HI Bill
I have been successful at getting a substantial discount from Wells Fargo (and other big name banks) BUT only when it was a short sale situation with the loan in default.
Usually the bank only services the loan but the note is actually held by a hedge fund on wall street somewhere. So, a discount has to go up the ladder to get approved. If the loan is in default, ask to speak with their loss mitigation department.
Here’s the number to call — https://www.wellsfargo.com/mortgage/manage-account/payment-help/short-sale/
If the loan is not in default, I think you’ll have a hard time getting a discount unless you can show that the value of the property has dropped a lot compared to the mortgage balance.
With short sales, they send out their own appraiser to evaluate the condition of the property. And the seller/borrower has to prove a hard ship on why they could not make their payments. To make it even more complicated, the seller cannot get more than $1000 in cash for moving expenses ( the bank does not want to take a hit with the defaulted seller gaining a windfall profit).
I doubt that you can get anyone to agree to walk the mortgage on an institutional loan.
Let us know how it goes.
