If you walk away from a home that you own, you face the following unpleasant possibilities and realities assuming the home's loan that you have is purchase money (original loan for its purchase):1. your credit will have a personal blemish where depending upon its degree, you might be unable to obtain loans to buy a home or buy some item;2. if the existing loan is "purchase money," meaning used to acquire the property and not a refinanced loan, most likely you would not be subject to any deficiency judgment if the home is foreclosed upon or sold for less than the amount of your loan in that most states have anti-deficiency laws concerning purchase money loans;3. if the existing loan is not purchase money, you very well could be subject to a deficiency judgment if the home is foreclosed upon where the bid amount is less than what is owing on the loan.One option is to try and rent out the home for close to what your mortgage is and you rent a place for less than the home's current monthly debt.Good luck.
