Biweekly mortgage drawbacks

On Andy Prescott wrote an article “Why you don’t need the biweekly mortgage plan”.

He claims that unfortunately often the biweekly mortgage plan does not work as it should. In fact, when mortgage companies take the first two-week payment from you, they do not apply it to the principal, they do not do anything. They keep this payment for two weeks and only after they receive a full monthly payment they apply it to your loan. This approach allows them to minimize their losses from the biweekly mortgage plan.

  • You could set up a new savings account and pay on it every month an amount that at the end of the year will amount to 13-th extra payment of your mortgage payments.

Thus, you will receive additional profit by accruing interest on your savings account during the year. To calculate the amount that will need to be paid each month - take your monthly mortgage payment and divide it by 12 (the number of months in the year).
