A mortgage rate buydown and a seller concession are not competing versions of the same thing: a buydown changes the cost of borrowing, while a seller concession is money the seller agrees to contribute toward eligible buyer costs. There is no universal winner. A permanent buydown may save more if you keep the loan long enough for the lower payments to recoup its upfront cost; a seller credit may matter more if cash to close is the main obstacle. Seller funds can also pay for points or an eligible temporary buydown, so the real choice is often how to use a limited contribution.
Compare written offers with the same loan terms, then weigh the savings over realistic time horizons against cash needs, purchase price, program rules, and the payment you can afford after any temporary subsidy ends.

| Name | Best for | Key tradeoff |
|---|---|---|
| Permanent rate buydown with discount points | Borrowers who can pay more upfront and expect to keep the mortgage long enough to benefit from a lower note rate | Higher upfront cost for a lower ongoing principal-and-interest payment; the time to recoup the cost depends on the actual loan offer |
| Temporary rate buydown | Eligible borrowers seeking lower payments for an initial period, with a plan and budget for the full payment | Early payment relief is temporary; the note rate and full contractual payment remain in place |
| Seller concession or credit | Buyers who need to reduce cash due at closing or want the seller to fund eligible costs | It may reduce closing cash without reducing the transaction’s total cost, especially if the purchase price rises in exchange |
What is the difference between a buydown and a seller concession?
A buydown is a way to pay for a lower mortgage rate or temporarily subsidize payments. A seller concession is a contribution toward eligible buyer costs. The first describes a financing outcome; the second describes who provides funds. They can be combined: a seller credit may pay for discount points or a temporary buydown if the loan program permits it.
Permanent buydown: pay points for a lower note rate
Discount points are an upfront charge in exchange for a lower interest rate. The Consumer Financial Protection Bureau (CFPB) explains that points trade upfront cost for a lower monthly payment. One point equals 1% of the loan amount, but the rate reduction for a point is not fixed: it varies by lender, loan type, and market conditions. Do not assume one point buys a particular rate reduction. The lender should show the points and their cost on the Loan Estimate and Closing Disclosure. See the CFPB’s guide to mortgage points and lender credits.

With a permanent buydown, the note rate is lower for the life of the loan. The borrower pays more at closing, then receives the benefit through a lower scheduled principal-and-interest payment and less interest over time, assuming the loan remains outstanding. The savings accumulate gradually. If the borrower sells, refinances, or pays off the loan before the savings have covered the upfront charge, the points may not have been worthwhile.
Temporary buydown: subsidize early payments, not the note rate
A temporary buydown uses funds from the seller or another acceptable party to subsidize some of the borrower’s early payments. The mortgage note keeps its contractual rate and payment terms; the subsidy makes the borrower’s effective payment lower for a limited period. When it ends, the borrower is responsible for the full payment under the note.

That distinction matters for both budgeting and qualification. Fannie Mae’s general rules for eligible temporary buydowns require qualifying at the note rate, not the introductory bought-down payment. Its guide allows a period of up to three years and limits the annual increase in the portion of the rate paid by the borrower to no more than 1%. These rules apply to eligible transactions and loan types, not every mortgage. The cited guide lists investment properties and cash-out refinances as ineligible for the described temporary buydown. Confirm eligibility with the lender and review Fannie Mae’s temporary-buydown requirements.
Seller concession: a contribution toward permitted costs
A seller concession, often called a seller credit, is a negotiated amount the seller contributes toward eligible buyer costs. Depending on the program and transaction, it can help cover closing costs, prepaid items, discount points, or an eligible temporary buydown. It generally reduces the buyer’s cash due at closing; it does not automatically lower the mortgage rate or the price of the home.

