A temporary mortgage rate buydown lowers your payments for a limited period; a permanent buydown uses upfront discount points to lower the rate for as long as you keep the loan. Choose permanent points when their cost is likely to break even before you sell or refinance. Choose a temporary buydown when you value early payment relief, especially if a seller or builder funds it, and can comfortably afford the full note-rate payment once the subsidy ends.
Neither option is automatically cheaper. Compare written loan scenarios using the same loan amount and terms, and base affordability on the contractual payment—not just a temporary introductory payment.

What is the difference between a temporary and permanent buydown?
A temporary buydown uses a funded account to subsidize some of the borrower’s early payments. A permanent buydown charges upfront discount points in exchange for a lower interest rate on the mortgage.
With a temporary buydown, funds are deposited into a separate account and released over the agreed period to reduce the payments the borrower makes. The loan’s note rate does not change. Fannie Mae’s Loan Delivery Job Aid explains that “the actual note rate and monthly payment that the borrower is obligated to pay is never actually reduced,” and that the full rate and payment must appear in the mortgage documents. The subsidy runs out on schedule, after which the borrower pays the note-rate amount.

A permanent buydown changes the interest rate in exchange for upfront points. The resulting payment reduction continues while the borrower keeps that mortgage, but the point cost is paid at the outset. Points and rate reductions are lender-specific. Chase’s consumer guidance says a point usually costs 1% of the loan amount and may reduce the rate by about 0.25%, depending on the lender; those are conventions, not a quote or guarantee.
In short, the temporary option changes the payment path for a limited time, while the permanent option changes the rate for the life of the loan. Both require comparing the dollars paid upfront or contributed, the payments over time, and how long you expect to keep the mortgage.

A temporary buydown account pays part of the borrower’s scheduled payment during the subsidy period. The borrower’s contractual rate and full note-rate obligation remain in place throughout.
In a 3-2-1 structure, the payment is calculated as though the rate were three percentage points below the note rate in year one, two points below in year two, and one point below in year three. A 2-1 structure typically provides a two-point reduction in the first year and a one-point reduction in the second; after the subsidy ends, the payment is based on the note rate. The reduced-rate figures describe how the subsidy is calculated, not a permanent change to the note rate.
For example, if the note rate is 7%, a 2-1 schedule uses a 5% payment calculation in year one, 6% in year two and 7% thereafter. A 3-2-1 schedule would use 4%, 5% and 6% calculations in its first three years, then return to 7%. The exact dollar subsidy depends on the loan balance, term and amortization schedule, so a percentage label alone is not a cost comparison.
Fannie Mae’s Selling Guide says the temporary buydown funds may come from the borrower, lender, employer, seller, or another interested transaction party. Its Selling Guide limits the buydown period to no more than three years and says the portion of the interest rate paid by the borrower may not increase by more than one percentage point in each one-year interval. The account must be established and fully funded by loan delivery under the cited Fannie Mae rules. These requirements apply in the Fannie Mae delivery context; other loan programs and lenders may have different rules.

The account is not a cash rebate that you can freely withdraw. Its purpose is to make scheduled payment contributions as they come due. Ask for the agreement showing the initial deposit, release schedule, responsible party and treatment of any balance if the loan ends early.

Because the full contractual payment remains due under the loan terms, do not treat the lower initial payment as proof that you qualify for or can afford the mortgage. Freddie Mac’s guidance for the fixed-rate temporary buydowns it covers requires qualification using the note-rate payment. Confirm the requirements for your specific loan with the lender.
How do permanent discount points pay off?
Permanent points are worthwhile only if the monthly savings recover their upfront cost while you still have the loan. To estimate the break-even point, divide the cost of the points by the monthly payment savings. The result is the number of months it takes for the savings to equal the upfront charge.
For example, Chase’s hypothetical uses a $400,000, 30-year fixed-rate mortgage at 6%, with an illustrated payment of about $2,398. In that example, two points cost $8,000 and save about $127 per month, producing a 63-month break-even. That calculation is specific to Chase’s example, not a general price or expected result for another borrower. Your lender’s point price, rate reduction, loan amount, and payment will differ.

