Property data providers vs. public records: what's the difference?

Public records are the raw government filings (deeds, assessor records, court dockets, liens) stored at the county level, while property data providers collect those records, normalize them across jurisdictions, enhance them with third-party data and modeling, and deliver them through a searchable platform. Public records are the source. Providers are the processing and distribution layer.

The practical difference is accessibility and enrichment. Searching public records directly means visiting individual county recorder or assessor websites (or offices), each with different search tools, formats, and update schedules. A data provider normalizes those records across 3,000+ counties into a single searchable interface. Providers also add data that does not exist in public records: owner contact information, demographic estimates, automated valuations, equity calculations, and distress signals derived from combining multiple record types. PropertyRadar performs source comparisons, backtesting, and gap-filling to improve coverage and quality, using a multi-sourced, baked-off, backtested, and backfilled method. The trade-off is that providers introduce their own potential errors through matching and modeling, which is why important decisions should still be verified against the original county record.
