In both short sales and foreclosure, the decision is made by your mortgage lender. The most important aspects to getting a lender to agree to a short sale, and saving you the more damaging credit implications of a foreclosure, is to prove that you have no other way to pay the mortgage and that the amount received from a short sale is the fair price of the market. Lenders who believe they can receive more by taking possession of the home in a foreclosure and selling it themselves will not agree to a short sale.
