Just one in four of the 2.7 million homeowners who sought to participate in the Obama administration’s signature mortgage assistance program have succeeded in getting their monthly payments reduced. The rest failed to qualify for the program or were disqualified after they were initially accepted into the program, according to an analysis by the Wall Street Journal of data on applicants to the program newly released by the Treasury Department. In all, about 680,000 homeowners who applied for the Home Affordable Modification Program, or HAMP, had received permanent modifications of their loans and were making timely payments or were still in the trial phase as of December.
