ATTOM vs First American Data & Analytics (DataTree)

Nationwide property data API — 160M+ US properties, ownership, sales, valuation, hazard data

Built for proptech companies, lenders, and data-hungry underwriting teams that need bulk API access to property, ownership, sales, and hazard data across the full 160M+ US property universe — this is infrastructure, not an end-user tool. Strong coverage breadth is the draw. It's enterprise-priced and requires engineering resources to integrate meaningfully, so a small brokerage or single-fund acquisitions team looking for a point-and-click comp tool should look elsewhere; ATTOM is for teams building on top of the data, not browsing it.

Parcel, ownership, HOA, lien, and mortgage/foreclosure data via DataTree, delivered by API and bulk licensing

Built for lenders, title companies, and data-driven acquisition teams needing parcel, ownership, HOA, lien, and foreclosure data via API or bulk license — DataTree's specific strength is in title-adjacent and distressed-property data that generalist property-data APIs cover less deeply. Enterprise pricing and a data-infrastructure delivery model (not a browsable app) mean this is for teams with engineering resources to integrate it, not for a small acquisitions team wanting quick lookups.
