I dont know for sure if you have any equity in your house. However, instead of walking away, if you decide you cant keep the house, you may want to try a "deed in lieu of foreclosure". I work in the finance industry and it could save you and the mortgage company lots of time and money. Basically, you just sign the deed over to the bank and they agree to take it and sell the house. It is a way to skip over the foreclosure mess.
