A new study says billions in government aid has failed to induce mortgage lenders to help homeowners facing foreclosure. According to the Federal Reserve Bank of Boston, only three percent of delinquent borrowers have had their loans restructured to lower monthly payments. The Obama administration has committed some $75 billion to mortgage lenders with the stated purpose of funding the restructuring loans. The study recommends that the money be given directly to the borrowers, instead of the lenders that have refused to help.
