The 13th payment trick
Paying half the mortgage every two weeks makes 26 half-payments — 13 full payments a year instead of 12. That one extra payment, applied to principal, typically cuts 4–6 years and tens of thousands in interest from a 30-year loan.
Do it yourself, free
Some servicers charge for biweekly programs. The identical effect costs nothing: divide your payment by 12 and add that amount to each monthly payment marked 'apply to principal' — same 13 payments a year, no enrollment fee, and you can stop anytime.
