ATTOM Data: 500M+ real estate/loan transactions, 2,690+ counties, 20-step Enterprise Data Management Program
Claim: ATTOM warehouses "more than 500 million real estate and loan transactions in over 2,690 counties", normalized via a 20-step Enterprise Data Management Program. Coverage: 99% of the U.S. population across 3,000+ counties; 70 billion+ rows; 9,000+ discrete attributes.

Confidence: Verified.
ATTOM customers (Roofstock, Offerpad, HomeFinder) build downstream products on the normalized public-records base. The persistent ATTOM ID across datasets is the entity-resolution moat — every property gets one canonical identifier whether the source spelled the address differently in two counties.
The ATTOM 20-step EDMP is the canonical demonstration that the moat is the pipeline, not the records. Every business in the US has equal legal access to the same county assessor data. ATTOM's value is what happens between download and queryable.
