Rate Buydowns and Price Cuts: Comparing Scenarios
When a seller offers a rate buydown or a price concession, the question is how the two change your actual payment, now and later. Temporary buydowns fund lower early payments; permanent buydowns pay points to lower the rate for life; price cuts shrink the loan itself. This guide shows how to compare them with fully disclosed assumptions.

The direct answer
A temporary buydown (commonly a 2-1 or 3-2-1) uses up-front subsidy funds to lower the monthly payment for the first one to three years, with the note rate and loan balance unchanged and the payment resetting afterward. A permanent buydown uses discount points to reduce the note rate for the life of the loan. A price cut reduces the loan amount itself, permanently lowering principal and interest. These are different machines with different costs and timelines, and the honest comparison is a payment stream with every assumption disclosed.
Key takeaways
- Temporary and permanent buydowns are different products. A temporary buydown funds a payment subsidy for the first one to three years without changing the note rate or balance; a permanent buydown pays discount points to lower the note rate for the life of the loan.
- Compare the whole payment stream. A price cut lowers principal and interest for the full term; a temporary buydown lowers only the early years, and the payment resets to the note rate afterward.
- Every illustration needs its assumptions disclosed: date, price, down payment, loan type and term, rate assumptions, fees, payment components, and the reset periods. No assumptions, no comparison.
- Principal and interest is not the total payment. Taxes, insurance, and HOA fees sit on top, and APR is a different number from the note rate, so both belong in the disclosure.
- Program limits apply. Fannie Mae and FHA both define what temporary buydowns can do, and eligibility, concession limits, and qualification math vary by loan program and lender.
- There is no universal winner and no guaranteed approval or savings. Buydowns are negotiated tools with costs, and their fit depends on your rate, price, cash, and how long you expect to hold the loan, without assuming a refinance.
What is a temporary buydown, exactly?
A temporary buydown (2-1 lowers the rate by 2 points in year one and 1 point in year two; 3-2-1 steps down three, two, and one) works through a buydown account: the seller or lender funds a lump sum that releases monthly to reduce the payment during the buydown term. The note rate and the loan balance do not change, the payment resets to the note rate after the term ends, and the borrower remains responsible for the full payment if the buydown funds are ever unavailable.
Under Fannie Mae's current selling guide, temporary buydowns are permitted on fixed-rate loans and certain ARMs for principal residences and second homes, with a maximum rate reduction of 3 percentage points across no more than three years and annual step-ups of no more than 1 point. FHA guidance describes temporary buydowns with its own qualification math. These are the rules your lender operates inside, and the buydown agreement states the exact structure you are getting.
What is a permanent buydown, and how is it different?
A permanent buydown exchanges cash at closing for a lower note rate for the entire loan term. The instrument is the discount point, commonly described as about 1 percent of the loan amount per point, with the exact rate reduction depending on the lender's pricing at that moment. One point does not equal one percentage point of rate; the relationship changes with market conditions, and the lender's rate sheet is the source.
The CFPB's consumer guidance describes the tradeoff plainly: paying points up front buys a lower payment for the life of the loan, and the break-even depends on how long you keep the loan. A permanent buydown changes the note rate; a temporary buydown changes early payments only. The two are often combined in a seller's concession package, which makes the loan estimate and the buydown agreement required reading.
What does a price cut change that neither buydown does?
A price cut reduces the purchase price, which reduces the loan amount at the same down payment percentage, which permanently lowers principal and interest, and it may change the loan-to-value ratio, the private mortgage insurance picture, and the property tax basis (taxes are assessed separately by the county). Its effect is smaller per dollar than a buydown's early-year effect, but it lasts for the full loan term. That permanence is the structural difference.
An illustrative scenario, with every assumption disclosed
Illustration assumptions and date
Illustrative example only, not a quote or a commitment. Assumes a purchase price of $500,000, a 20 percent down payment of $100,000, a 30-year fixed-rate loan of $400,000, a base note rate of 6.5 percent, and a date of October 8, 2026. Figures are rounded principal-and-interest (P&I) estimates before taxes, insurance, HOA fees, and any fees or points, which appear on the Loan Estimate.
Scenario A: 2-1 temporary buydown of 50 basis points of rate value
A funded buydown lowers the effective payment rate to approximately 4.5 percent in year one, 5.5 percent in year two, and the note rate of 6.5 percent from year three on. Estimated P&I: about $2,027 per month in year one, about $2,271 in year two, and about $2,528 from year three for the remaining term. The note rate and balance never change; the payment resets at year three.
Scenario B: $5,000 price reduction
A $5,000 price cut to $495,000 with the same 20 percent down payment lowers the loan to about $396,000 at the same 6.5 percent note rate. Estimated P&I: about $2,503 per month for the full 30-year term, roughly $25 per month below Scenario A's year-three payment, with no reset and a permanently lower balance.
The read is not "which is bigger" but "which shape fits": Scenario A buys the biggest early reduction, concentrated in years one and two. Scenario B buys a smaller, permanent reduction. In real numbers, the size of any seller concession, the buydown structure, the points, and the actual rate available on your date take these illustrations and replace them with your figures. The payment components on every estimate are principal and interest only; the total payment adds taxes, insurance, and HOA, and the APR reflects the full cost of credit, both of which appear on the Loan Estimate for the loan you actually choose.
What are the eligibility and limit questions to ask?
Program limits shape every buydown. Fannie Mae's rules cap temporary buydown structure and scope as described above, and seller concessions are governed by the interested-party contribution limits that apply to the loan program. FHA guidance defines its own buydown treatment and qualification math. The lender's underwriting, credit, and program rules are the ones that decide what your deal can include, and the mortgagee's written guidance is what your lender applies. This article states no concession limit because the applicable figure depends on the loan program, the transaction, and the current source guidance, which your lender verifies from the source documents.
What is the honest comparison framework?
Compare scenarios on four lines: the payment in each year before any reset, the payment after the reset, the cash required at closing, and the total interest over the assumed holding period. No comparison that stops at the first-year payment is complete, and no comparison that assumes a refinance is honest unless the refinance is a documented plan with current terms. A buydown is a negotiated tool with a cost; a price cut is a change to the loan itself. Which one fits is a numbers question, answered with your figures, by your lender, on your date.
Frequently asked questions
Should I take the buydown or negotiate a lower price instead?
That depends on numbers only you and your lender can produce, but the shape of the answer is predictable. A price reduction cuts principal and interest permanently but modestly at the same rate; a buydown cuts the early payments sharply and temporarily, then resets. If you expect to hold the loan past the reset, the price cut keeps helping; if the early payments are the constraint, the buydown targets exactly that. Model both with your actual figures, not someone else's illustration.
Does a buydown change the loan amount or the note rate?
A temporary buydown changes neither: the note rate and the loan balance stay as agreed, and the buydown account releases funds monthly to reduce the payment for its term. A permanent buydown changes the note rate itself, usually through discount points paid at closing. The loan estimate and the buydown agreement state which structure you actually have.
Are buydowns limited to certain loans or buyers?
Yes. Fannie Mae's temporary buydown rules apply to fixed-rate loans and some ARMs for principal residences and second homes, with limits on how much the rate can be reduced and how quickly it steps back up. FHA guidance allows temporary buydowns with specific qualification math. Conforming limits, credit, and lender overlays apply to every borrower, so eligibility is confirmed through your lender, not assumed from an article.

Educational note: the illustration is a rounded estimate with dated assumptions, not a quote, a rate lock, an approval, or a savings claim. Principal and interest differ from the total payment and from APR; no refinance is assumed; and no scenario is presented as universally best. Run your own numbers with your lender before making any decision.
