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.
