ZIP 23878
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.
The federal house price index for ZIP 23878 (Southampton County, Virginia) runs from 2003 to 2021 and has risen +64.1% over that time, from a base of 100 to 164. FHFA's most recent value for this area is for 2021, so every span here ends in 2021.

Decade by decade
| Decade | Change | United States | |
|---|---|---|---|
| 2010s (2010–2020) | −1.6% | +35.5% | |
| 2020s so far (2020–2021) | +4.0% | +11.6% |
FHFA reports each index with a value of 100 in its base period, the first year the area has enough transactions (2003 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 2003 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. FHFA labels the ZIP-level indexes developmental: they are calibrated on appraisal values and sales prices for mortgages bought or guaranteed by Fannie Mae and Freddie Mac, and may be revised. The index tracks price changes for the same homes over time; it does not give a dollar value for any home.
