Home prices rise by 10.9% in March 2013 over the same month prior year, according to the S&P/Case/Shiller index of home prices tracking 20 U.S. cities. Prices increased by 1.2% for the 1st quarter of 2013. Part of the increase is because of the extent of the downturn, other reasons include the Fed's loose monetary policy and low mortgage rates of around 3%. The Shiller index also includes foreclosed properties which enlarges the increase in home prices when the share of foreclosed property sales fall. A separate index by Lender Processing Services shows a 7.6% increase in home prices for March. Prices are up in all 20 cities of the Shiller index for the first time. In San Francisco prices are up by 22.2%, in Phoenix by 22.5%. In the midwest Detroit prices are up 25%, as the auto industry rebounds strongly from a decade of decline.
