I just want to keep my options open and know what my exit strategy would be if I do have to disposes before the ten years.FYI, since I did the original post, the broker sent me the lender defined YM sheet of the contract, and I will just go through and start crunching some possible scenarios, to get an idea of what kind of hit I would take...ALSO, I asked about Owner carrying a second if I a buyer assumes the first and he asked the lender who replied that it was very common for Fannie to do a supplemental second along with the assumption of the first, in this type of a scenario.I welcome any advice or opinions...please don't hold back, I have thick skin!
