Not sure if this is where I need to post.
I don't know too much about BK, but I would suggest first contacting the BK lawyer that you used. Gather your thoughts and write down your questions. Depending on what the lawyer says, then you can decide wether to try to sell or walk away. If you decide to sell, maybe contact a local realtor that can first do a market analysis to see what your house might sell for. Then you would know if it would be worth it. Good luck & keep us posted!
