As of Dec. 31, the Mortgage Bankers Association (MBA) reports the rate of mortgage borrowers past due one payment was at 8.22 percent, the lowest rate since the end of 2007.  This quarterly National Delinquency Survey also noted that homes repossessed by their banks hit the lowest rate since late 2008.  Michael Fratantoni, vice president of research and economics at the MBA, said due to recent tighter restrictions, most of the worst loans have already failed.  According to CNN Money.com, another good sign is that the percentage of seriously delinquent borrowers, those most likely to lose their homes, fell to 3.6 percent from 5.02 percent by March 2010.  This should mean fewer foreclosures in the future.
