As usual, foreclosure density varied by region last month, with just 5 states accounting for close to half of the nation’s repossessed homes.

Despite foreclosure filings surpassing 300,000 for the 18th straight month, RealtyTrac’s monthly foreclosure report shows some bright spots for housing.

Foreclosure filings rose 4 percent nationwide last month versus June, according to foreclosure-tracking firm RealtyTrac.com. For the 17th straight month, total filings topped 300,000. 6 states dominated activity levels.

According to foreclosure-tracking firm RealtyTrac.com, the number of foreclosure notices dropped 2 percent between April 2009 and April 2010. 2 percent may not seem like much, but it’s the first time in the history of the RealtyTrac report that the annual foreclosure rate has dropped.

According to foreclosure-tracking firm RealtyTrac, foreclosure filings topped 300,000 for the 12th straight month last month as 1 in every 418 U.S. homes received a foreclosure filing.

For as much as the foreclosure filing statistics can be astounding — over 300,000 homes were served last month alone — the prevalence of foreclosures depends on where you live.
