If you can, yes! You’ll end up shaving about 5 years off your loan by doing so (the number of years will vary depending on loan amount and interest rate). Many servicers allow this option once you set up your payments online. If a third party company offers to manage biweekly payments for you though, please do not relinquish that control – there is too much at stake.

However, if your servicer allows for biweekly payments, and you feel good about the outgoing payment responsibility, do so. Alternatively, you can keep your monthly payments as is, and make one additional mortgage payment per year (so 13 payments in one year), and the result is roughly the same. Any additional amount you pay towards your principal at any given point will shave time off your loan, therefore allowing you to pay it off sooner as well as save in overall interest paid over the life of the loan.
