Loan Modification

A loan modification is a permanent change to one or more original terms of a loan, such as the interest rate or repayment period, agreed to by borrower and lender.

What Is a Loan Modification?

A loan modification is a change to the original contract of a loan that the borrower and lender agree to make, usually to lower the risk of default when the borrower is struggling to keep up with payments. Unlike refinancing, which replaces an existing loan with a new one, a modification changes the terms of the current loan itself. Modifications are most often discussed in connection with mortgage loans, but they can also apply to student loans, auto loans, and other types of debt.

How It Works

A modification can change one or more features of the loan. Common changes include:

  • Lowering the interest rate
  • Extending the repayment period
  • Switching from an adjustable rate to a fixed rate
  • Adding missed payments to the end of the loan
  • Reducing the unpaid principal balance, which is less common

Lenders typically review the borrower's income, expenses, and financial hardship before agreeing to changes. The process often involves a formal application and supporting documents. Because the new terms replace the original contract, a modification is generally a lasting change. This sets it apart from forbearance, which only pauses or reduces payments for a limited time.

Example

Consider a homeowner whose income drops and who falls behind on monthly mortgage payments. Instead of selling the home or losing it, the homeowner asks the lender for a modification. The lender agrees to lower the interest rate and extend the loan term, which reduces the required monthly payment. The homeowner then repays the balance under the revised schedule over a longer period.

Why It Matters to Investors

Investors who hold loans or securities backed by loans may be affected when borrowers receive modifications, because changes to payment schedules can alter the expected cash flows. A modification may also be reported to credit bureaus and can affect a borrower's credit score. Lenders use modifications as an alternative to foreclosure, which is often costly for both sides. However, modifications have tradeoffs. Borrowers may pay more total interest over a longer term, and not every borrower qualifies.
