Thank you for the feedback.
This confirms my initial suspicion that Wells Fargo was simply trying to limit their losses on the Short Sale. I acted on the suggestion to request a specific FHA/HUD guideline to reference regarding the 1% closing cost limitation and do not expect to have this answered as it most likely does not exist.
My instructions to the borrower and his agent were to push Wells Fargo as far as they can and be prepared to pay some of the closing costs out of pocket. The good news is that the agent is receiving a full 3% commission from Wells Fargo and he is willing to give up to 1% to the buyer for his closing costs. Considering that total closing costs + prepaids are 2.125% this will help the borrower tremendously.
I appreciate the additional information and advice.
Have a Great Day!
