CoStar Group is acquiring Zonda for $800 million in cash. The transaction is expected to close in the second half of 2026. 

Zonda serves more than 3,000 customers across the homebuilding ecosystem, including many of the largest residential builders, developers, suppliers and lenders in North America. The platform offers end-to-end solutions spanning land acquisition, development planning, homebuilding analytics, construction forecasting, community marketing and operational workflow management. It also operates NewHomeSource and Livabl, two online new home marketplaces in the United States and Canada. 

The data and software in Zonda are used to support underwriting, land strategy, capital allocation, development planning, forecasting and sales operations across the industry. 

“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,” said Andy Florance, founder and CEO of CoStar Group. “This acquisition extends CoStar Group’s leadership into a major new segment of the real estate industry and strengthens our ability to provide clients with comprehensive information solutions across every major real estate segment. We believe the combination will deliver deeper insights, workflow efficiencies and analytics to the homebuilding industry, while strengthening our core information offerings and significantly expanding our new home marketplace capabilities.”
