<prompt> Human: Is there any benefit to making extra payments towards principle if you know you wont pay it off? I bought a house last year and I know Im moving in two years. We havent decided whether to sell or rent it out through property management after we leave. Is there any tangible benefit to allotting extra cash to the mortgage?  <response>: If you do the math, basically your extra payment will be like saving money in a saving account at the mortgage rate minus less deduction you will have with income tax.So, if you made 100 extra payment a month at 3 mortgage rate and 24 months, you will be ahead 70. In a 1 saving account, you will make 23 in two years.Adjust it to how much you want to over pay and your mortgage rate, it could be a nice little bump or it could be so small, it doesnt really matter.
