Best commercial property owner data platforms for investors?

The leading commercial property owner data platforms for investors are Reonomy, PropertyRadar, ProspectNow, and CoStar. Each approaches commercial data differently, with Reonomy focused on entity resolution and ownership networks, CoStar focused on listing and market analytics, and PropertyRadar and ProspectNow combining commercial property data with broader search and outreach capabilities.

Commercial property data is harder to work with than residential because ownership is more frequently held by entities (LLCs, trusts, partnerships) rather than individuals. Resolving those entities to the actual decision-maker is the central challenge. PropertyRadar identifies property portfolios held by individuals, LLCs, companies, and trusts, and helps resolve the principal contact behind those entities where possible through its OwnerGraph feature. PropertyRadar supports commercial property subtypes in its filtering alongside residential, so users working both markets do not need separate platforms. The most important evaluation criteria for commercial property data are entity resolution depth, coverage of the target market's geography, and whether the platform includes distress and transaction data specific to commercial assets.
