CoStar vs Green Street
CRE Market Data & Research Platforms · Verified 2026-08-22 · No paid placement
The #1 commercial real estate information, analytics, and marketing company
The default data backbone for any institutional CRE shop that can afford it — broad but expensive, and pricing is deliberately opaque, so it's a negotiated enterprise sale, not self-serve.
CRE research, market data, and analytics covering REITs and private real estate
The standard reference for institutional investors, REIT analysts, and portfolio managers needing rigorous CRE research and market data across public and private real estate — Green Street's REIT-focused analytics have a strong, long-standing reputation in the space. Enterprise pricing puts it out of reach for individual investors or small sponsors, and its research-and-data orientation (rather than transactional tooling) means it complements, rather than replaces, deal-level underwriting software.
