, and many others. This raises the number of upgradable accounts from 18,000- 21,000. As a result, we believe our original estimate that the upgrade opportunity would generate $30 million-$40 million is likely now to exceed $50 million. After having suspended price increases on CoStar subscription renewals during the pandemic, we restarted normal renewal rate increases in the third quarter of this year. Even at these higher price points from annual renewals and upgrades, clients continue to see strong value in the CoStar product, and we see that in multiple metrics. Our accelerating revenue growth, for example, is coming from a combination of both volume and price. We're finding that as we upgrade accounts, we're often increasing their number of users, and our user count is now over 170,000 subscribers. In addition, our renewal rate for CoStar remains very strong, 94% in the fourth quarter of 2021, well above the historic average of 92.4%. Our sales team has put a significant effort into strengthening our relationships with our clients. We see that effort pay off as our Net Promoter Score has been increasing, and as it does, so does our renewal rate. We believe that the launch of our new lender product on February eighth sets up another long-term growth driver for CoStar. Feedback while the product's in beta has been extremely positive. This is a truly revolutionary product that reverses our traditional flow of data in the industry. In the past, most lenders pulled data manually from multiple sources. CoStar for Lenders, in contrast, automatically connects their loan portfolio to CoStar's industry-leading research market analytics and our proprietary COMPASS Credit Default Model. The COMPASS Credit Default Model is the most mature in the industry, and this makes this solution unique as the best source for Portfolio Surveillance, Concentration Risk, Stress Testing, Current Expected Credit Loss, CECL, supporting Loan Originations, and underwriting. We're very excited about this new product. We have a dedicated and trained sales team that will be focused on upgrading CoStar's over 1,000 existing lender clients and engaging 6,000 other prospective lenders across the industry. With FASB's second-round effective date for CECL fast approaching in January 2023, we feel our solution is well-timed. There are literally thousands of institutions in the U.S. without an answer for CECL in place with this deadline approaching. Because CoStar offers lenders a range of solutions, it positions us favorably versus the competition. We continue to invest in long-term growth opportunities for CoStar, and that includes international expansion. To support our growth across Central Europe, we've begun hiring managers and teams of photographers for Spain, France, and Germany. These teams will be supporting both our CoStar and Marketplace assets as we begin the process of deepening our industry data in the largest European markets. Overall, I feel very good about our growth momentum for CoStar and expected revenue growth in 2022 to move above the historical 12%-14% growth range to around 15% year-over-year. I believe CoStar has a $10 billion global market opportunity in which we are less than 10% penetrated today. Apartments.com sales bookings rebounded sharply in the fourth quarter, climbing $20 million over the third quarter, driven by improved sales execution and price realization in the face of a continued ultra-low vacancy market. Apartments.com generated $675 million of revenue in 2021, up 13% year-over-year. Revenue growth in the fourth quarter was 6% in line with our guidance of mid-single digits growth. 2021 was a good year for Apartments.com franchise. Average monthly unique visitors in the fourth quarter of 2021 were 25 million, up 17% year-over-year. That is 2.5x RentPath average monthly unique visitors in the fourth quarter of 2021, 10x Apartment List, 17% higher than Zillow's rental network, and 11x Zumper. Leads delivered by Apartments.com grew 46% in 2021 and 27% in the fourth quarter. To keep this marketing momentum going in the first quarter of 2022, we will be releasing a new ad campaign featuring Goldblum in five new TV spots and eight new social video campaigns. When you see these new campaigns, I think you'll agree with me that it's some of the best work our team has produced to date. I look forward to having them out there. 2021 was a great year for our multifamily customers with record rent growth of 11.3% and a vacancy rate of only 4.6%, the lowest ever recorded. 2022 is expected to have rent growth of 6.5%, which would be the second best year on record with higher but still very low vacancy. The strong industry backdrop for apartment owners, combined with superior advertising value demonstrated through site traffic and leads, position Apartments.com to execute on our new pricing strategy. As a result, cost per lead has begun to improve, and we saw a significant improvement in net bookings in the fourth quarter of 2021 over the third quarter of 2021. Client losses have been minimal. The strong net bookings momentum, combined with modest improvements in the macro backdrop, gives us confidence that multifamily will be able to return to double-digit organic revenue growth in the second half of 2022. We estimate multifamily is a $7 billion revenue opportunity for us in the U.S., and we believe that Apartments.com is well-positioned to pursue that opportunity through unit penetration and demonstrated pricing power. 2021 was a very successful year for the LoopNet franchise. Full year revenue of $208 million in 2021 grew 15%. The Space For Dreams campaign delivered 2.2 billion media impressions in 2021. Unique visitors globally grew 22% year-over-year in the fourth quarter of 2021, and the LoopNet CRE network traffic was 10x the level of the network nearest competitor. Signature Ad growth continued to be very strong of 21% year over year in the fourth quarter of 2021. We continue to focus on expanding our sales distribution strength and are currently very close to our year-end 2021 sales headcount goal of 50 and continue to aggressively recruit salespeople for LoopNet. In 2022, we plan to continue the Space for Dreams campaign, supporting the industry and driving exposure for our advertisers. We expect LoopNet's revenue growth to continue in that 10% range for the first half of 2022 while we continue to build out a dedicated LoopNet sales team. I feel confident that we have never had stronger leadership, a better product roadmap, more innovative marketing, stronger technology, and better traffic than we have now. That is why I believe that LoopNet is well-positioned for a strong growth going forward. We remain excited that LoopNet has the industry-leading position in what we believe is in the early days of a $4 billion-$5 billion revenue opportunity. Ten-X had a strong year in 2021, the division's first full calendar year as part of CoStar Group. Ten-X sold $2.2 billion in gross merchandise value in 2021, up 47% year-over-year, and the company's best since 2016. In the fourth quarter of 2021, Ten-X sold $727 million in gross merchandise value, up 39% year-over-year, the company's best quarter since the fourth quarter of 2015. Full-year 2021 revenue of $57 million grew 7% year-over-year. While total sales in the platform is climbing, it does not translate as quickly to revenue because we've lowered our fees to drive more high-margin volume and to play an industry role at greater scale. We're investing in significant site and process automation to be able to process these higher volumes at high margins. Ten-X continues to sell more and close more. Trade rate, which is total assets sold as a percentage of the total assets brought to the platform, has improved from 54% in 2019 to 66% in 2020, and 73% in 2021. This has happened while we've been expanding the buyer base significantly. We estimate that Ten-X is a $4 billion revenue opportunity. To pursue that TAM, we're aggressively growing Ten-X's sales team currently up to 54 people. These new salespeople have been incredibly productive. In the first quarter of 2021, new sales reps didn't add any deals in the quarter. In the second quarter, they delivered 5% of the deals. In the third, they delivered 20%, and the fourth, they delivered almost a third of the deals. In addition, the research team in Richmond, which is in constant contact with brokers and principals who can benefit from Ten-X, has begun to contribute deals to the Ten-X pipeline. We've opened round one of the Battle of Bids 2022, a gamification of the Ten-X bidding process in which people can guess the price at which a real estate property will be sold with a chance to win up to $3 million in cash prizes. Our goal is to drive broad brand awareness and platform participation. We think we've created a really fun gamification of the CRE sales process that will bring the Ten-X story alive and engage tens of thousands of key prospects. 