1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsAt the common convention of 1% of the loan amount per point, one point on a $400,000 loan would be $4,000, but the lender’s disclosure controls. A quote can assign a different price or a different rate reduction, and the same number of points can produce different savings at different rates. Request both the no-points rate and the points rate on the same day and lock assumptions before doing the calculation.
Compare the break-even period with a realistic estimate of how long you will keep the loan—not only how long you expect to own the home. Selling or refinancing before break-even can mean you pay the upfront cost without receiving enough monthly savings to recover it. If you keep the loan past break-even, the projected savings may exceed the point cost, but the actual result still depends on the quoted terms and when the loan is paid off.
Use the same loan assumptions when you compare offers. A lower rate or payment alone does not show the total cost: include points, lender fees, and other costs in the written estimate. LendingTree advises comparing APR, fees, and total borrowing cost when evaluating lender-credit offers as well.
How should you compare the costs and payment schedules?
Ask the lender for written scenarios that use the same loan amount, term, and other assumptions. Compare the full payment path, cash due at closing, and total dollars—not just the first-year payment or advertised rate.

- Get the contractual payment. Ask for the payment at the note rate and the full monthly housing cost. Principal and interest are only part of that cost; property taxes, homeowners insurance, mortgage insurance, and association dues may also affect your budget.
- Request each buydown schedule. For a temporary offer, get the payment for every subsidy year and the payment after the subsidy ends. For permanent points, get the rate, point cost, and resulting payment.
- Identify who funds the upfront cost. Separate money you must bring from a seller, builder, lender, employer, or other contribution. Ask the lender to confirm in writing that the funding source and its intended use are permitted for your loan.
- Calculate permanent-point break-even. Divide the quoted point cost by the quoted monthly savings. Compare that number of months with how long you reasonably expect to keep this mortgage.
- Compare alternate uses of any credit. Ask for comparable written estimates using the available seller or builder credit for a temporary buydown, permanent points, closing costs, or a purchase-price reduction. The best use depends on the loan terms and your priorities; do not assume a payment subsidy is the only available choice.
- Check the early-payoff terms. Read the temporary buydown agreement and ask what happens if you sell, refinance, or otherwise pay off the mortgage before the subsidy account is exhausted.
A 2-1 illustration shows why the schedule matters. LendingTree models a $320,000, 30-year loan at a 7% note rate, with principal-and-interest payments of $1,718 in year one at the 5% temporary rate, $1,919 in year two at 6%, and $2,129 at the 7% note rate thereafter. Its estimated subsidy cost is $7,452. These are LendingTree’s hypothetical figures, not a current offer, typical cost, or forecast for your loan.
The figures above isolate principal and interest. A lower subsidized payment does not necessarily lower taxes, insurance, or other housing expenses. Ask the lender to show the total monthly obligation alongside the principal-and-interest schedule so you can budget for the full amount.
Make the comparison on a month-by-month timeline. A permanent option may require more cash at closing but produce the same payment every month. A temporary option may require little or no borrower cash when a transaction credit funds it, yet create a clearly higher payment later. Listing the cumulative out-of-pocket cost at 12, 24, 36 and 60 months can expose a difference that a headline rate hides.
Also check whether the quoted credit is contingent on using a particular lender or closing by a deadline. A credit that expires, changes with the rate lock or cannot be combined with other concessions should not be treated as cash you can use for any purpose. Loan-program concession limits and eligible uses vary, so obtain the lender’s written confirmation.
When should you choose a temporary buydown?
A temporary buydown may fit when you want early payment relief, can afford the full note-rate payment, and the source of subsidy makes the cost worthwhile. It can be especially attractive to compare when a seller or builder is offering a credit, because the same credit might instead pay closing costs, buy permanent points, or reduce the purchase price.
The key question is whether you can manage the step-up when the subsidy declines or ends. Write down each scheduled payment, including the full note-rate payment after the temporary period. If that final amount would strain your budget, an initially lower payment does not solve the underlying affordability problem.
A temporary structure can be useful when you expect income to rise, a planned expense to end, or a short transition period after moving. Those are personal budgeting assumptions, not guarantees. Build a reserve using the post-subsidy payment, rather than treating the first-year difference as money available for new obligations.

Also consider what happens if the loan ends early. Fannie Mae’s Selling Guide says buydown funds are not refundable unless the mortgage is paid off before all funds have been applied; disposition is handled under the guide and the buydown agreement, including provisions concerning payoff, foreclosure, or assumption. Read the agreement rather than assuming unused funds will be returned to you.

