Trust me on this one.. I'm seeing too many folks getting burned right now by not talking to the right folks. A good real estate attorney is worth their weight in gold!
As both a broker and investor, I've seen this many times. In fact, I just used a strategy successfully to run interference with the bank and stop the acceleration demand on a house in 78249 that the owner could no longer afford to keep.
What did you do?
An REO or Shortsale is hard enough.....
Don't worry about the "forged", "stamped" or "robo" paperwork; you will not get anything from the Bank that is signed by a human being; that is normal.
Do you want the house, or not?