2021 was our first full year in the residential property sector. We generated $75 million of revenue. Homesnap revenue grew 52% year-over-year on a pro forma basis in 2021, driven by our larger direct sales force of 60 people. In the fourth quarter of 2021, Homesnap grew registered users by 12% year-over-year to 786,000 agents. Homesnap Pro+ paying subscribers grew 29% year-over-year to 68,000. Our acquisition of Homes.com in May 2021 was very popular with agents as we implemented a your listing, your lead product approach and doubled the site traffic year-over-year in the fourth quarter of 2021. That's right, we doubled the site traffic in the fourth quarter of 2021. Sounds familiar. Our strategy for transforming this massive TAM into revenue involves three phases, grow, monetize, and scale. By grow, I mean, first, we're going to focus on increasing traffic and engaging buyers and sellers in our platform. By monetize, I mean, we'll begin to introduce paid ads, which increase visibility for the clients and provide enhanced product features. By scale, I mean, moving into the phase where we stratify ad offerings to provide additional flexibility for agents and continue introducing more product features. Phase I, growing traffic is our focus today. We have a track record of success in building organic SEO in our marketplaces, including Apartments.com, LoopNet, Realla, BizBuySell, Belbex, and Lands of America, and more. How do we do it? By building easy-to-use technology with sound SEO structures and with features and content that people value. For Homes.com, that means building a system that breaks down the wall between real estate agents and home buyers. 93% of home buyers shop for their home on the internet, and 90% of home buyers use an agent to help find a home. Agents and buyers need to share information and feedback about home listings, but that's difficult today because they operate in two separate, essentially closed and disconnected systems. Agents use their local MLS, which buyers have limited or no access to. Buyers use various real estate portals, but those portals are generally trying to get those buyers to use the portal's small group of agents, so they're not effectively open buyer-agent collaboration tools across the industry. In fact, in essence, the structure was designed specifically to prevent transparency and collaboration. After watching hundreds of hours of interviews and focus groups, I can tell you that the thing that consumers and agents want that they're not getting and that what we can provide is collaboration. Homesnap is going to change that by enabling agents and buyers to share listings and feedback about those listings. By empowering agents with professional collaboration tools, we think it's possible to bring millions of buyers into our platform. The other takeaway from our interviews with consumers and agents is they want to be able to research the neighborhoods and parks that are important to them when they're considering a new home. We'll be creating powerful and professionally produced rich media and content of neighborhoods, parks, and condo buildings across the United States. The other thing that Homes.com will do is support your listing, your lead by enabling potential home buyers to easily contact the listing agent at no cost to that agent. We believe that sending these free leads to listing agents will increase the usage of Homes.com and Homesnap by all agents and provide a dramatically better user experience for buyers out there shopping. We expect phase I of the product will be ready to go at the end of 2022 with a full launch in the first quarter of 2023. That said, you won't need to wait until end of 2022 to see our residential strategy in action. You will see a microcosm of our residential strategy when we launch CitySnap in New York in July. In October, we announced a partnership with the Real Estate Board of New York to create the first ever consumer-facing search website and mobile app for New York City's residential listing service. Similar to Homes.com, CitySnap will connect potential buyers and renters with listing agents consistent with our 'your listing, your lead' philosophy and make collaboration possible through access to Homesnap's suite of tools. It will also feature promoted listings for residential real estate for the first time, similar to what we do with Apartments.com and many other real estate portals in other countries do. We believe that residential is a huge opportunity for CoStar Group, so large in fact that we believe our residential revenue will one day eclipse the revenue we generate in the commercial property sector. We estimate the US opportunity for residential is $72 billion. The global opportunity is $210 billion, not $200 billion, $210 billion, 3x the US opportunity. We believe that we can grow our residential revenue to $1 billion over the next 5-7 years as part of our new long-term revenue goal of $5 billion in revenue by the end of 2027. At that scale, we would expect our Adjusted EBITDA margins to be at or above our five year target of 40% based on the success of similar residential marketplace businesses around the world. In order to achieve this goal, we plan to increase our level investment in the residential business by approximately $200 million in 2022. The majority of this investment is funded by the significant cash generation of our existing business as we still expect to generate over $605 million in Adjusted EBITDA in 2022 net of that residential investment. I'm excited to make significant progress this year and believe we have a unique opportunity to add another $1 billion revenue platform + to our portfolio. In December, we announced plans to build a two-building, 750,000 sq ft corporate campus by the James River in Richmond, Virginia, to be completed by 2024. Richmond is a vibrant, growing, affordable city with a great quality of life and 10 colleges and universities in the area that are both our research partners and our talent pool feeder. At CoStar Group and in Richmond, we're proud to employ amazing people who create and provide the best products, information, analytics, and marketplaces that power the real estate industry. We strive to set the standard for accuracy and precision in everything we do because our clients rely on this data to conduct hundreds of billions of dollars in transactions. This type of exacting standard requires discipline, determination, commitment, and the people of CoStar Group take great pride in their ability to deliver at this level. We provide our people with world-class industry training, enable them to advance professionally and enjoy long, rewarding careers with CoStar Group. It does involve in measuring our performance and our work and having KPIs like any organization should have. Like any company, we have people who decide demands of our environment is not for them, and that's fine. For most who choose to leave, they're able to leverage the CoStar Group fundamental training and go on to enjoy productive careers in commercial real estate in other industries, or continue their education. The real estate industry attrition