Why It Matters
Discount points let you trade cash today for a lower rate — and lower monthly payments — for the life of the loan. Whether that trade makes sense depends entirely on how long you hold the property. Buy-and-hold investors with long horizons often come out ahead; short-hold flippers almost never do. The math is simple: divide the upfront cost by the monthly savings to find your break-even point in months, then ask whether you'll still own the property by then.
At a Glance
- 1 point = 1% of loan amount: On a $300,000 loan, one point costs $3,000
- Typical rate reduction: 0.25% per point, though lenders vary — always confirm the specific reduction before paying
- Permanent reduction: Unlike temporary buy-downs, discount points lower the rate for the full loan term
- Break-even math: Upfront cost ÷ monthly savings = months to break even — hold longer than that and you profit
- Flips rarely benefit: Short holding periods mean you exit before recouping the upfront cost
- Tax treatment differs by use: Generally deductible in full for primary residences; must be amortized over the loan term for investment properties
- Seller-paid points: Sellers can buy down a buyer's rate as a concession — a useful negotiating tool in slower markets
How It Works
The basic mechanics. When you take out a mortgage, you can pay discount points at closing to buy down the stated interest rate. Each point costs 1% of the loan amount. In return, the lender permanently reduces your APR and monthly payment. On a $300,000 loan at 7.25%, paying two points ($6,000) might drop the rate to 6.75%, cutting the principal-and-interest payment from roughly $2,047 to $1,946 — a $101/month reduction. Those two points become part of your closing costs and are paid in cash at settlement.
Break-even and the investor calculus. The break-even period is the key number: divide total points cost by monthly savings. In the example above, $6,000 ÷ $101/month = 59 months, just under five years. If you plan to hold the property for seven or more years, paying those points makes financial sense — you'll recover the cost and then pocket $101/month in perpetuity. If you plan to refinance or sell in two years, you'll exit at month 24 having recovered only $2,424 of your $6,000 investment. Points burn cash; only time converts them into savings.
Discount points vs. origination points — a critical distinction. Both are called "points" on the Loan Estimate, but they do different things. Discount points reduce your interest rate. Origination points are lender compensation for making the loan — they do not reduce your rate at all. Discount points buy a lower rate; origination points pay the lender's overhead. Mixing them up leads investors to overpay for the wrong thing. Always confirm in writing which type of points appear on your Loan Estimate and what rate reduction, if any, each delivers.
Real-World Example
Diane is buying a $320,000 rental in Columbus with a $256,000 loan. The lender quotes 7.50% with no points. Diane asks about buying down the rate: two discount points ($5,120) drops it to 7.00%.
At 7.50%, her payment is $1,791. At 7.00%, it drops to $1,704 — an $87/month reduction. Break-even: $5,120 ÷ $87 = 59 months. Diane plans to hold at least ten years, so she runs the full math. Over ten years, she saves $10,440 against a $5,120 upfront cost — net gain of $5,320. She pays the points. By year six, every month starts generating pure savings.
Pros & Cons
- Permanent rate reduction: The lower rate stays in place for the life of the loan, compounding savings over time
- Predictable break-even: The math is simple and certain — no market assumptions required, just hold-period discipline
- Useful in high-rate environments: The absolute dollar savings per 0.25% reduction are larger when rates are high, making points more valuable than in low-rate markets
- Seller-paid option: In buyer-friendly markets, you can negotiate for the seller to pay points on your behalf, reducing rate without spending your own capital
- Improves cash flow immediately: On a buy-and-hold rental, a lower rate means more net operating income from day one
- Ties up capital at closing: Points require cash at settlement — capital that could fund reserves, a second acquisition, or rehab work
- Wasted on short holds: Flippers and short-term investors almost always exit before break-even, making points a net loss
- Refinance risk: If rates fall and you refinance within a few years, you forfeit the points — you pay twice to buy down the rate
- No recovery if you sell early: Points are not transferable and not refundable; an early sale means walking away from unrecovered cost
- Investment property tax timing: Unlike primary residences where points may be deducted in full in year one, investment property points must be amortized over the loan term — reducing the immediate tax benefit
Watch Out
- Confusing discount points with origination points: Before paying any points, confirm in writing whether each point reduces your rate or simply compensates the lender. Origination points are a cost of doing business, not a rate buy-down. One type saves you money long-term; the other does not.
- Ignoring the refinance scenario: Points only pay off if the loan stays in place past break-even. If there's a reasonable chance you'll refinance — because rates drop or you pull equity — model that scenario before committing.
- Seller-paid points and purchase price: When sellers pay points, it often comes with a higher purchase price. Run the numbers both ways: does the rate reduction from points outweigh the higher loan balance you're carrying?
- Temporary buy-downs are different: A 2-1 buy-down (common in new construction) lowers the rate by 2% in year one and 1% in year two before reverting to the full rate. This is seller-paid and temporary — not the same as permanent discount points, and it requires a plan for when the full rate kicks in.
The Takeaway
Discount points are a cash-now-for-savings-later trade that rewards patient, long-term investors and punishes anyone who exits early. The break-even math takes two minutes: upfront cost divided by monthly savings. If your planned hold exceeds that number with room to spare, paying points is a defensible use of capital. If your hold is uncertain or short, keep the cash in reserves where it can work for you without conditions.
