[Update 2: Removes reference to electronic dispute for separate article post] Bank of America (BAC) pushed its total number of permanent modifications under the Home Affordable Modification Program (HAMP) to roughly 70,000 in May, up from 56,400 in April. BofA reported more than 630,000 modifications through all of its programs since January 2008. The Treasury Department launched HAMP in March 2009 to provide incentives to servicers for the modification of loans on the verge of foreclosure. Borrowers must make three monthly payments under a trial modification and provide all financial documents to the servicer before it becomes permanent. In April, servicers reported more than 300,000 permanent modifications under HAMP. Earlier in June, BofA began reducing principal for some qualifying underwater borrowers as part of the modification process. “Bank of America continued to make significant progress in converting HAMP trial modifications to completed modifications last month,” said Rebecca Mairone, default servicing executive for Bank of America Home Loans.