rate in 2021 was 32.8%, but our attrition was slightly higher at 36.6%. About 300 basis points or so. The key difference between CoStar Group and the rest of the industry is that we achieved a 99% employee vaccination rate, and our employees have returned to working safely back in the office. As you know, that's very rare. Our staff is more productive back in the office. Collaboration, innovation is stronger, and training is much more effective. We do have a tiny vocal minority of disgruntled former employees who do not want to return to work. But despite that, we would take the same responsible long view direction again. Now that we're back in the office, our attrition rate has returned to normal and over the past few months has in fact settled below the industry average. As hard as it was to return to the office, we're glad we've done it and feel for the companies that still have to cross that challenging bridge. We continue to believe that Richmond is a great center of excellence from which to grow our talent employee base that is supporting the real estate industry around the U.S. and across the world. Earlier today, we published our first sustainability report, which you can find in the Investor Relations section of the CoStar Group website. It's a very exciting piece. Thank you, Bill. At CoStar Group, we're committed to supporting ESG principles both inside and outside of our company. Inside CoStar Group, we have quietly been a leader in sustainability for decades, converting our fleet of nearly 200 research vehicles from gasoline to hybrid, and then eventually to electric. We select LEED certified or ENERGY STAR rated buildings for most of our 80+ offices, and reducing total annual data center energy consumption despite significant company growth. Outside CoStar Group, we help millions of consumers and real estate professionals achieve their sustainability goals. We pioneered creating transparency around building energy consumption when we were the first to widely publish building energy ratings. The CoStar Information Analytics product provides all subscribers with data on green rated buildings so they can identify locations that are ENERGY STAR, BREEAM, and LEED certified. In addition, we funded the Journal of Sustainable Real Estate to support academics who study the value of building and investing in sustainable real estate. My colleagues and I have authored academic articles analyzing financial benefits from building and leasing in sustainable buildings, and those papers have been recognized with Best Paper Awards. The United Nations estimates that buildings and construction account for 36% of global final energy use and 39% of energy-related carbon dioxide emissions. We believe CoStar Group is part of the solution to that problem, and we're focused on that. Our Apartments.com, Homes.com, LoopNet, and Lands marketplaces enable people all over the world to digitally visit properties for lease or sale without the environmental impact of physically driving to them. As you're aware, the economic recovery persists, but concerns about the virus, inflation, the prospect of raising interest rates weigh on the near-term outlook. Supply chain constraints and labor shortages are also prevalent, which is further challenging business operations, driving costs and prices higher. As a result, consumers are facing decades-high inflation, which is weighing on sentiment and potential spending. In an inflationary environment, real estate can be a safe haven. In hospitality, leisure demand continues to drive the US hotel recovery. Key metrics including Rooms Sold, Occupancy, ADR, and RevPAR are all either at or slightly above pre-pandemic levels, which is great news. Business travel, meanwhile, remains constrained as conferences are hampered by the latest variants of the coronavirus. Transaction volume ended the year at record levels, a signal of investors' long-term optimism for hospitality's recovery. In retail, strong consumer spending continues to support a resurgent retail environment. Foot traffic in physical locations has rebounded, especially in open-air shopping centers. Not surprising. Retailers have responded to the increase in consumer spending, and leasing volume is back to pre-pandemic levels. Notably, store openings outpace store closures, helping to drive net absorption to its highest level since 2017. As a result, rents grew by 2.8%, the strongest pace seen in over a decade. Headwinds for the sector do remain, including waning fiscal support and higher inflation, supply chain disruption, labor shortages, as well as an overhang of retail supply in certain segments. In industrial, that sector continues to benefit from the boom in consumer spending and the heightened need for enhanced supply chain networks. Expansions among e-commerce and big box logistics firms continue to fuel record leasing activity, which is up 60% from pre-pandemic levels. Despite a record amount of speculative supply under construction, there's little risk of overbuilding given such strong demand. Vacancy hit a record low of 4.2%, propelling rent growth to a record 8.6%. In the Office Sector, uncertainty is still the prevailing theme of the sector. After two straight quarters of improving leasing activity and slight positive net absorption, the national office market is starting to stabilize or showing signs of stabilization, and is likely in the early stages of recovery. However, significant headwinds and questions remain. The glut of sublet space remains a drag on the office market's recovery, though office users are increasingly turning to sublet leases for their space needs. It's still a Tenant Market, and while we've seen marginal increases in Occupancy and Face Rents, such an improvement masks the higher concessionary environment, which is weighing on owner revenue. LoopNet could help those owners get a great lease now. The national multifamily market is expected to normalize in 2022, but the sector remains at record levels in 2021 thanks to pent-up demand and regional shifts in migration in favor of Sun Belt markets. Record-setting demand is pushing vacancy rates to new lows. In turn, multifamily owners and managers are benefiting from record-setting rent growth. Developers are working to deliver new product to meet unrelenting demand, especially in the Southeast. Commercial real estate investment across the board is hitting record levels, led by unquenchable interest in multifamily and industrial assets. Retail and Office volume is making traction approaching pre-pandemic levels. Meanwhile, volume was up in virtually every major metropolitan area. Pricing is trending higher in all property types. Distressed sales remain a small portion of overall activity, underscoring the prevailing health of the CRE industry. At this point, I'm going to turn the call over to our brilliant Chief Financial Officer, Scott Wheeler. Excellent. Thank you, Andy. You're welcome. Glad I've achieved the brilliant category today. Hope you think so after I finish reading all these numbers. Certainly appreciate the comments and the great performance of the business in 2021. And obviously it sounds like there's no shortage of great opportunities ahead of us. Actually, I particularly enjoyed your throwback charts that you sent me from that 2020 sales conference when you had that itty-bitty TAM from 20 years ago of $1.6 billion. That had grown. In 2016 when I joined, it was $6 billion, we thought it was at that point. Now only five years later, we're talking about the $100 billion TAM sizes. I think that's pretty amazing. Anyway, enough of that giant global TAM mumbo jumbo. Let's talk some financials. Fourth quarter revenue and Adjusted EBITDA results were better than expected, both ahead of our consensus. $4 million ahead for revenue and $28 million beat on profit. That was a great way to end the year. Our fourth quarter Adjusted EBITDA margin was 38%, demonstrating the strong operating leverage inherent in our business. Our overall organic revenue growth rate was 11% for 2021, continuing