We paid off our 30 yr mortgage by adding more than payments each month.
There is a site that estimates overall mortgage payment saving based on principle, interest, and extra amount paid each month. I’m down to 54 dollars interest a month, so I don’t look it up.
Geez people here are so ill informed.
Just get an amortization table, pay extra principle every month ( a pittance in the early years of the mortgage) and knock that loan down to 25 years or less while keeping those low payments…which is what is going to attract new buyers.
Personally went with 30 yr loan, min down
Used extra cash and prepaying principle to knock it down to 15 yr
Then got it paid off
Sending in extra payments is not good. Invest that money instead.
