The first thing I want to clarify is that you actually did reaffirm the debt. Many debtors will state their intention to reaffirm a debt in their bankruptcy schedules, but this alone does not reaffirm the debt. You must actually sign and file (either through your attorney or the creditor's attorney) a reaffirmation agreement with the court. It is very unusual for a first or second mortgage to be reaffirmed, and there really aren't many compelling reasons to ever reaffirm. If the debt was actually reaffirmed and you default, the creditor can sue you to collect. If it was not reaffirmed, you have no personal liability and the creditor's only recourse is to foreclose.