a trend of 10 straight years of double-digit or greater organic revenue growth. CoStar revenue grew 13% in the fourth quarter and 9% for the full year of 2021, in line with our previous guidance. Our many product enhancements and our successful shift to a global CoStar platform has resulted in increased demand and improved pricing. We anticipate that this positive growth trend will continue and expect both first quarter and full year 2022 revenue growth of 15% for CoStar. Multifamily revenue grew 6% in the fourth quarter and 13% for the full year of 2021, also in line with the guidance we provided on our last call. As Andy mentioned, we saw Multifamily sales levels improve sequentially in the fourth quarter compared to the third quarter of 2021. Although we're not quite back yet to the level of sales we generated in the early part of 2021. Accordingly, we expect revenue growth rates to remain in the mid-single digits in the first half of 2022 for multifamily before improving to double-digit growth rates in the second half of 2022. Full year growth rates for revenue in Multifamily will still be around 8%-9% for the full year of 2022. LoopNet revenue grew 13% in the fourth quarter and 15% for the full year of 2021. Our CoStar sales team continues to sell an amazing amount of CoStar. That results in less sales of LoopNet at the lower end of our expectations as we build out our dedicated LoopNet sales team. Regardless, we'll still grow LoopNet revenue double digits even with a smaller sales team. For 2022, we expect LoopNet revenue growth in the low double digits, fluctuating around the 10%-11% range throughout the year. Admittedly, this is later in 2022. Information Services revenue grew 6% in the fourth quarter and 9% for the full year of 2021, in line with our guidance. We expect revenue growth in the mid- to high-single digits in the first half of 2022, improving to the low double digits in the second half of the year as contingent conditions improve in our hospitality industry. Overall, we expect 2022 revenue for information services to grow 8%-9% year over year. Our Residential Business delivered $21 million of revenue in the fourth quarter of 2021, slightly ahead of our guidance, with nearly all the revenue coming from Homesnap products as we complete the wind down of the legacy Homes.com revenue. Homesnap's pro forma revenue growth was more than 60% in the fourth quarter of 2021. For 2022, we expect residential revenue to be around $70 million, representing growth of approximately 15% year-over-year after adjusting for the runoff of Homes.com product revenues. As we move into 2022, we've identified specific residential products that are expected to be part of our long-term growth strategy. These products include the Homesnap Pro+ agent subscriptions, Homesnap listing ads, and Homesnap Pro+ Concierge lead management subscriptions, all of which in aggregate generated revenue of $55 million or 70% of the 2021 residential revenue. These continuing strategic products are expected to grow around 25% in 2022. By the end of the year, these products are expected to represent over 95% of the residential revenue. Other marketplace revenue was $35 million in the fourth quarter of 2021, well ahead of our guidance estimate of $32 million-$33 million on the strength of a big finish to the year for our Ten-X platform. In 2022, we expect continued strong growth from Ten-X, along with our Lands and Businesses for sale marketplaces, all of which are expected to grow around 20% for the year. In total, our other marketplace sector is expected to achieve revenue growth of 20% in 2022, which compares favorably to the 10% pro forma revenue growth rate we had in 2021. Net income was $93 million in the fourth quarter and $293 million for the full year of 2021. Our effective tax rate was 30% for the fourth quarter and 28% for the full year. Included in this effective tax rate for 2021 were one-time increases, primarily from international tax restructurings that will support our future growth. Without these restructurings, our effective tax rate would have been approximately 24% in the fourth quarter and for the full year. Let's cover a few performance metrics, starting with our net new sales bookings. We achieved $67 million of net new bookings in the fourth quarter and $217 million for the full year. Just like to say that again, but Andy covered all that cool stuff on our record sales level for the quarter, so I will move on. 217. 217. That's great. Our sales force totaled approximately 825 people at the end of the year, and they certainly had an exceptionally productive fourth quarter with that record sales result. The fourth quarter number is down approximately 25 compared to the third quarter of 2021 as a result of attrition in the Homes.com sales team that joined us in mid-2021. With increased confidence in our ability to train new sellers and visit our customers in person this year, our 2022 outlook includes expansion plans across all of our major sales teams. In January of 2022, we added over 35 new sellers to the ranks, so we're off to a strong start. Our contract renewal rate was 92% for both the fourth quarter and full year of 2021, unchanged from the third quarter of 2021. The current renewal rate is 200 basis point improvement over the fourth quarter of 2020, with both CoStar and LoopNet improving year-over-year. Renewal rate for the fourth quarter of 2021 for customers who have been subscribers for five years or longer was 97%, up 200 basis points from the fourth quarter of 2020 and consistent with the second and third quarters of this year. Subscription revenue on annual contracts was 77% for both the fourth quarter and the full year of 2021. Slightly below the fourth quarter of 2020, but slightly higher than the third quarter of this year. These modest fluctuations are a result of improvements in multifamily, along with increased Residential and LoopNet Signature Ad revenue, which tend to have shorter duration subscription contracts. Now, for our 2022 outlook. We expect 2022 revenue to range from $2.145 billion-$2.165 billion, an increase of approximately $210 million at the midpoint of the range, implying an annual growth rate 11%. Organic growth, excluding the revenue runoff from those legacy Homes.com products, is expected to be around 12%. Before I cover the 2022 Adjusted EBITDA outlook and investments, I'd like to highlight the exceptional results we continue to see in our commercial real estate-focused product areas, which includes CoStar, Multifamily, LoopNet, Information Services, and our other Marketplace Businesses. A few years back, at the end of 2018, we set ambitious growth goals to reach $3 billion in run rate revenue by the end of 2023 and 40% Adjusted EBITDA margins for that year. As a reminder, our $3 billion in run rate revenue goal was comprised of both organic revenue growth of 12%-14% per year, plus approximately $600 million-$700 million of new revenue from acquisitions. How have we performed against these goals? Well, with regards to the organic revenue growth, our performance is right on track in that 12%-14% revenue growth range for the years 2019 through our 2022 outlook. This highlights the strength and resiliency of our product portfolio, as we certainly did not anticipate the significant pandemic revenue slowdown in CoStar in 2020 or the current low vacancy market environment in multifamily that impacts the growth of that business. Regarding acquisition-related revenue, we added a little over $200 million in acquired revenue since 2018. In that time, we've certainly passed on deals that many times that amount, given what I consider to be unrealistic valuations and the difficulty of acquiring in a remote work environment. By my estimation, we could have spent around $4 billion-$6 billion of capital to acquire the level of revenue we had assumed in our targets. Rather than chase deals at those high prices, we elected to forego a number of opportunities and focus organically, which currently provides a much better