deed in lieu & bankruptcy

I went through a bankruptcy in 2007. My home was included in it. I did not re-affirm with the bank, but have continued to make my payments. According to the bankruptcy and my lawyer, I am not responsible for any defiency that may occur if say I did a short sale. I recently lost my job of 17 years due to a reduction in force. Is a deed in lieu my best option? I have been rebuilding my credit score and am finally in good shape. Will a deed in lieu do any damage to my credit since I already was granted defiency protection? We have been trying to sell, but our home is in a higher price range than the majority of home buyers in my area can afford. We are willing to walk away. Need some advice
