Can I keep my home if I file for bankrupcy?

I have about $32,000 in unsecured debt, and I am slowly draining my savings to pay down my bills. We recently moved into a home almost 2 years ago with no money down, so I have basically no equity. I have 3 vehicles. I am easily meeting my mortgage, and my secured debt, I have no credit card balance. I would like to file to wipe out that unsecured debt, but do not want to jeopardized my home, or at least 2 of my cars. As of now my credit score is very good, (middle 700's).
