The number of foreclosure filings reported in the U.S. last month jumped 93 percent from July of 2006 and rose 9 percent from June, the latest sign that homeowners are having trouble making payments and finding buyers during the national housing downturn.

There were 179,599 foreclosure filings reported during July, up from 92,845 during the same period a year ago, Irvine-based RealtyTrac Inc. said Tuesday. There were 164,644 foreclosure filings reported in June.

The national foreclosure rate in July was one filing for every 693 households, the company said.

"While 43 states experienced year-over-year increases in foreclosure activity, just five states _ California, Florida, Michigan, Ohio and Georgia _ accounted for more than half of the nation's total foreclosure filings," RealtyTrac Chief Executive James J. Saccacio said.