return for our shareholders. With regards to our profit target of 40% Adjusted EBITDA in 2023, we now expect to achieve that goal one year ahead of schedule and are forecasting 40% Adjusted EBITDA for 2022 in the commercial real estate-focused product areas. As we've either accomplished or are on track with our current long-term goals, we believe it's time to establish new long-range goals, as the old goals don't include our recent expansion into the residential property markets or the great opportunity we see there. I will get to the new goals in just a minute. Our Adjusted EBITDA outlook for 2022 is comprised of two important components. One is the cash generation, and the second is deploying that capital for our growth investments. First, to cover cash generation, we expect to generate approximately $170 million of incremental Adjusted EBITDA in 2022 from the 12% organic revenue growth forecast. This added profit reflects approximately an 80% incremental margin drop through on new revenue. Pretty consistent with what we've done in the past. The second component is deploying capital towards our top growth initiatives. First, we plan to invest approximately $20 million in 2022 to expand our many sales forces as well as extend our international footprint in Central Europe. More significantly, as Andy discussed in his remarks, we plan to invest in content, technology, and marketing to support our Residential Expansion Strategy. Operating costs and investments for Residential, which totaled approximately $100 million in 2021, are expected to increase by around $200 million-$220 million to a range of $300 million-$320 million in 2022. A little over half of that increased investment is focused on proprietary content research with the remaining amount earmarked for marketing and software design and development. When we combine the cash generation of $170 million with the total investment range of $220 million-$240 million, the result is Adjusted EBITDA outlook for the year in the range of $565 million-$605 million. Our Adjusted EBITDA margin is expected to be approximately 20%, 27% at the midpoint of that range. First quarter 2022 Adjusted EBITDA is expected to be in a range of $155 million-$160 million, indicating a margin of 31% at the midpoint. As we move through 2022, we expect Adjusted EBITDA margins in the low 20% range during the second and third quarters of 2022 during the peak marketing and research season. Fourth quarter 2022 Adjusted EBITDA margin expected to improve to around 30%. I'll wrap up today with a summary of our new long-range targets that I mentioned earlier. These new targets incorporate the significant growth opportunity as well as the required investments for our success in residential market strategy. Our new long-range target is to achieve $5 billion in revenue and $2 billion in Adjusted EBITDA in the year 2027. Implicit in this target is an overall 17% compounded annual revenue growth rate. Our goal is to generate revenue from Residential products in the range of $700 million-$1 billion in 2027, which would replicate, if not improve upon, the success we've demonstrated with our Apartments.com investments. We believe the market size and opportunity in Residential is significantly larger than in Multifamily, and we would anticipate investment levels in Residential during the early years to increase before becoming profit accretive in a few years. Fortunately, we have a very large and profitable commercial product portfolio that we expect will generate over $800 million of Adjusted EBITDA in 2022 that will soon grow to over $1 billion per year. By the end of our long-term target horizon, I would expect Adjusted EBITDA margins from the commercial real estate-focused product areas of our business to approach 50%. With that, I'd like to add thanks to all of our amazing and hardworking CoStar colleagues for a fantastic 2021, and I certainly look forward to 2022 and what we can accomplish together in those years ahead. I'll now turn the call back over to Bill and our operator, as they're gonna lead us in a rousing rendition of Stump the Chumps. Bill, back to you. Thank you, Scott. Blue, would you please assemble the queue for Q&A? Analysts. Analysts, please limit yourself to one particularly insightful question. Thank you. Go ahead, Blue. Thank you. As a reminder, to ask a question, please press star one on your telephone. Your first question comes from the line of Sterling Auty from JPMorgan Chase & Company. Your line's now open. All right. The next question coming from analyst. Yeah. Thanks. Hi, guys. I was just curious, in terms of the investment in Residential, help us understand in 2022 how much of that's gonna go into sales and marketing, how much is gonna go into R&D, and how that mix will morph as you move towards that 2027 goal. Thank you. The majority of that investment in 2022 is content. It's in our Wheelhouse. It's one of our core strengths is collecting content for residential real estate to create a favorable environment for SEO and scaling our traffic to our site. A smaller part of that investment later in the year is towards marketing for the launch of the new site. There's also a significant component for software development and R&D. Do you want to add anything to that? Sure. Yeah. Sterling, the content portion is over half of the incremental investment, which is, you know, I gave a range of $200 million-$220 million. The other portion, which is a little less than half, is probably 60% marketing, but as Andy said, it's more later part of the year as we get ready for broader product rollouts. Then the rest is the technology development and software component, which may seem a little low, but as you know, we have a number of software teams in-house now that shift over and help us develop these new products, as will happen with our research teams as well. We'll expect these things to switch places as we go into 2023, as we'll have most of the content development piece behind us, then we'll shift more into marketing and product launch, I would expect in the next year or two. Your next question comes to the line of Ashish Sabadra from RBC Capital Markets. Your line is now open. Thanks for taking my question. Maybe a quick question around the Multifamily. Again, pretty strong bookings there. Discussion around mid-single digit growth in the first half and double digit in the back half. I was just wondering how much visibility do you have regarding the acceleration and growth in the back half? Thanks. Yeah, thanks for the question. You know, we definitely were encouraged when we saw in the fourth quarter that things came off of the, what we'll call the bottom in the third quarter, which as you know, when we run this subscription model out, that low third quarter will affect us in the first and second quarters of 2022. Just by the fact that you get past that and we move into the first half of 2022 into the stronger rental season, I think those natural growth numbers will advance in the second half. Now, right now, the success of the team in putting in our new list prices and executing on price increases is pretty much driving all the growth we saw in the fourth quarter. We're starting to see signs of increased, you know, upgrades and volume coming into this next year, and assuming that continues, then we'll see those growth rates lift in the second half. So it's still a ways away. We like to keep things a little bit close and cautious as we go into New Year's and let those first couple quarters play out, then we'll have a much better sight for you on the second half. Your next question comes to the line of George Tong from Goldman Sachs. Your line is now open. Hello, George. Hi. Thanks. Good afternoon. And then- The $300 million-$320 million in investment spend in residential is a significant step up. You mentioned the majority is going into content. Can you elaborate on what kinds of content you're investing in that you currently don't already have in residential that warrants this level of step up? Sure. It is $200 