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.

California, Florida, Arizona and Georgia accounted for more than half of all bank repossessions in March 2010. It’s a disproportionate distribution of foreclosures. Together, the 4 states represent just 23 percent of the overall U.S. population.

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.
