About this estimate. This calculator is an independent tool that applies the publicly available FHFA House Price Index® (FHFA HPI®) to a value you enter. The FHFA HPI® is a 3-digit ZIP (regional) index that measures average price movement across a broad area - it is not specific to any individual property, and the result is not an appraisal, tax assessment, lender valuation, or guaranteed market value. zipappreciation.com is not affiliated with or endorsed by the FHFA.
