• ATTOM — nationwide, with deep historical chain-of-title going back 30+ years.
• DataTree (First American) — title-grade records with document images, best for complex ownership structures.

Are property insights platforms different from MLS?

Yes. MLS provides on-market listing data — properties that sellers have chosen to publicly market. Property insights platforms provide off-market property records, ownership history, equity position, liens, motivation signals (probate, foreclosure, vacancy), and skip-traced contact data — information that MLS does not surface and that is essential for off-market acquisition.

Which platform is best for real estate agents specifically?

Agents typically combine a property insights foundation (PropStream or CoreLogic for broad records), a motivation specialist (ProbateData for probate-driven listing opportunities), and an MLS-backed comp tool (Privy or local MLS access) for pricing accuracy.
