ATTOM vs LightBox

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.

CRE data platform unifying parcel, tax, zoning, environmental (EDR), and listings data behind a persistent property ID and developer API

Buyer: data and engineering teams at brokerages, lenders, and PropTech companies building products on unified parcel-level data -- parcel, tax, zoning, environmental (EDR), and listings behind one persistent property ID. Strength: the breadth of data types unified under a single API is genuinely rare in this market. Caveat: enterprise pricing and API-first design mean it's overkill for an analyst who just needs an occasional zoning lookup -- that's a browse-the-website job, not an integration project.
