Is foreclosure done quicker if home has been discharged in bankruptcy?

A home is not discharged in bankruptcy. The mortgage(s) and home equity loans, lines of credit, etc., are discharged, but you have to abandon the real estate in the bankruptcy. That means the mortgagee can go ahead with a foreclosure if there was none before the filing, once the Chapter 7 is closed. Chances are the mortgagee would ask for relief from stay to go ahead with the foreclosure. The trustee may get any excess from the sale, unless it was exempted.