A credit also is not automatically a net financial gain. A seller might agree to contribute toward closing costs in exchange for a higher sale price. In that case, some or all of the apparent help at closing may be reflected in what the buyer pays for the home, and an inflated contract price can create appraisal or financing problems. The CFPB discusses this tradeoff in its explanation of loan costs and seller-paid closing costs. Compare the credit with the seller’s best price without it, rather than treating the credit as free money.
Which option saves more?
It depends on what “saves” means for your situation. A permanent buydown can reduce long-term borrowing costs if the loan lasts long enough. A seller concession can preserve cash at closing, and it can fund a buydown rather than compete with one. A temporary buydown can ease early payments but does not provide the same lasting payment reduction as a permanent rate change.
There is no defensible universal break-even period or savings figure. It depends on the loan amount, rate and point pricing, payment schedule, purchase price, fees, program rules, and how long you will keep the loan. Ask the lender to model actual options and state the assumptions. Use the comparison to answer three separate questions:
- How much cash do I need at closing? A seller credit toward eligible costs may help more than spending your own funds on points. Make sure the contribution can be used for the costs you intend to cover.
- How long am I likely to keep this mortgage? A permanent buydown needs time for the monthly savings to offset the added upfront cost. A sale, refinance, or payoff can end that opportunity early.
- Can I afford the full note payment? With a temporary buydown, budget for the contractual payment from the start. A lower initial payment is not evidence that the full payment is affordable.
If a seller is willing to contribute a fixed amount, the choice may be among using that money for eligible closing costs, permanent discount points, or a temporary subsidy. The right use depends on how much each option changes your cash due, payments, and total cost over your likely time in the loan. Compare the options rather than assuming that a rate reduction is always superior to keeping cash available.

How do you compare mortgage offers fairly?
Ask for written options that hold the important terms constant. The CFPB recommends comparing mortgage offers using the same choices across lenders; its mortgage-shopping guidance explains how to compare them. A low rate can be misleading if it comes with more points or different fees, and a large seller credit is not comparable if the purchase price or loan terms also change.
- Request matching Loan Estimates. Ask for offers with the same loan type, term, loan amount, down payment, and rate-lock assumptions. Request a zero-point option, an option with seller-paid points, and any eligible seller-paid closing-cost or temporary-buydown option. Keep lender fees and other terms visible rather than comparing only rates.
- Separate the upfront and ongoing effects. On each Loan Estimate, review the interest rate, points, monthly principal-and-interest payment, closing costs, credits, and estimated cash to close. A permanent buydown should show both its extra upfront cost and the resulting payment. A temporary buydown should show the subsidy period and what the borrower pays after it ends.
- Compare realistic time horizons. Ask the lender to show the costs and payments over a short, likely, and longer holding period. The point of these scenarios is not to predict exactly when you will move or refinance; it is to see how sensitive the outcome is to time in the loan. If the permanent-points option only comes out ahead after a period you are unlikely to keep the loan, it may be a poor fit.
- Compare the seller credit with the no-credit price. Ask what purchase price the seller would accept without the contribution. Consider whether the agreed price is supported by the appraisal and whether financing the higher price would increase your borrowing cost. A credit that lowers cash due may still be a useful liquidity choice, but distinguish that from a reduction in total cost.
- Verify program limits and allowed uses. Ask the lender how seller-paid points or buydown funds count under your specific loan program, occupancy, and transaction. Contribution limits, eligibility, and which costs qualify differ. An amount above a limit or above eligible costs may not be usable as you intended.
- Check the final disclosure. Compare the Closing Disclosure with your purchase agreement. Confirm the agreed seller-credit amount and verify that seller-paid costs appear as expected. The CFPB’s Closing Disclosure explainer describes where to review closing costs and credits.
For a simple permanent-buydown check, compare the added upfront points cost with the payment savings over the months you reasonably expect to keep the loan. That is only a screening method: a lender’s full comparison should account for the loan’s amortization and other costs, and you should not treat a break-even estimate as guaranteed savings. For a temporary buydown, compare the subsidy with the payment schedule and make sure the later full payment fits your budget. For a seller credit, compare the cash preserved at closing with any price increase and the program’s rules.
What seller-contribution limits apply?
The maximum and treatment of seller-paid costs depend on the mortgage program and transaction. These are program rules, not forecasts of consumer savings. The figures below come from the cited guidance; lenders may apply additional requirements, and the current rules and your case should be confirmed before relying on a limit.
Conventional loans under Fannie Mae guidance
Fannie Mae’s Interested Party Contributions guide sets maximum financing concessions according to occupancy and loan-to-value or combined loan-to-value (LTV/CLTV). For principal residences and second homes, the cited table lists a maximum of 3% when LTV/CLTV is above 90%, 6% at 75.01%–90%, and 9% at 75% or less. The listed maximum for investment-property transactions is 2%. The calculation uses the lower of the sales price or appraised value, and contributions cannot exceed the borrower’s closing costs. Interested-party-funded permanent and temporary buydown costs count in the contribution calculation. Contributions above the applicable maximum are treated as sales concessions and require the price and LTV treatment described in the guide. Review Fannie Mae’s current Interested Party Contributions requirements and have the lender confirm the applicable limit.

