Frequently Asked Questions

How does a biweekly mortgage save me money?

Paying half your monthly mortgage every two weeks results in 26 half-payments per year - equivalent to 13 full monthly payments instead of 12. That extra payment goes straight to principal, typically shaving 4–6 years off a 30-year mortgage and saving tens of thousands in interest. On a $300,000 loan at 6.5%, biweekly payments save about $61,000 over the life of the loan.

Do I need to enroll in a special biweekly program?

No - you can replicate biweekly savings yourself by adding 1/12 of your normal monthly payment to each month. Many banks charge $200–$400 setup fees and $5–$10 per payment for "biweekly programs" that often just hold your money and remit monthly anyway. Simply paying extra principal each month delivers the same result for free.

Will my lender accept biweekly payments?

Some lenders accept and apply biweekly payments correctly; others hold partial payments in suspense until a full monthly payment arrives. Confirm with your servicer before switching. The DIY alternative - adding 1/12 to your monthly payment - works with every lender because it is just an extra principal payment.

Is biweekly payment better than just refinancing?

They serve different purposes. Refinancing lowers the rate (and thus the required payment); biweekly payments accelerate payoff at the existing rate. The biggest savings come from doing both - refinance to a lower rate when available, then send extra principal payments on the new lower-rate loan.
