Meanwhile, home prices were up in May by the most in more than seven years, Standard & Poor's said Tuesday. The S&P/Case-Shiller Composite Home Price Index rose 12.2% from the previous year, the biggest 12-month increase since March 2006, following the 12.1% advance last month. On a monthly basis, the index climbed 1.0% in May after the 1.7% jump in April. The advance in home values is also boosting household finance, which may stimulate consumer spending, the largest component of the U.S. economy. On Monday the NAR published a report indicating a modest decline in pending home sales in June, with the corresponding index edging down 0.4% to 110.9 from a six-year high of 111.3 in May.
