RealtyTrac said Thursday that foreclosure filings, including default notices, auction sale notices and bank repossessions, were reported on 265,968 U.S. properties in September, a 12% decrease from the previous month but still up 21% from a year earlier. That data meant one in every 475 U.S. homes received some type of foreclosure notice last month. Foreclosure filings were reported on 765,558 U.S. properties during the third quarter, up more than 3% from the second quarter and 71% higher than the comparable period in 2007. RealtyTrac attributed much of the September decrease to changes in state laws that have temporarily slowed the pace at which lenders are moving forward with foreclosures. Nevada continued to have the nation's highest state foreclosure rate, registering an 11% increase from August. Florida's foreclosure rate rose 9% month over month. Just six states accounted for 60% of the third-quarter foreclosures, with California alone responsible for more than 27% of the total.
