The worst U.S. housing crash since the Great Depression has led to a record number of foreclosures and shaved almost a third off property values. The S&P/Case-Shiller Index of 20 cities in August was 29 percent below its 2006 high, after rising for four consecutive months.

“We are bumping along the bottom of the housing market,” said James Lockhart, vice chairman of WL Ross & Co. and the former director of the Federal Housing Finance Agency. “There is the potential for another swing down.”

Sales of new U.S. homes fell 3.6 percent in September to an annual pace of 402,000, the Commerce Department said yesterday. That was lower than the 440,000 median forecast of 75 economists surveyed by Bloomberg News.
