Who Profits From Short Sales
For home sellers who owe the lender more than their home is worth, it's not as bleak as it might sound. Negotiating a short sale with the lender could be the solution.
This means the seller or the seller's agent sells the home to a buyer at market, or slightly below market value, and the lender agrees to accept the proceeds as payment in full on the mortgage, even though the sales price is less than the existing encumbrances.
The downside is lenders are not required to negotiate discounted payoffs, and there is no guarantee your lender will let you do a short sale.
