Lump-sum Additional Payment
It may not be possible for you to pay more every month or even every year. But it's important to note that most mortgage contracts will allow additional principal payments at any time. You can benefit from this rule to pay extra on your principal when you get some extra money. If, for example, you were to receive a large gift or tax refund just a few years into your mortgage, you could apply a portion of this money toward your mortgage loan principal, resulting in huge savings and a shorter payback period. Unless the mortgage loan is very large, even a few thousand dollars applied early can produce huge benefits over the life of the loan.
