Cook County Property Records by Address
Send a Cook County, Illinois street address and get one normalized record back — owner of record, parcel ID, the county's published assessed, market, land, and improvement values with their tax year, and recorded sale history where the county publishes it. Fields the county does not publish come back null with a field_notes entry naming the reason, and assessment rolls can lag a recent sale.
