U.S. house prices rose in August, up 0.3 percent on a seasonally adjusted basis from the previous month, according to the Federal Housing Finance Agency (FHFA) monthly House Price Index (HPI). The previously reported 0.6 percent increase in July was revised downward to reflect a 0.5 percent increase.

The FHFA HPI is calculated using home sales price information from mortgages sold to, or guaranteed by, Fannie Mae and Freddie Mac. From August 2014 to August 2015, house prices were up 5.5 percent. The U.S. index is 0.9 percent below its March 2007 peak and is roughly the same as the December 2006 index level.

For the nine census divisions, seasonally adjusted monthly price changes from July 2015 to August 2015 ranged from -0.4 percent in the East North Central and Middle Atlantic divisions to +0.8 percent in the East South Central division. The 12-month changes were all positive, ranging from +2.2 percent in the Middle Atlantic division to +8.3 percent in the Mountain division.
