Sorry.......for some reason, I kept missing this thread when I go through the forum....

With the investor on your loan being FannieMae, that would explain alot of the runaround and misstatements by GMAC...........with the streamlined modification program that FannieMae has introduced, they are looking at the loans in their portfolio that are 90+ days in default at this time...........if this is the only property that you own and it is owner occupied..............you may want to try to go through NACA for the modification instead as they will negotiate a low fixed rate modification based on affordability if the criteria is met.............also with NACA, they don't require that you be in default to go through them and their services are free......we have seen modifications in the 4-6% range fixed for the life of the loan.............click on the link for the info..........