million incremental investment beyond the baseline of operating Homesnap and Homes that's currently in place. That content. The area where we're adding a lot of content, if you think about the home shopping experience, there are a number of things that are not about the specific home, but are about the place or in the case of a condominium building, about the community, not about the specific unit. Those are very cost-efficient places to collect valuable content, so neighborhoods, parks, schools, condos, and it creates good SEO drivers, and it creates a good shopper experience that we have tested with the markets and gotten very solid feedback on. One of the things we like about that investment is that while it's a lot of hard work and is aggressive, clearly it's in our Wheelhouse. We have visited millions and millions of buildings across many countries and been able to do that effectively and efficiently. The other thing that's good about that investment is it doesn't just benefit homes, it benefits apartments, it benefits LoopNet. It's a pretty broad initiative strengthening our content across the platform. We think in comparison to the scope of the TAM and the opportunity and the competitive advantage we perceive we can achieve, we feel it's a very reasonable investment. Was there a second part of that question? I don't think so, but I'll add a second part of an answer. How's that sound? Let's do that, Scott. Some of the content creation that we talk about in the early years, a number of that is, you know, one-time gathering of data and media that you've seen us do successfully, you know, across many different commercial platforms and markets. You'd expect that level of investment to drop back in the next year as you then focus more to the, you know, the marketing and the sales generation on the platforms. Again, considering the size of the market that we're talking about with Residential, that sort of an upfront investment is pretty small compared to the opportunity we see ahead. Your next question comes to the line of Peter Christiansen from Citi. Your line is now open. Good evening, guys. Thanks for the question. Andy, there's some helpful comments on M&A during the pandemic, and you know, it sounds like CoStar is now geared more organically going forward from here. As you think about the potential landscape for M&A going forward, particularly in residential, are there opportunities out there, do you believe, that could accelerate your scaling up on the resi side here? Thanks. Yes, definitely. We do have irons in the fire. We are looking at things. To scale and accelerate that. Obviously, as usual, we can't talk about anything until they're real. There's some significant things out there that, you know, we're really focusing as much as anything on strategic things that we feel will give us valuable content that will help us build the most heavily trafficked site over time. We're not looking to buy revenue per se. Your next question comes from the line of Andrew Jeffrey from Truist Securities. Your line is now open. Hey, guys. Pardon me. Thanks for taking the question. Andy, for those of us, at least for me, speaking for myself, might be a little bit, you know, denser, slower on the uptake. I think, you know, one of the things I'd love to hear you articulate in as concisely as you can, especially in the context of this big stepped up resi investment, what exactly is this strategy, right? I mean, I just wanna understand, you know, I realize it's a big TAM, right? We all get that. Who are you going up against? How do you plan to monetize? How do you plan to displace competitors, which I assume are companies like Zillow and Redfin and so forth? I mean, I think just really concisely, I think investors wanna know what you're spending all this money on and, you know, why. Not what you're spending on, what the return can be and how you get from point A to point B. In terms of what you're investing in, you know, at the core, we have gotten clear market research that says there's demand for collaboration. It's really simple. Today, agents and buyers really exist in two disconnected ecosystems, though they have to collaborate in the overwhelming majority of deals. We're building platforms where they can share content back and forth. When a buyer favorites a property, their agent can see it. When an agent must recommend a property, it goes into the favorite list of the client. Pretty straightforward. We've tested that with consumers all over the country and agents all over the country, gotten very positive feedback, along with a number of other software components and features. That's a big theme. Working with the industry rather than working to disintermediate the industry. That's something that worked well for us in the apartment industry. It's worked well for us in the LoopNet side of the business, CoStar, Lands of America. It's a proven model, and it's unique in the residential space. We're the only ones doing it, where you work with the industry rather than moving towards a disintermediation. In terms of SEO and content, we asked consumers what's really important to them, what they care about in a site, what they're looking for when they select a new home. You wouldn't be surprised to find out that for couples, you know, from the age of 25-40, schools are important. In a focus group, they all lean forward when you show them pictures of the neighborhood school. Leaning forward in a focus group is good. That's something we like to get people to do. We have tested and tested and tested. We found content that people care about and like that isn't currently offered. If you look at the current portals, they're all about taking content that other people have produced and repackaging it. You know, there's not a lot of original content being produced on those portals. There's opportunity to cost-effectively produce content that we believe appeals to consumers. In this case, I'm using something super simple like a picture of the local school or, you know, information about neighborhoods, something that we've done before and done quite successfully. You know, the neighborhood information in apartments helped us grow from being number seven in SEO to being number one in SEO. That kind of stuff we've done strategically. If you look back to when we launched Apartments.com, we did exactly this. We put a lot of people on producing content that gave us SEO advantage. It worked. It's tested. You know, we don't. I don't wanna write out a roadmap in plain English for everyone to hear, but I'm trying to give you some balance between them. This is. It's not, you know, it's not rocket science. It might be science, but it's not rocket science, and it's fairly straightforward. You know, if you look at what CoStar is good at, we're good at SEO, we're good at content development, we're good at taking pictures of millions and millions and millions of pictures, and we are good at collaborating with the industry and building successful models in collaboration. That's, you know, we're going to our strength. Your next question comes from the line of Ryan Tomasello. I'm sorry. I'll just add one more thing. How you monetize it? You know, pretty straightforward. It shouldn't mystify people. You monetize it just the way we monetize Apartments.com or LoopNet or Lands of America. People will pay for enhanced exposure to generate more leads or more activity on properties they're selling. That's the single biggest revenue opportunity in real estate. The second way you monetize it is by letting people market their agency services in a way that is not repugnant to the industry, in a way that is supportive of the industry instead of repugnant to the industry. That's pretty straightforward. You know, the question of how we compete against other people. CoStar Group has a track record of competing against other people effectively, and I think we'll rest on our record. Your next question comes from the line of Mayank Tandon from Needham. Your line is now open. Hey, good afternoon. This is