Fannie Mae and Freddie Mac — the perpetually insolvent, bailed-out GSEs that a whole host of BTFDers and a few disgruntled billionaires swear can become cash cows again if they are just allowed to escape the evil clutches of government — are now allowed to back home loans with down payments as low as 3%. The decision to lower the minimum from 5% to 3% came from the GSEs’ regulator FHFA and its Director, Melvin Watt.
