How Accurate Is FHFA Home Price Data?

What FHFA HPI data can and cannot tell you about home price movement.

Last updated 2026-06-18

Accurate for a specific purpose

FHFA HPI® is useful for broad price movement over time, especially because it is a consistent public index with documented methodology.

Accuracy depends on using it for the right task: regional trend analysis, not a parcel-specific valuation.

Where accuracy breaks down

The index cannot adjust for a homeowner's renovation, deferred maintenance, views, floor plan, school boundary, or micro-neighborhood differences.

For a single property, the regional index should be treated as context and paired with current local data.
