Massachusetts Attorney General Martha Coakley last week filed suit against Fannie Mae, Freddie Mac and their regulator, the Federal Housing Finance Agency, alleging that the GSEs are violating state law by failing to let non-profits buy foreclosed homes to sell them back to their former homeowners. In 2012, Massachusetts lawmakers passed An Act to Prevent Unnecessary and Unreasonable Foreclosures, which prohibits creditors from blocking or placing conditions on home sales to non-profits that intend to resell those properties back to their former owners. The AG’s complaint, filed in Suffolk Superior Court, says the GSEs failed to comply with the Bay State law by “blocking foreclosure buyback programs” designed to help residents keep their homes.
