The Federal Housing Finance Agency holds the keys to the Fannie Mae/Freddie Mac loan limit kingdom, but its giving no clues or interviews as to where its headed on the issue. Meanwhile, pressure is mounting on the regulator to do nothing. As far as the mortgage industry is concerned, it knows a change is coming and hopes that when FHFA finally lowers the current high-cost limit of $625,500 the implementation date will come deep into the second quarter of 2014, or at the very least, March 31.
