This question was asked in 2008 so the hosue must be sold by now. But I am answering this so that others in your situation can benefit from it.
Before you sell to anyone please find out the value of the house. Also get a good attorney to represent you.
Beware of investors who will try to take advantage of your situation if you have hardships.
Talk to your lender. Look up resources at www.hud.gov and talk to counselors in your area.
