If you are current on your loan payments and able to meet future payments, reaffirming informs the lender that you intend to pay the mortgage. This allows you to keep your home during bankruptcy as long as you abide by the terms of the reaffirmation agreement and make the payments. Reaffirming your mortgage ensures communication between you, the bank, and the credit reporting agencies, says Jennifer Brown of Fifth Third Bank. “When you reaffirm, it’s going to alert the credit bureaus that you’re going through a bankruptcy so it looks like you’re paying your mortgage and shows that you have a history of making payments,” Brown explains. Some lenders require borrowers to reaffirm their mortgage in order to have future payments recorded on their credit report.
