Questions this answers
6 · best fit firstRentCast returns yearly taxAssessments entries with total value, land, and improvements for a buyer-selected address, together with stable property/assessor identifiers. It pins component values and assessment year, but the cited schema does not define valuation basis, assessing-jurisdiction provenance, currency, release/index-through date, or query timestamp.
RentCast's address-keyed property record returns dated sale-history entries with date and price plus current owner details and mailing address. It does not document deed instrument/type, grantor/grantee roles, execution versus recording date, consideration basis, corrections/rescissions, source index-through date, or query timestamp.
For a buyer-selected U.S. address or coordinates, RentCast’s standing Rent Estimate endpoint returns nearby comparable rental listings with asking rent, property type/dimensions, listed/removed/last-seen dates, days on market, distance, and correlation. It supports residential and multifamily asking-rent comparables, not achieved commercial lease rents.
The address-selected property-record response includes owner and mailing-address evidence with property/assessor identity; it is not a title opinion.
For a buyer-selected U.S. address, RentCast’s documented property record emits ownerOccupied. This supplies owner-occupancy status only, not commercial use, tenancy, or loss-date operations, and must carry retrieval/source vintage.
For a buyer-selected address, the documented sale-listing endpoint supplies listed price, most recent listing date, and days on market for active or inactive sale listings; rental listings and complete over-time episode history are not claimed.
