Home Prices in 20 U.S. Cities Declined 16.3% in July

The S&P/Case-Shiller home-price index dropped 16.3 percent from a year earlier, more than forecast, after a 15.9 percent decline in June. The gauge has fallen every month since January 2007, and year-over-year records began in 2001.

The housing slump is at the center of the meltdown in financial markets as declining demand pushes down property values and causes foreclosures to mount. Banks will probably stiffen lending rules even more in coming months to limit losses, indicating residential real estate will keep contracting and consumer spending will continue to falter.

(...) Home prices decreased 0.9 percent in July from the prior month after declining 0.5 percent in June, the report showed. The figures aren't adjusted for seasonal effects so economists prefer to focus on year-over-year changes instead of month-to-month.
