Bush did sign the new legislation that makes the 1099 issue retro-active to Jan.2007. I believe it expires Dec 31 2009 or 2010. The Bill was signed in mid summer of 2007. It allows the homeowner to avoid the tax liabilty of the short sale, however I think you need to seperate the debt itself. The legisislation deal with taxes, not to say the lenders has to forgive the debt. Theres been situations where unsecure loan were put into place for debt balance as part of the short sale accepted by the lenders. Certainly the seller needs to get in writting that the bank will not pursue the debt balance thruough other means.
I question the issue with mult-family homes. Does it apply fully or just to the unit the home owner resides in. Similar to 1031 exchanges, the secord or third unit are income producing (generally)thus not the primary residence. I haven't got a clear answer on that.
So it applies to he tax liability not the loan debt-two seperate issues.
