CoStar expands homebuilding data reach with $800M Zonda deal
CoStar will gain access to “deep relationships across the homebuilding industry” as it bolsters its position in the new home market, CEO Andy Florance said.
CoStar Group is pushing deeper into residential real estate with an $800 million cash deal to acquire Zonda, a leading provider of homebuilding data, analytics and consumer-facing new home marketplaces.
This acquisition would give CoStar ownership of a business that serves more than 3,000 customers, including builders, developers, lenders and suppliers. In addition to its data and analytics products, Zonda provides a more direct path to homebuyers via NewHomeSource and Livabl.
The deal was announced May 29 and is expected to close in the second half of 2026, subject to regulatory approval and other customary closing conditions.
The bigger picture: The deal marks CoStar's latest effort to broaden its real estate information and marketplace ecosystem beyond its traditional strengths in commercial real estate and, more recently, residential search through Homes.com.
Zonda's platform provides data, software and analytics used throughout the homebuilding process, from land acquisition and development planning to sales forecasting and marketing. According to CoStar, Zonda generates most of its revenue through subscriptions and has a net customer retention rate of 104%.
What CoStar had to say: "Zonda has built an extraordinary business with deep relationships across the homebuilding industry and one of the most valuable proprietary datasets in new home real estate," CoStar Founder and CEO Andy Florance said in a statement.
CoStar said the acquisition will strengthen its position in the nearly $1 trillion U.S. new home construction market while creating opportunities to cross-sell products across its commercial, residential, multifamily, lending and analytics businesses.
Marketplace and technology opportunities: In addition to its data business, Zonda operates NewHomeSource and Livabl, online marketplaces focused exclusively on newly built homes in the United States and Canada. Builders use the platforms to market inventory, floor plans, virtual tours, pricing and incentives directly to prospective buyers.
As part of a broader push to improve how new homes are marketed and discovered online, CoStar also said it plans to combine Zonda's Envision visualization technology with the spatial-data platform from its 2025 acquisition of Matterport.
