To
prequalify yourself for a "Short Sale" please do some research.
1. Find comparable homes sold in your
neighbourhood recently.
Make
sure those homes were sold for less than your mortgage ballance. Don't
forget to include in your calculations 5%-6% real estate commission and
approx. 2% closing costs.
2.
Look into "Foreclosure Law"
in your state about "Deficiency Judgment"
if a law allow the lender to file a lawsuit.
If "Deficiency Judgment" is allowed you should consider
"Short Sale"
