The Science of Buying Down Mortgages
Mortgage lenders often present borrowers with a confusing matrix of interest rates on 'Rate Sheets'. They might offer you a 6.5% interest rate for '$0', or a 5.75% interest rate for '2 Points'.
One 'Point' is equal to exactly 1% of your total loan amount. If your loan is $500,000, paying 2 points requires you to bring a massive $10,000 check to the closing table strictly to permanently buy down the interest rate.
The critical question is always the Break-Even calculation. If you bring $10,000 to the closing table to drop the rate, but that drop only saves you $125 a month—it will take you exactly 80 months (nearly 7 years) just to recoup your $10,000 investment. If you sell the house before year 7, buying points was a massive financial mistake.
Frequently Asked Questions
Yes! If you accept an interest rate roughly 0.5% higher than the standard Par rate, the lender will frequently give you 'Lender Credits' (negative points). They will literally pay your closing costs for you at the table, completely eliminating out-of-pocket expenses in exchange for a higher lifetime interest revenue stream.
Unlike the standard Origination fees padding the lender's pocket, genuine Discount Points strictly used to buy down interest rates are generally completely tax-deductible in the year you purchase the primary residence.
