Mortgage points on an investment property: compare the actual quotes
Jun 29, 2026 · 11 min read
A lender may offer several combinations of rate, points, credits, and fees. The only reliable comparison uses same-day written options for the actual borrower and property. This guide preserves the break-even math with hypothetical quotes, then shows which lender, tax, liquidity, and exit questions must be verified.
What a point actually buys
A quote may use one point to mean 1% of the loan amount. Confirm whether each charge is a discount point, origination charge, or another fee, and read the rate change from the lender's written ladder:
Point charge = quoted percentage × loan amountRate change per point = lender's written quote, not a fixed ruleIn the hypothetical below, a $200,000 loan makes one quoted point $2,000. The rate change, however, is an assumption supplied by the example. Ask for the full same-day ladder in writing and compare payment, APR, fees, cash to close, lock terms, and any prepayment charge at each rung.
Two distinctions trip people up. Discount points buy down your rate; origination points are simply a fee the lender charges to make the loan and do nothing to your rate — when a quote lists "2 points," confirm which kind. A lender-credit option may trade a higher rate for a closing-cost credit. Its value depends on the written quote, how long the loan remains outstanding, and all other terms; it is not automatically preferable for a short expected hold.
The break-even, worked
A simple screening ratio estimates how long monthly payment savings take to recover the incremental upfront cost.
Break-even (months) = Cost of points ÷ Monthly payment savingsThe following hypothetical uses a $200,000, 30-year loan, a 7.0% base-rate assumption, and an assumed 0.25-percentage-point rate change per point. These are not current quotes. You can reproduce the payment arithmetic on the mortgage payment calculator:
| Points (cost) | Rate | P&I / mo | Saved / mo | Break-even |
|---|---|---|---|---|
| 0 ($0) | 7.00% | $1,330.60 | — | — |
| 1 ($2,000) | 6.75% | $1,297.20 | $33.41 | ~60 mo |
| 2 ($4,000) | 6.50% | $1,264.14 | $66.47 | ~60 mo |
| 4 ($8,000) | 6.00% | $1,199.10 | $131.50 | ~61 mo |
Under those assumptions, one point trims the payment about $33 per month and the simple break-even is about 60 months. That result is specific to the illustrative ladder. It ignores opportunity cost, time value, taxes, transaction changes, and the chance that the loan is sold, refinanced, modified, prepaid, or otherwise ends.
Why the break-even barely moves in this hypothetical
In this simplified ladder, cost and assumed savings scale similarly, so the simple break-even changes little. A real ladder may not be linear and may change other fees or eligibility. Calculate each pair of actual quotes separately.
| Rate cut per point | Saved / mo (1 pt) | Break-even |
|---|---|---|
| 0.375% (hypothetical A) | $49.98 | ~40 mo (3.3 yr) |
| 0.250% (hypothetical B) | $33.41 | ~60 mo (5.0 yr) |
| 0.125% (hypothetical C) | $16.75 | ~119 mo (10 yr) |
These three assumed ladders show that the break-even can change materially with the rate reduction. They do not identify a normal, favorable, or unfavorable quote. Use the lender's actual ladder and the expected hold and exit scenarios.
Tax treatment must come from the actual charge and loan
Do not copy primary-residence treatment to a rental or assume every charge called a point is prepaid interest. Classification and timing can depend on the charge, loan purpose, use, payment period, accounting method, refinance or payoff facts, and current law. The rental-property tax guide provides a general checklist, but the closing documents and taxpayer facts control.
A sale, payoff, modification, or refinance may change the treatment of any remaining amount, but the result is not universal. Have a qualified tax professional classify the fee and determine the applicable timing before using a tax benefit in the break-even.
How points can change a modeled DSCR
A lower modeled rate reduces the payment and can increase a debt-service-coverage ratio. Whether that changes eligibility or pricing depends on the lender's accepted rent, payment definition, threshold, rounding, fees, reserves, and full matrix. The table below continues the hypothetical $200,000 loan with $18,200 of modeled NOI:
| Points | Rate | Annual debt service | DSCR |
|---|---|---|---|
| 0 | 7.00% | $15,967 | 1.14 |
| 1 | 6.75% | $15,566 | 1.17 |
| 2 | 6.50% | $15,170 | 1.20 |
In the example, two points move modeled DSCR from 1.14 to 1.20. If a lender's written matrix used that threshold and accepted every other input, the change could affect the file. Actual DSCR-loan programs vary, and modeled DSCR does not establish approval, rate tier, or closing. Obtain the lender's calculation and complete written terms before paying non-refundable fees.
