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.
Oconee County, South Carolina ZIP 29664 has 18 years of index history. Since 2002 the FHFA index has moved from 100 to 135, a change of +35.0%. FHFA's most recent value for this area is for 2020, so every span here ends in 2020.
Over the ten years to 2020 the index rose +9.3%, about +0.9% a year: well below Oconee County (+25.4%), well below South Carolina (+29.6%) and well below the national index (+35.5%).
The index did not fall 5% or more from a peak between 2006 and 2012, which is unusual; small samples in a ZIP code can also mask movements.
Building activity is measured at county level: Oconee County authorised 737 housing units in the 12 months to August 2026, 8.8 per 1,000 residents, 95% of them single-family.

Decade by decade
| Decade | Change | United States | |
|---|---|---|---|
| 2010s (2010–2020) | +9.3% | +35.5% |
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.
