Frequently asked questions
- Should I pay extra principal or invest the money?
- It depends on your mortgage rate vs. expected investment return. If your mortgage rate is higher than after-tax investment returns, paying down debt is the better risk-adjusted move.
- How do I make sure extra payments reduce principal?
- Tell your lender to apply any extra amount to principal, not the next month's payment. Most servicers allow this online or by note on a check.
