If you answered yes to any of these below questions, then your best option is a short sale.

* Are You Facing a Foreclosure?
* Have You Been Denied a Modification?
* Are You Upside Down On Your Loan?
* Do You Want to Minimize Damage to Your Credit?
* Do You Want to Postpone Foreclosure and Deficiency Judgments?
* Do You Want Solutions Towards a Fresh Start?
* Do You Want to Dispose Your Debt and Avoid Future Collections?
* Are Your Mortgage Payments Skyrocketing?

But you must not be able to answer yes to

Do you have any assets anywhere that you could liquidate to satisfy the portion of this debt that is currently owed.
Or if current that could help keep you current even if the payments are going to escalate.

You can not just walk away without consequences.