FHA Title II forward mortgages
HUD Handbook 4000.1, Update 17, revised November 26, 2025, says interested parties may contribute up to 6% of the sales price toward specified origination fees, closing costs, prepaid items, and discount points. That 6% limit includes permanent and temporary rate buydowns and listed payment supplements. The allowed amount and costs still need to be confirmed for the borrower’s FHA transaction with the lender. See HUD’s FHA Single Family Housing Policy Handbook, Update 17.
VA loans
VA guidance distinguishes credits for loan closing costs from seller concessions. VA does not limit credits for loan closing costs, while seller concessions are capped at 4% of the home’s reasonable value. Seller- or builder-funded temporary buydowns count as seller concessions. The borrower must qualify based on the full monthly payment after the subsidy ends. Buydown funds must be held in a separate escrow account and are subject to VA rules if the loan is paid off, foreclosed, or assumed. Do not treat the 4% seller-concession cap as a cap on every closing-cost credit. Check the VA’s pages on VA loan closing costs and temporary buydowns.
When does each choice make sense?
Use the purpose of the money and your likely time in the loan to narrow the decision, then verify the numbers with the lender.
- Consider a permanent buydown when you can cover the extra upfront cost without draining needed reserves, the offered rate reduction meaningfully lowers the payment, and your likely holding period is long enough for the savings to offset the cost. Compare the lender’s zero-point offer with the point-paid offer; do not assume a point is worth it just because the payment is lower.
- Consider a temporary buydown when you need short-term payment relief and can comfortably handle the full note payment when the subsidy expires. It should not be used to make an otherwise unaffordable mortgage appear affordable. Ask how the subsidy is funded and held, how the payment changes each year, and what happens under the program’s rules if the loan is paid off early.
- Prioritize seller-paid eligible costs when bringing the required cash to closing is the main constraint. This can keep your own funds available for reserves or other needs, but it does not necessarily reduce your overall cost. Confirm the price comparison, credit limit, and eligible costs.
- Ask for a lower purchase price as a separate alternative when the seller is negotiating on price as well as credits. A lower price may change the loan amount and financing costs; a seller credit changes who pays certain eligible costs. The lender can provide a same-terms comparison so you can see the different effects.
Negotiating is worth asking about, but the contract and lender rules determine what can actually be applied. As the CFPB puts it, “Negotiation is common, and there’s no harm in asking.” Treat the seller’s proposed contribution as one part of the offer, not as a substitute for comparing the price and financing.

What should you confirm before closing?
Before accepting a credit or buydown, make sure the negotiated arrangement is reflected consistently in the contract and final loan documents. Ask the lender to confirm the following in writing:
- Which exact costs the seller contribution can cover, and whether points or the chosen buydown are eligible.
- The applicable contribution limit for the loan program, occupancy, LTV/CLTV, and transaction—and whether any part of the contribution exceeds that limit or eligible costs.
- The amount of cash to close under each option, including the effect of points, credits, and any changed purchase price.
- For a permanent buydown, the rate, points charge, monthly principal-and-interest payment, and lender’s comparison over the time horizons you requested.
- For a temporary buydown, the full note payment, each subsidized payment period, the payment when the subsidy ends, and the funding and escrow arrangements required by the program.
- That the seller-credit amount and seller-paid line items on the Closing Disclosure match the purchase agreement and approved loan terms.
If the final disclosure differs from what you agreed, ask the lender and settlement agent to explain the discrepancy before signing. A seller contribution is most useful when it is allowed, documented, and applied to the cost you actually intended to reduce.

Can a seller credit pay for discount points?
Often it can, if the loan program permits the expense and the contribution stays within the applicable limit and eligible closing costs. Ask the lender to show the points and seller-paid amount on the written estimate and confirm how they count under your program.
Do mortgage points lower my monthly payment forever?
Points generally buy a lower note rate for the mortgage, but the payment benefit lasts only while that loan remains outstanding. Selling, refinancing, or paying off the mortgage ends the opportunity to collect future monthly savings.
What happens to a temporary buydown if I sell or refinance early?
The answer depends on the loan program and the buydown agreement; funds held for the subsidy may be subject to program-specific rules. Ask the lender how unused funds are handled in a payoff, refinance, assumption, or foreclosure scenario before agreeing.
Can I receive unused seller-credit money as cash?
Do not assume so. Seller contributions are generally constrained by the program’s rules and eligible costs, and a contribution cannot necessarily be converted into cash paid to the buyer. Have the lender identify the eligible costs and any amount that could not be applied.
