The FHFA monthly index is calculated using purchase prices of houses backing mortgages that have been sold to or guaranteed by Fannie Mae or Freddie Mac. For the nine Census Divisions, seasonally adjusted monthly price changes from March to April ranged from -1.3 percent in the Mountain Division to +2.2 percent in the New England Division.
Monthly index values and appreciation rate estimates for recent periods are provided in the table and graphs on the following pages. Click here for complete historical data. FHFA has corrected some data in the quarterly HPI released May 25, 2011. The quarterly, fourquarter, and five-year price change estimates for Nebraska, Massachusetts, and Montana have been modified. The underlying index values for those states were correct, but the reported price changes were not accurate. The corrected numbers are now reflected in the tables and graphs in the revised news release and elsewhere on the FHFA website.