What points do to cash-on-cash
In a model, points can lower the payment while raising the cash in the deal. Run both effects through cash-on-cash on the example — $50,000 down, $7,500 of other closing costs, $18,200 NOI:
| Scenario | Cash in | Cash flow / mo | Cash-on-cash |
|---|---|---|---|
| 0 points (7.00%) | $57,500 | $186 | 3.88% |
| 2 points (6.50%) | $61,500 | $253 | 4.93% |
Under the hypothetical inputs, cash-on-cash rises from 3.88% to 4.93%. That snapshot assumes the stated payment savings continue; it does not prove the points outperform over the hold. A refinance at month 36 in this example would produce about $2,400 of payment savings against $4,000 of upfront cost before taxes, time value, or other effects. Compare a full hold-period cash-flow schedule, not the first-year ratio alone.
A refinance-before-break-even scenario
A simple break-even assumes the quoted loan remains outstanding long enough for payment savings to recover the upfront charge. In this article's hypothetical two-point case, ending the loan at month 36 produces about $2,400 of payment savings against $4,000 of upfront cost, before taxes, time value, transaction costs, or any payoff terms. That is an illustrative shortfall, not a forecast of future rates or a recommendation to refinance.
Compare each written quote across several loan-duration scenarios, including a possible sale, payoff, or refinance the rental. Do not assume a future refinance will be available or economical, and do not assume a lender credit is free; it may be paired with a different rate or other terms. For every option, compare total cash, cumulative payments, remaining balance, exit costs, and the modeled loan constant over the same time horizons.
A decision checklist for the written options
For each option, compare the simple break-even with realistic hold and loan-duration scenarios; confirm the lender's DSCR calculation, pricing tiers, reserves, and eligibility in writing; and measure the effect on liquidity. A modeled threshold crossing does not establish approval, and a short break-even does not make the rest of the loan terms favorable.
Also compare the quoted point option with a zero-point option, any lender-credit option, required reserves, and a larger down payment. If a quote includes a temporary buydown, obtain the introductory and permanent payment schedules, funding source, qualification method, and all terms in writing. Model the permanent payment and do not treat an introductory payment as a permanent rate reduction.
FAQ
How much does one mortgage point cost and how much does it lower my rate?
A quoted point commonly means 1% of the loan amount, but confirm whether the charge is a discount point, origination charge, or another fee. The rate change is not fixed by the word 'point'; it comes from the lender's same-day written rate-and-fee ladder for the actual file. Compare note rate, APR, payment, cash to close, lock terms, and every fee at each option.
What is the break-even on buying mortgage points?
A simple pre-tax screen divides the incremental upfront cost by the incremental monthly payment savings. The result depends entirely on the paired written quotes and does not capture taxes, opportunity cost, time value, loan changes, sale, refinance, default, or prepayment terms. Compare the simple break-even with a full hold-period cash-flow analysis.
Are points on a rental property tax-deductible?
Tax treatment depends on what the charge actually is, loan purpose, property use, payment period, accounting method, refinance or payoff facts, and current law. Do not copy primary-residence treatment or assume an immediate deduction for a rental. Have a qualified tax professional classify the charge and determine the timing from the closing documents.
Should I buy points or just put more money down?
Run both written scenarios. Points may reduce the payment while increasing cash to close; a larger down payment changes the loan balance, leverage, reserves, and possibly pricing or eligibility. Compare total cash, payment, DSCR under the lender's method, cash-on-cash, liquidity, break-even, and exit scenarios. Neither option is automatically better or an approval guarantee.
The bottom line
Mortgage points exchange more cash at closing for the rate and payment shown on a particular quote. There is no universal break-even, yield, tax treatment, or approval effect. Compare the lender's complete same-day ladder, calculate each option over multiple hold and loan-duration scenarios, and have a qualified tax professional classify the actual charges. If the modeled rate changes a payment-driven DSCR, confirm the lender's own inputs and threshold rather than relying on the model. The TrueCap analyzer recalculates payment, cash flow, DSCR, and cash-on-cash from the rate and costs you enter; it does not provide a quote, verify eligibility, or give lending, investment, legal, or tax advice. Reconcile the model with the final lender documents before committing funds.
