Short answer: A seller credit can lower your cash to close or fund a rate buydown, while a price reduction changes the loan balance. On a $500,000 purchase, the same $10,000 negotiation can have very different effects. The right choice depends on the lender's quote, the loan program, how long you expect to keep the loan, and whether the full payment works after any temporary buydown ends.
The payment is the decision
My advice in this market is simple: stop waiting for a number and start building around a payment.[3] A rate headline cannot tell you what your home costs each month. Your lender has to combine the price, down payment, credit profile, loan type, points, taxes, insurance, and HOA dues.
The seller's side matters too. ARMLS reported that 75% of Phoenix-area single-family homes sold below their original list price in July 2026.[1] Gilbert, Chandler, and Mesa were closing near 98% of list in Redfin's August rolling figures.[4] That creates room on the right listing, but you still have to decide what to ask for.
Rates right now
Freddie Mac reported a 6.76% national average for a 30-year fixed mortgage and 6.09% for a 15-year fixed as of September 10, 2026.[2] Those are national averages based on qualifying applications, not a quote for you. Freddie Mac also notes that shopping multiple lenders can save borrowers money.[2]
A permanent buydown uses upfront money to reduce the note rate for the life of the loan. A temporary buydown uses money held for scheduled payment assistance during the first one, two, or three years. The note rate does not change in a temporary buydown, and Fannie Mae requires qualification at the full note rate for loans it purchases.[5] Your lender must confirm the rules for your loan.
A $500,000 Chandler example
Here is a simple illustration, not a lender quote. Assume a $500,000 purchase, 20% down, a $400,000 30-year fixed loan, and a 6.76% note rate. The principal and interest payment is about $2,597 per month. Taxes, insurance, HOA dues, closing costs, and prepaid items are not included.
| Scenario | Illustrated payment | Difference |
|---|---|---|
| No concession | $2,597 per month | Baseline |
| $10,000 price reduction | $2,545 per month | About $52 less each month |
| 2-1 buydown year 1 at 4.76% | $2,089 per month | About $508 less each month |
| 2-1 buydown year 2 at 5.76% | $2,337 per month | About $260 less each month |
| 2-1 buydown year 3 and later | $2,597 per month | Returns to the full note-rate payment |
Illustration assumes a $400,000 loan amortized over 30 years. The estimated subsidy for the two discounted years is about $9,219. Actual rates, buydown cost, seller credit limits, fees, and qualification rules come from the lender and loan program.
The $10,000 price reduction takes the purchase price to $490,000. With 20% down, the loan falls to $392,000, which reduces principal and interest by about $52 a month at the same rate. That savings lasts for the loan, but it is smaller than many buyers expect.
In the illustrated 2-1 buydown, the first-year payment is calculated at 4.76%, the second year at 5.76%, and the payment returns to the 6.76% note-rate amount in year three. The estimated subsidy is about $9,219. A $10,000 seller credit could cover that amount if the lender and loan rules allow it, with any permitted remainder applied to other eligible costs. Seller-funded buydowns count toward interested-party contribution limits.[5][6]
When a permanent buydown makes sense
Ask the lender for the exact cost to lower the rate and the monthly savings. Then divide the upfront cost by the monthly savings. That is the simple break-even period. If the permanent buydown costs $8,000 and saves $100 a month, the break-even point is 80 months. If you expect to sell or refinance sooner, using the credit for closing costs may leave you in a better position.
Do not assume one point always lowers the rate by a fixed amount. A point equals 1% of the loan amount, but the rate improvement changes with the lender, the day, the loan, and the borrower. Get the price and rate in writing for the same moment before comparing options.[6]
When a temporary buydown makes sense
A temporary buydown can help when you expect income to rise, you want more room for moving costs during the first year, or the seller is willing to fund the subsidy. The danger is treating the discounted payment as the real payment. In the example, the payment rises about $248 from year one to year two, then about $260 from year two to year three.
If the year-three payment does not work today, the buydown does not fix the purchase. A future refinance may happen, but it is not guaranteed. The home should make sense at the full note-rate payment before you rely on temporary savings.
When closing costs are the better use
Cash is often the real constraint. A buyer may have the income for the payment but still need reserves after the down payment, inspection, appraisal, prepaid taxes, insurance, and moving expenses. Using a seller credit for allowed closing costs can preserve cash for repairs and emergencies. That may be more valuable than a small monthly reduction.
Ask the lender for three side-by-side estimates: a price reduction, a permanent buydown, and a temporary buydown or closing-cost credit. Keep the purchase price, down payment, loan type, and lock timing the same. Otherwise you are comparing different loans and calling the concession the reason.
How to ask without weakening the offer
Target listings where the request fits the facts. Look for days on market beyond the city median, a price reduction, a vacant home, or a property that returned to market. Those signals do not guarantee a credit, but they give the seller a reason to trade money for certainty.
Show strong financing and keep the request clean. State the credit as a dollar amount or contract percentage that fits the loan rules. Let the seller see the net. On a fresh, correctly priced home with competition, you may need to cover the buydown yourself or raise the price enough to preserve the seller's acceptable net, subject to appraisal.
When a credit is not the right move
Do not ask for more than you can use. Do not raise the price to create a credit unless the home can appraise and the payment still works. Do not spend thousands on a permanent buydown without calculating break-even. And do not use a temporary buydown to hide a payment that becomes unaffordable in year three.

What to do this week
Send your lender one realistic listing and ask for the four numbers that matter: payment with no credit, payment with a price reduction, payment and cost for a permanent buydown, and the full schedule for a temporary buydown. Then I can match the offer to the listing and show the seller a clean reason to say yes.

Frequently Asked Questions
What is a seller credit?
A seller credit is money the seller agrees to contribute toward eligible buyer costs at closing. The contract, loan program, appraisal, and actual closing costs limit how it can be used. Unused credit generally does not become cash back to the buyer.
Is a seller credit better than a price reduction?
It depends on the buyer's constraint. In the $500,000 illustration, a $10,000 price reduction lowers principal and interest by about $52 a month. A credit may have a larger near-term effect when used for an eligible buydown or may preserve cash when used for closing costs.
How does a 2-1 mortgage buydown work?
A 2-1 buydown provides scheduled payment assistance for two years. The payment is calculated two percentage points below the note rate in year one and one point below in year two, then returns to the full note-rate payment in year three. The note rate itself does not change.
Can I qualify using the temporary buydown payment?
Qualification rules depend on the loan program and lender, and many loans require qualification at the full note-rate payment. Ask the lender before writing the offer. The full payment should fit your budget even if the temporary payment is lower.
How much seller credit can I request in Arizona?
The limit depends on the loan type, down payment, occupancy, appraisal, and the buyer's eligible closing costs. A contract can request a number, but the lender determines how much the loan permits and how much can actually be used. Get that limit before negotiating.
