Discount Points

Discount points function as prepaid mortgage interest that the lender collects upfront in exchange for accepting a lower yield on the loan over its lifetime. When you pay a point, the lender receives cash immediately at closing rather than collecting that same interest spread gradually through higher monthly payments. The exact mechanics are straightforward: each point equals exactly 1% of the loan principal, so on a $300,000 mortgage one point costs $3,000, on a $500,000 mortgage it costs $5,000, and on a $600,000 jumbo loan it costs $6,000. The corresponding interest rate reduction typically ranges from 0.125% to 0.375% per point depending on the lender's pricing engine, loan program type, and broader bond market conditions. Conventional loans backed by Fannie Mae and Freddie Mac, FHA loans, VA loans, and USDA loans each have their own guidelines regarding how many points can be charged and what rate reduction formulas apply. FHA loans, for example, have a standard rate reduction structure that may differ from conventional loan pricing, and they also have upfront mortgage insurance premium (UFMIP) that can interact with the points decision.

The Internal Revenue Service treats discount points as prepaid interest for tax purposes, which means they are generally deductible as mortgage interest in the year they are paid for a purchase money mortgage if specific IRS requirements are satisfied: the loan must be secured by the borrower's primary residence, points must be calculated as a percentage of the principal amount, charging points must be an established business practice in the geographic area, and the points paid must not exceed the amount generally charged in the area. For refinance transactions, points cannot be deducted in full in the year paid but must instead be amortized and deducted ratably over the life of the new loan, unless part of the refinance proceeds are used for home improvements, in which case a portion may be currently deductible. The APR (Annual Percentage Rate) calculation mandated by TILA incorporates discount points and other prepaid finance charges to give borrowers a standardized way to compare the true cost of borrowing across different lenders. Because points increase the APR relative to the note rate, comparing APRs across lenders automatically accounts for differences in points charged, making APR a critical shopping tool. Borrowers should request multiple Loan Estimates from different lenders and compare both the interest rate and the APR to determine which combination of rate and points best fits their financial situation and expected holding period.

The decision to purchase discount points is fundamentally a bet on how long you will keep the mortgage, and getting this decision right can save or cost you tens of thousands of dollars. For borrowers purchasing a long-term or forever home where they plan to stay for 10 to 30 years, buying points is often an excellent financial move. Consider a $450,000 loan at 7% where buying two points for $9,000 reduces the rate to 6.5%. The monthly savings would be approximately $330, the break-even period would be roughly 27 months, and the total interest saved over 30 years would exceed $118,000. This is a compelling return on a $9,000 upfront investment for a long-term homeowner. Conversely, for borrowers in starter homes, those planning to relocate within five years for career reasons, or those who expect to refinance when market rates decline, paying points is generally a losing proposition. The break-even period for most point purchases falls between 3 and 7 years, and if you exit the loan before that point, you have effectively paid extra for a benefit you never fully realized. Borrowers should also consider the opportunity cost of the cash spent on points: that same $4,000 to $9,000 could instead be used to make a larger down payment (reducing the loan amount and therefore the monthly payment permanently), to fund necessary home repairs or renovations, or to be invested in a diversified portfolio where it could earn compound returns over the same period. Many lenders also offer lender credits, which are the inverse of points — the lender offers a higher interest rate in exchange for covering some or all of the borrower's closing costs. Comparing the points scenario, the base scenario, and the lender credit scenario side by side is the best way to determine which financing structure optimizes your specific financial goals.
