The full explanation
That is why it tells you how much prices rose or fell, not what a typical home costs. FHFA publishes it for the nation, states, metro areas, counties and other areas.
An example
Marta sees on her county's page that, according to the FHFA index, prices rose over the last few years. That tells her how prices changed, not what the home she wants will cost.