actually Kyle Peterson on for Mayank. Thanks for taking the question. Just wanted to see if there was any, you know, notable, you know, seasonality that we should keep in mind for particularly the residential bucket, you know, given that, you know, there's some runoff from Homes.com, but then also a little bit of seasonality in the resi real estate industry and also some pretty strong organic growth in a lot of the core underlying businesses that you guys highlighted. Yeah, sure. We do see seasonality not too much different than what we saw when we first jumped into the apartment space. In apartments, there's a rental season, you know, in the spring and the summer months that would then cool off after kids went back to school. In the Residential side, you see a similar pattern where things will start off, let's say, at a moderate level to start the year, and then it picks up in the spring and the summer months, and then by the time you get to the end of the year, the fourth quarter is gonna be the weakest as far as you know, new engagement and involvement in the industry. We think second, third quarter is the biggest, fourth quarter is the lightest, and first quarter falls somewhere in between. We also expect that's where our investment focus will also follow that pattern when you talk about, you know, marketing and being able to collect valuable content during nicer months of the year than versus snowy, cold, wintry months of the year. You could actually look at the storage on our servers and you can tell the weather by how many terabits. Yeah We're putting into the system. That makes sense. Huh. You can actually see the weather in our storage. Your next question comes from the line of Ryan Tomasello from KBW. Your line is now open. Good evening. Thanks for taking the questions. I was hoping you can put a finer point on some of the drivers of the guidance for multifamily growth this year, specifically what you're contemplating for the mix of pricing increases versus new community count growth. As well as any, you know, potential color around the revenue mix among the different segments of the market, 100 + unit, mid-market, and the landlord independent landlord long tail. I know in the past you've provided growth rates around those different buckets, so it'd be helpful to understand how all of that is layering up into your outlook for this year. Thanks. Sure. In the early part of the year, we expect the revenue growth really from the list pricing and the pricing initiatives that we've implemented. The sales force is doing a great job of getting around to the customers. As we mentioned in the comments, we are not seeing people drop off the platform. We certainly see some of the fuller buildings in the market, like we commented I think last quarter, that might rotate off while other buildings rotate on within a customer's portfolio. You see a few less properties in total, but you definitely see people staying on the platform, and the pricing initiatives have been very successful. I expect all the growth in the first half of the year is pretty much from pricing. As you get more volumes into the spring and summer season, those volumes will carry over and you'll start to see, I think, more upgrades, fewer downgrades and a little more volume in the second half to get us back to that double-digit growth. We're still definitely focused on increasing penetration to new users in Institutional and the Multifamily, the Midmarket, and the Independent Owners. There is still significant penetration opportunity there. We plan to continue to grow that sales force to be able to basically touch more of those prospects, and we believe we can do that. While the pandemic was a slow time for being able to grow and more importantly, train sales forces, it's getting a lot easier. You know, we just finished up our first in-person sales conference in two years down in Miami, Florida. As the guy who spends the first four hours up on stage talking to the sales force, I will tell you without a question, we have a much bigger sales force today than we did two years ago. It is getting quite large. I'd say that group is very motivated and very positive right now and is producing at some of the highest levels they've produced at to wit the record quarter. Adding into that group, we think is gonna be possible to be able to go for more penetration. Scott's really forecasting more off of pricing. One thing about the pricing, you know, we are providing more and more value to our customers. As our traffic success grows, our leads grow. As our leads grow, our price per lead naturally goes down when we're pricing at the community level. There's lots of room to get recognition from our customers for the additional value we're providing them in increased lead flow. In essence, they're getting better and better values on lead flow, so their pricing per community might be going up. It's a share shift to us from possibly other marketing vehicles. Your next question comes from the line of Stephen Sheldon from William Blair. Your line's now open. Hey, thanks. I guess on the sales force side, it seems like some of the sales force build-outs have been a little slower than expected and are weighing on growth, especially looking at LoopNet. I guess at a high level, is there anything you need to do better to hire and retain sales resources across the company as we think about 2022 and the next few years? Yeah. You know, like the most important part of the equation is, it's great to have geese that lay golden eggs. What's even better is to have geese that lay geese that lay golden eggs. So those are recruiters. One of the things we're doing is we're looking within our own sales force for people that want to evolve their careers or into moving into the recruiting space. I think our training programs are pretty darn good at this point. Our onboarding is getting better. You know, our success rate as people come on board is getting better. You know, our sales force is getting pretty large. Again, you know, as you sit there and look at, you know, thousand people at our sales conference, it is growing. With LoopNet in particular, that is something just like Apartments.com has followed that same trajectory where initially Apartments.com was sold by the CoStar Group, and eventually we built our standalone sales force to sell apartments. LoopNet's in that same phase. We're having some success. As I look at the individual metrics of people going into LoopNet, the sales people going in, into that group, the standalone sales force, they're producing at much better numbers that we saw during the pandemic as we tried to onboard people. In fact, there's some real success stories in that group. You know, there's I think our number one producer, I believe, started with us just like two years ago. And then we have David Mele, who just joined us from Homes.com, who's an experienced operations executive now running the LoopNet group, which is good leadership. Mark Mathis, who actually started with CoStar many years ago, was a senior player at Realtor.com and ran their sales org, has been with Homes, is now running the LoopNet team. We're beginning to bulk the group up, and it's a process. It will be, you know, another two or three years before we have a robust, you know, several hundred-person large LoopNet sales team, but we will get there just like we did with apartments. Your next question comes from the line of John Campbell from Stephens. Your line is now open. Hey, guys. Thanks for taking my question. Just a quick one here. I mean, I think on the you know, the size of our Residential reinvestment cycle. I mean, I think that was a pretty common fear factor shared across the investor base. You know, the push and pull around that is, I think partly behind, you know, the stock on the 52-week low here. You know, your core business is seems to be in a great spot. You've got this big bet on resi kind of being more of an offensive move by you guys, and you guys do sound pretty convicted, and you've got a framework