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.
ZIP code 78631 is in Kimble County, Texas. FHFA's index for it begins in 2010; through 2024 it stands at 228, meaning prices in repeat sales of the same homes are up +128.2% since 2010. FHFA's most recent value for this area is for 2024, so every span here ends in 2024.
Over the ten years to 2024 the index rose +148.1%, about +9.5% a year: well above Texas (+99.2%) and well above the national index (+87.9%).

FHFA reports each index with a value of 100 in its base period, the first year the area has enough transactions (2010 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 2010 are not shown.
