Will, the short answer to your last question, the one nobody above touched: lenders offer points because points let them advertise a lower rate than they can actually deliver at par. You pay the difference. The six answers above handle discount points and break-even correctly. Three things are missing, and the third is your question. First, two different products are sold under the word buydown. A permanent buydown is what people mean by discount points. You pay cash at closing and the note rate drops for the life of the loan. Roughly one point (one percent of the loan) buys near a quarter point of rate. A temporary buydown is a different animal. In a 2-1, your rate sits two points below the note rate in year one and one point below in year two, then steps up to the note rate in year three. A 3-2-1 does the same over three years. Your note rate never changed. Money sits in an escrow account and is released monthly to cover the difference. The critical detail: you qualify on the note rate, not the teaser rate, so you must afford the year three payment on day one. The funding almost always comes from a seller or builder concession, which is why builders love them right now. Second, the tax treatment, which changes the real cost. Under IRS Publication 936, points paid to buy or build your main home are generally deductible in full in the year you pay them, if conditions are met: paying points is established practice in your area, the amount is computed as a percentage of the loan and shown on your settlement statement, and the cash you brought to closing at least equals the points. Refinances are different. Points paid to refinance generally cannot be deducted all at once. You spread them over the loan's life, so points on a 30-year refinance come off in 360 slices. Pay it off early and the unamortized remainder generally becomes deductible in the payoff year, with an exception if you refinance with the same lender. That changes your break-even. Points on a purchase are cheaper after tax than the sticker suggests, if you itemize. Points on a refinance are not. Third, your actual question: why does a lender offer points? Because rate and cost are one dial, not two. Every lender publishes a rate sheet with a price attached to each rate: below a certain rate you pay the lender, above it the lender pays you. Points are the paying end. They let a lender advertise 6.25 percent when the honest par rate that day is nearer the 6.69 percent the Freddie Mac survey showed for the week of August 6, 2026, the difference buried in "plus 1.5 points." The mirror image is the lender credit, the more useful half for most buyers. You accept a rate above par and the lender writes a check toward your closing costs. If you are short on cash, or expect to be gone within four years, that is often the better trade. Do this. Ask every lender for the same loan quoted three ways on a Loan Estimate: at par with zero points, with one point paid, and with a lender credit. Same amount, same day, same lock. Side by side, the tradeoff becomes arithmetic you can check. One 2026 note. You asked in early 2024, when the 30-year averaged 6.94 percent. Rates have eased since, so rerun any break-even math on a current quote. I am a real estate professional, not a lender and not a tax advisor, so confirm the specifics with a CPA and a licensed loan officer.
