WASHINGTON (MarketWatch) -- U.S. house prices rose a seasonally adjusted 0.2% in July, according to the Federal Housing Finance Agency's monthly house price index based on Fannie Mae or Freddie Mac mortgages. June's gain was revised to a 0.6% gain from a previously reported 0.7% increase. Compared to July 2011, FHFA reports prices are up 3.7%. Earlier, S&P reported the Case-Shiller 20-city composite index rose 1.6% in July, or a 0.4% gain after seasonal adjustment. The Case-Shiller index is constructed differently and also includes three months rather than one months of transactions as the FHFA index does.