Permanent points may make sense when the quoted reduction in rate creates meaningful monthly savings and you expect to keep this mortgage beyond the calculated break-even period. They are less compelling when the upfront cost uses cash you need for reserves or when you expect to sell or refinance before the savings catch up with the fee.
Get a specific quote rather than estimating the rate reduction from a rule of thumb. Ask the lender to show the no-points option alongside the points option, with the upfront cost and payment for each. Then calculate break-even from those actual figures and consider your likely loan timeline.
Do not assume that a lower interest rate necessarily means the better overall deal. A rate reduction has value only in relation to its cost and the time you benefit from it. Compare closing costs and total borrowing costs alongside the payment change.
Permanent points also compete with other uses of cash at closing. Emergency reserves, prepaid taxes and insurance, moving expenses and necessary repairs can have more immediate value than a lower payment. If paying points would leave you unable to handle an income interruption or an unexpected home expense, the mathematically lower rate may create greater practical risk.

Common mistakes to avoid
- Comparing different loans. A temporary quote and a points quote are meaningful only when amount, term, loan type and rate-lock assumptions match.
- Using the first-year payment as an affordability test. Under the cited Freddie Mac guidance, qualification for covered fixed-rate temporary buydowns uses the note-rate payment.
- Assuming the seller’s credit is yours to keep. The credit must be used under the loan program and written agreement; it may not become unrestricted cash.
- Ignoring the end date. Put the first unsubsidized payment on your calendar and test that amount against your budget.
- Assuming rates will fall and you will refinance. A future refinance is uncertain, and an early payoff can limit the value of points or affect remaining temporary funds.
- Leaving taxes and insurance out of the budget. The advertised buydown payment generally shows principal and interest, not the entire housing bill.
What should you ask your lender before deciding?
Use these questions to make the two options comparable and uncover risks that an introductory payment may obscure:
- What is the note rate, and what is the full principal-and-interest payment at that rate?
- For the temporary option, what is my payment in each year, how much is deposited into the subsidy account, and who funds it?
- For the permanent option, what is the point cost, the resulting rate, and the monthly savings compared with the no-points loan?
- What is the payment after including estimated taxes, insurance, mortgage insurance, and any association dues?
- Can the available seller, builder, or lender credit be used for points, a temporary buydown, closing costs, or a price reduction under this loan’s rules?
- How will the lender qualify me, and does the applicable program require qualification at the note-rate payment?
- If I pay off the mortgage early, what happens to any unused temporary buydown funds under the written agreement?
- Can I have all scenarios and their assumptions in writing so I can compare the same loan amount and term?
How we compared the options
This comparison focuses on the features that determine borrower cost and risk: whether the note rate changes, when the subsidy ends, who funds the upfront amount, how the permanent-point break-even period compares with the expected time on the loan, and what happens after an early payoff. Agency rules cited here are specific to the Fannie Mae and Freddie Mac contexts described in their guidance; consumer examples from Chase and LendingTree are illustrative rather than universal pricing. Your lender’s current written terms and applicable loan-program rules control your decision.

Frequently Asked Questions
Can a temporary buydown help me qualify for a larger mortgage?
Do not assume it will. Freddie Mac’s cited guidance for covered fixed-rate temporary buydowns calls for qualification using the note-rate payment, and the applicable rule depends on the loan program and lender.
Does a temporary buydown lower my APR?
The payment subsidy itself does not change the note rate, and the APR shown on a loan estimate reflects costs as well as the interest rate. Ask the lender to provide comparable written estimates; do not use the subsidized first-year payment as a substitute for comparing APR and fees.
Recommended Free Tools
What happens to a temporary buydown if I refinance?
A refinance pays off the existing mortgage, so the buydown agreement’s early-payoff provisions matter. Fannie Mae’s guide addresses how funds are disposed of and says they are not refundable unless payoff occurs before all funds have been applied; check the agreement for the specific treatment.
Can the seller pay for a mortgage buydown?
Fannie Mae’s delivery overview lists sellers among possible sources of temporary buydown funds, but permitted contributions and uses depend on the loan program. Ask your lender to confirm the rules and the proposed credit’s use in writing.
Is a 3-2-1 buydown always better than a 2-1 buydown?
No. A 3-2-1 schedule provides a longer subsidy but can require a larger funded account. Compare the total subsidy, every scheduled payment and the full note-rate payment rather than choosing by the label alone.
The Bottom Line
Bottom line: Choose permanent points when the quoted monthly savings recover the upfront cost before you realistically expect to pay off the loan. Choose a temporary buydown when early relief has real value, another party funds it on acceptable terms, and you can afford the full note-rate payment after the subsidy ends. Have the lender put both payment paths, all fees and early-payoff treatment in writing before you commit.
