FHFA notes: The FHFA HPI is a broad measure of the movement of single-family house prices. The FHFA HPI is a weighted, repeat-sales index, meaning that it measures average price changes in repeat sales or refinancings on the same properties. FHFA describes its ZIP code indexes as developmental: they may be revised as new data arrive or methods change, and the index does not give a dollar value for any home.

Every column uses FHFA's annual all-transactions index family and the same start and end years, so the figures are directly comparable. A dash means the level has no index for that span.

FHFA reports each index with a value of 100 in its base period, the first year the area has enough transactions (2002 here). A decade's change is the index at the end of the decade divided by the index at the start, so it does not depend on the base year; the United States column covers the same years. Decades before 2002 are not shown.

Where does the index for this ZIP come from?

From the Federal Housing Finance Agency's annual five-digit ZIP code house price index (all-transactions), last updated March 31, 2026.

The index tracks price changes for the same homes over time; it does not give a dollar value for any home.
