Annual FHFA all-transactions index of single-family house prices in US counties, with 1990 equal to 100.

Developmental nominal index, not seasonally adjusted. Uses sale prices and refinance appraisals for mortgages purchased or guaranteed by Fannie Mae or Freddie Mac. Differs from purchase-only indexes. Missing estimates and unavailable base-year values remain absent. Historical estimates can be revised.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
