Yes, if you’ll break even on the cost of the mortgage points before you sell your home. Mortgage points allow you to “buy down” a lower interest rate, and typically only make sense if you plan to live in your home for a long time. One point typically equals 1% of your loan amount, and reduces your rate by up to .25% percentage points, although the cost may vary by lender. You may be able to deduct refinance points on your taxes.
