CoStar Group is making another major push into residential real estate data, announcing an agreement to acquire housing market intelligence firm Zonda for $800 million in cash.
The transaction, which is expected to close in the second half of the year pending regulatory approval, marks one of CoStar's most significant investments yet in the residential property sector.
Historically known for its dominance in commercial real estate data and listings, CoStar has spent the past several years expanding its footprint in housing-related platforms and information services. The acquisition of Zonda strengthens that strategy by adding a leading provider of residential construction, homebuilder, and new-home sales data to CoStar's portfolio.
" This acquisition extends CoStar Group's leadership into a major new segment of the real estate industry," CoStar founder and CEO Andy Florance said in a statement.
Strengthening Residential Market Coverage
Zonda is widely recognized for its data and analytics products serving homebuilders, developers, lenders, and housing industry professionals. The company has also expanded through acquisitions in recent years, including the purchase of Builders Digital Experience in 2024, which brought NewHomeSource.com and home design platform Envision under its umbrella.
The acquisition provides CoStar with deeper visibility into the new-home construction market, complementing its existing residential assets such as Homes.com.
CoStar acquired Homes.com in 2021 and has since invested heavily in growing the platform as it competes with established residential real estate portals.
Part of a Larger Growth Strategy
The Zonda deal continues CoStar's long-running acquisition strategy, which has included major purchases such as LoopNet, Apartments.com, and hotel data provider STR. The company has increasingly sought to build a comprehensive ecosystem of real estate data, analytics, and marketplace services across multiple property sectors.
Industry observers view the acquisition as a move to strengthen CoStar's position in a housing market where access to high-quality construction and sales data is becoming increasingly valuable for investors, developers, and lenders navigating changing market conditions.
Regulatory Scrutiny Remains a Factor
The transaction comes as CoStar faces ongoing antitrust scrutiny and legal challenges related to its market position in commercial real estate listings.
Recent lawsuits have alleged that the company holds a dominant share of the online commercial real estate listings market and has used that position to limit competition. CoStar has also faced regulatory opposition to previous acquisition attempts, including the unsuccessful 2020 effort to acquire RentPath.
While there is no indication that regulators will oppose the Zonda acquisition, the deal is expected to attract attention given CoStar's growing influence across multiple segments of the real estate data industry.
Industry Impact
For real estate professionals, the acquisition signals continued consolidation within the property technology and data sector. By combining CoStar's extensive real estate information platform with Zonda's residential construction and homebuilder intelligence, the transaction could create one of the industry's most comprehensive real estate data ecosystems spanning both commercial and residential markets.
As competition intensifies among property data providers, the deal underscores the increasing importance of proprietary housing data in shaping investment, development, and market decision-making.
