Data through October 2010, released Tuesday 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 18 of the 20 MSAs and the 10- and 20-City Composites in October compared to what was reported for September 2010.  The 10-City Composite was up only 0.2 percent and the 20-City Composite fell 0.8 percent from their levels in October, 2009. Home prices decreased in all 20 MSAs and both Composites in October from their September levels. In October, only the 10-City Composite and four MSAs – Los Angeles, San Diego, San Francisco and Washington DC – showed year-over-year gains. While the composite housing prices are still above their spring 2009 lows, six markets – Atlanta, Charlotte, Miami, Portland (OR), Seattle and Tampa – hit their lowest levels since home prices started to  fall in 2006 and 2007, meaning that average home prices in those markets have fallen beyond the recent lows seen in most other markets in the spring of 2009. “There is no good news in October’s report.” says David M. Blitzer, Chairman of the Index Committee at Standard & Poor’s.
