Sounds like you need to discuss this with your bankruptcy attorney. The verbage I believe you need to be clear in your questions is to "re-affirm" the debt (not resign). You may be looking for a loan mod & Ch 13 banruptcy is a form of loan mod. I belive you'll have to qualify under HARP2 to make the new payments and your debts must not excee 31% of your income as just one of the factors. You can keep your home in banruptcy here in Fla provided you continue to make & keep the ALL the mortgage payments current I do not know if the same law applies in CA. Your lender would need to agree, the other creditors too and the BK trustee would need to approve the deal. Please consult your bankruptcy attorney, this is not a question that a Realtor is licensed to answer.
