ATTOM vs HelloData.ai
CRE Data & Property Intelligence APIs · Verified 2026-10-30 · No paid placement
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.
AI-powered multifamily comps, rent data, and market analytics platform
Aimed at multifamily investors, lenders, and analysts wanting AI-powered comps and market analytics without the enterprise overhead of legacy data providers — a newer entrant competing on speed and accessibility versus incumbents like CoStar or Yardi Matrix. Without published pricing, expect a sales conversation, and given it's a newer AI-native product, validate comp accuracy against a known market before trusting it for a live underwriting decision; it's multifamily-only, so no relevance for other asset classes.
