From the Federal Housing Finance Agency:
U.S. house prices rose in May, up 0.2 percent on a seasonally adjusted basis from the previous month, according to the Federal Housing Finance Agency monthly House Price Index. The previously reported 0.2 percent increase in April was revised upward to reflect a 0.3 percent increase.
The Federal Housing Finance Agency monthly House Price Index is calculated using home sales price information from mortgages sold to, or guaranteed by, Fannie Mae and Freddie Mac. From May 2015 to May 2016, house prices were up 5.6 percent.
For the nine census divisions, seasonally adjusted monthly price changes from April 2016 to May 2016 ranged from -1.3 percent in the New England division to +1.2 percent in the Mountain division. The 12-month changes were all positive, ranging from +3.4 percent in the Middle Atlantic division to +8.5 percent in the Mountain division.
Monthly index values and appreciation rate estimates for recent periods are provided in the table and graphs on the following pages. Complete historical downloadable data and House Price Index release dates are available on the House Price Index page.
