If its a short sale you are dealing with some lowly paid clerical worker who does not give a crap. There is no almighty “lender” making the decision there are a bunch of over worked underpaid grunts making these things happen and ultimately with luck it ends up on some middle managers desk to sign off on. None of these people really care about the details, all they care about is getting another file off there desk as long as its easy for them. If not they have a couple hundred more to work on. Give it a shot and see what happens but dont stand on ceremony. You are only fighting yourself and no one on the other side cares. If you like ti and the deal makes sense do it- if not dont. Do not make this personal its only business.
