Discount points allow you to lower your interest rate. While this video simplifies things to help you remember, “points” are essentially prepaid interest with each point equaling 1% of the total loan amount. Generally, for each point paid on a 30-year mortgage the interest rate is reduced by 1/8 (or.125) of a percentage point. When shopping for loans, ask lenders for an interest rate with 0 points and then see how much the rate decreases with each point paid. Discount points are smart if you plan to stay in a home for some time since they can lower the monthly loan payment. Points are tax deductible when you purchase a home and you may be able to negotiate for the seller to pay for some of them.
