Yes, you can make a regular payment on your mortgage as well as a principal only payment through Online Banking.
Under the Move Money Tab are options to make a payment from your Third Federal account or from an external account. After selecting the source of the payment and completing the payment information there are two options to choose from when making an online payment to your loan. The first is Regular Payment. Your payment is applied to principal, interest, escrow and any fees due. Your due date will advance one month.
The second option is Principal Only Payment. Only choose Principal Only Payment when you have already paid your monthly amount due and want to make a payment to principal only.
If you choose Principal Only Payment and you have already paid your monthly amount due, your payment will be all be applied to the principal and your Due Date will not change.
However, if you choose Principal Only Payment and have an amount due, your payment will be applied to the amount due first and the remainder will be applied to Principal.