around eventually driving up those returns. I mean, obviously with things progressing as you guys expected, you've got kind of a stock that's kind of dislocated here. I'm sure you guys are anxiously waiting for this question, but you've got nearly $4 billion of cash on the balance sheet. It sounds like M&A is maybe a little bit less of a focus, you know, in favor of the core. Just give us your latest views on the buyback and how that might change if there's any further dislocations in the stock. Thanks. I think that's a great question, and I will turn that over to Scott Wheeler. Thank you, Andy. Yeah, we certainly saw a period here. Well, it's really only been a year. We just raised a bunch of that capital in mid-2020, so we're really only a year and a half since that money came on board. Certainly the period of high, you know, high multiples and valuations have weighed a little bit on the pace of our acquisitions. I wouldn't go so far as to say that we're not focused on acquisitions anymore, so we definitely are still very seriously focused on acquisitions. Our initial thesis when we brought in the capital is it's gonna take probably about five years for us to burn through that, as we do, you know, deals across the platform. I think we're still committed to that strategy right now. Obviously if this continues up for, you know, another year or two pace, we might have a different conversation. For now, that's still our direction, and we're focused on putting that money to work first in acquisitions, and then to the extent we need it on organic, we'd do that as well. Like you said, our organic commercial business is producing pretty significant cash flow now and that's very helpful when you look at our ability to invest in residential and still return. You know, we're still gonna do almost 600 million of EBITDA next year, even with as you put it, a big offensive investment. So we're pretty comfortable with the math and the balance of where we are. If you look at our past track record, we are an acquisitive company and, you know, we've acquired Homesnap recently. There are things out there, but we are value sensitive and I would imagine that over the course of the next three years, four years, we would probably use a lot of that capital in acquisitions. Your last question comes from the line of Jeff M euler from Baird. Your line is now open. Yeah, thanks for fitting me in. I appreciate the confidence in the strategy working out over the next several years, but just help investors understand, like what are the KPIs as you think about gate-keeping incremental spend through the three stages of your strategy. On, I guess monetization lagging, I understand the new product phase of it spooling up as products launch starting in early 2023. On the existing resi revenue, I think you said $70 million in 2022, and you had over like $20 million or around there of Homesnap revenue in Q4. You're already run-rate above that. If you could just help us understand why there's not better monetization on or better ramp on that existing monetization. Yeah, we're really going for the billions, not the hundreds of millions, is what it is. The most important role Homesnap plays to the company is growing the participating agent user base and getting deeper engagement with those users. You see us up in the 770,000 agents registered. You see us growing the number of folks paying for the premium version. We have multiple products we can sell over at Homesnap. We can sell sort of retargeting and Facebook ads and Instagram and Waze and all kinds of stuff. Those are the higher dollar value things, but they're less strategic. Like getting an agent to buy the, you know, $30, $40, $50 a month premium version of Homesnap is much more valuable to us in that they use and engage in the product more. The agents are the key to the supply side of the real estate industry, and we want to be the first place they go when they have a new listing or when they approach the market, or when they wanna distribute content to their customers. You know, we're going for the big win, not the second or third quarter. In terms of KPIs, if you go back to that three-step process of grow, monetize, and scale, grow is where we are and grow is where we will be into 2023. That is growing content, growing users, growing unique visitors, growing engagement and relevancy. We do not believe that we should pull the monetizing lever when you haven't scaled traffic. If you try to pull the monetizing lever before you've scaled traffic, you're gonna be setting price points well below what you could set a year or two out. We want to build engagement, grow that engagement, grow the unique visitors. For KPI, I would recommend that as we launch the new product, you look at our site traffic, our engagement. In the shorter term, you can look at the volume of content coming out of the site. You know, in a little bit, you can see that right now, Homes.com unique visitors doubled year-over-year. Keep doubling, after a while, it gets larger. The next thing you're gonna be looking for in 2023 you will continue to grow and monetize Homesnap. It's a great product that people like, and it's getting better. As you go into 2023, you'll be looking for new high margin products that will be available on Homes.com, whether it's marketing an agency in a responsible way or in an industry aligned way, or if it's marketing helping people market their actual properties. The first revenue you see coming in may be measured in tens of millions of dollars, but you can then understand the price points, and you can understand the penetration opportunity, and you can begin to paint out a 10-year picture. The scaling it to more meaningful levels is probably 24, and that's when we're beginning to you know, challenge some of our other product areas, and move towards that $1 billion revenue goal. We'll talk about the KPIs in each one of those three phases. I think you know, we are. It's obviously a huge industry. There's some solid competitors out there. It is not a get rich quick scheme. It's a work hard, build a plan, and have a multi-year vision of where you're going. We'll be able to talk about the KPIs at each of those three phases. There are no further questions at this time. I will now turn the call back over to Andy Florance, Founder and CEO. Well, thank you everybody for joining us for our fourth quarter 2021 earnings call. We're excited about the initiatives we've got going on here. We're very excited about the Residential initiative. Our core business is obviously showing great momentum. We're very proud of what we've accomplished, and I wanna congratulate our sales leaders, Mark Schwartz, Paige Forrest, Brandon Lewe, Tim Condon, David Gibson, Joe Valerio, and others, and their teams, who've just turned in our best bookings quarter ever with November, December, and January being three of our four strongest sales months ever. Look forward to them continuing to turn in a great result throughout 2022. We believe that the market conditions in residential sector, combined with our strength in our core business, makes this the right time to accelerate our investment in Residential and lay the foundation for growth that will enable us to reach our new five-year financial goals. With our expansion into the residential property sector, I believe that our investments will yield $5 billion in revenue for CoStar Group in 2027. I'm confident in our ability to scale our information and marketplace business to deliver attractive returns with Adjusted EBITDA margins at or above 40% when we achieve that $5 billion in revenue. We look forward to meeting with you again in our first quarter call on April 26 at the same time on the same channel. Until then, stay safe, and thank you very much for participating. Thank you, Bill. Thank you, Scott. Enjoyed doing this earnings call with you. Yeah. Thank you. It's great. Thank you. Good night, everyone. Ladies and gentlemen, this concludes today's conference call. Thank you for participating. You may now disconnect.
