You can save a significant amount of mortgage interest paid if you make one additional principal and interest payment a year. This will
reduce a 30-year mortgage by around 6 years. It also increases your equity in the home faster. If you choose to pay one additional
mortgage payment a year by paying 1/12 of it each month (make certain to note the extra money is to reduce principal), how much will
you pay each month for a mortgage of $168,000 at 4.50% for 21 years?
