Hi and thank you for your question.
Since you are in a confirmed chapter 13, you should bring a motion for approval of the loan modification. If you miss payments, the lender may bring a motion to modify the automatic stay
protection the bankruptcy offers you. This allows the lender to work with you directly, but also allows the lender to foreclose if you are behind on the mortgage. You may have to take a leap of faith if you want to skip payments (even if told to by the lender) for if the stay is modified, and your loan modification is not approved, then you will need to cure the default to avoid foreclosure. You should put the mortgage payment aside and not spend it, so if you need to cure if the loan modification is not approved, you'll be able to. If you want to walk away from the house, you can bring a motion to modify your plan based on your change of situation (the move) to adjust the case based on your new expenses (and income?) If you want to let them foreclose, you can, and have your modified plan reflect that. Otherwise, you may even be able to convert your case to chapter 7
, surrendering the home too, and discharging the balance.
As always, talk to your bankruptcy attorney to review these matters, so that they can comply with all local rules and case law. Your case will still be handled where you filed, regardless of where you move to, unless you file a motion to change venue. Good luck to you.
