Data through November, 2010 released today by Standard & Poor’s for its S&P/Case-Shiller Home Price Indices, the leading measure of U.S. home prices, show a deceleration in the annual growth rates in 17 of the 20 MSAs and the 10- and 20-City Composites compared to what was reported for October 2010.  The 10-City Composite was down 0.4 percent and the 20-City Composite fell 1.6 percent from their November, 2009 levels. Home prices fell in 19 of 20 MSAs and both Composites in November from their October levels. In November, only four MSAs – Los Angeles, San Diego, San Francisco and Washington, DC – showed year-over-year gains. The Composite indices remain above their spring 2009 lows; however, eight markets – Atlanta, Charlotte, Detroit, Las Vegas, Miami, Portland (OR), Seattle and Tampa – hit their lowest levels since home prices peaked in 2006 and 2007, meaning that average home prices in those markets have fallen even further than the lows set in the spring of 2009.
