Real estate & property analytics · CoStar Group, Inc.
CoStar
Commercial real estate data and analytics business covering property listings, sales comps, lease data and market trends across the U.S. and beyond.
CoStar is fundamentally a data business built on a large research staff that continuously verifies commercial real estate information, property characteristics, ownership, lease comps, sale comps and space availability, across office, retail, industrial and multifamily markets. That data underpins CoStar Suite (the core research and analytics subscription for brokers, appraisers and investors) as well as consumer-facing marketplaces the company also owns, including Apartments.com and LoopNet, which both feed data back into the core dataset. Analysts use CoStar for market rent trend analysis, vacancy tracking, investment underwriting and competitive property research. Its closest analogue among these tools is Reonomy, though Reonomy leans toward ownership and off-market deal sourcing while CoStar's strength is verified leasing and sales comp data at scale.
