If you are reasonably confident that a sale or refinance of the property is not feasible to pay off the loan at par, the master servicer will ask you to send them an «
imminent default letter,» explaining the situation and letting them know that payment in full at maturity is unlikely.
Most of the time, you just have to «push back» on them and point out that you are in
imminent danger of
default and prove it with your hardship
letter and income documentation.
