Sale and Tax History
View all Redfin Property Data endpoints →The ownership timeline for a property: recorded sale events and tax/assessment history, keyed by propertyId/listingId. Where the sold search answers 'what did neighbors pay', this endpoint answers 'what happened to this exact home' — every recorded sale, price and assessment cycle. Plot appreciation curves, detect quick resales and ground a valuation in the subject property's own record.

Frequently asked questions
How do I get a US property's sale and tax records?
Call this endpoint with the propertyId/listingId pair from search or detail responses to get that property's recorded sale events and tax assessment history; for neighborhood-level closings use the sold search endpoints.
How far back do the records go?
Officially recorded sale and assessment events are returned; coverage depth varies by county, and gaps in early records are normal.
How is this different from sold search?
Sold search lists a batch of recent closings in an area; this endpoint returns one specified property's own full sale and tax timeline.
