The majority of the metropolitan statistical areas surveyed by Standard & Poor's for the S&P/Case-Shiller Home Price Indices reported declines from July 2010, suggesting buyers remain wary in a market riddled with negative economic news and foreclosures. The 20-city composite index dropped 4.1% over last year while the 10-city composite index fell 3.7% on an annual basis. Still, declines were less than the median forecast of 28 economists surveyed by Bloomberg News, which projected a 4.4% decline. The S&P/Case-Shiller Index said its 10 - and 20-city composite indexes increased in July over June, making it the fourth consecutive month-over-month jump in home prices. Still, values were little changed in July from June after seasonal adjustments. The only two markets to see positive rates of change in the 20-city composite over last year were Detroit  and Washington D.C., which rose 1.2% and 0.3%, respectively. The other 18 statistical areas surveyed by S&P experienced year-over-year declines. Minneapolis continued to fare the worst with its home price rate down 9.1% from last year. S&P said home prices retreated significantly enough in July to reach 2003 levels. Month-over-month, several markets experienced some price improvements. That list includes Boston, Charlotte, Chicago, Cleveland, Dallas, Denver, Detroit, Las Vegas, Miami, Minneapolis, Phoenix, Portland, Tampa, and Washington D.C. Write to Kerri Panchuk.
