The Bi-Weekly Payment Strategy
Key Insights & Concepts
The "Bi-Weekly" strategy is one of the simplest ways to save significant money on a mortgage. Instead of paying your mortgage once a month (12 payments a year), you pay half of that amount every two weeks (26 half-payments a year).
Why does it work?
26 half-payments equal 13 full monthly payments. By simply restructuring when you pay, you make one extra full mortgage payment every year without feeling a major pinch in your monthly budget. This extra principal payment reduces your balance faster, which in turn reduces the interest charged in future months.
Does my lender allow this?
Most lenders allow you to make extra principal payments, but they may not offer a formal "bi-weekly program." You can achieve the exact same result yourself by simply adding 1/12th of your monthly payment to your regular check each month.
