Compared with a month earlier, 14 cities showed price gains. The price figures aren’t adjusted for seasonal effects, so economists prefer to focus on year-over-year changes. Adjusted for seasonal changes, the index fell 0.2 percent in May, the smallest monthly decline since February 2007. If you’re looking for a bottom, there’s a lot of good stuff here.

The report buttresses other measures that have shown a deceleration in price declines. The Federal Housing Finance Agency said last week that its purchase-only price index was down 5.6% in May from a year earlier, the smallest annual drop in 10 months. The FHFA index is a national measure that tracks houses bought with mortgages purchased by Fannie Mae or Freddie Mac and excludes many of the foreclosure sales and properties bought with non-conventional mortgages. In addition to being limited to 20 areas, the S&P/Case-Shiller report also includes distressed properties and those bought with non-conventional loans such as jumbo mortgages.
