Almost every negotiation I run right now comes down to the same fork in the road. A home has sat on the market a while, the seller is ready to make a move, and their agent asks me: “Would your buyer rather have $10,000 off the price, or would a rate buydown work better?” Most buyers answer that question with a gut feeling instead of a calculator. I want to walk you through the actual math, because the two options are not equal, and which one wins depends on details most people never ask about.
Why This Question Is Everywhere Right Now
With roughly 3.6 months of housing supply across Maricopa County and homes averaging 73 days on market, sellers have real incentive to negotiate rather than let a listing go stale. More than half of recent Phoenix-area closings included some form of seller concession, and the two most common forms are a straight price cut or seller-funded help toward the buyer’s interest rate. Neither is automatically the better deal — it depends on your loan amount, how long you plan to stay in the home, and whether you need help qualifying today or saving money over time.
The $450,000 Example, With Real Numbers
Let’s use a realistic Phoenix purchase: a $450,000 home, 20% down, 30-year fixed loan, market rate around 6.75%.
Scenario A — $10,000 price reduction. The seller drops the price to $440,000. With 20% down, you finance $352,000 at 6.75%. Principal and interest come to about $2,284 per month.
Scenario B — $10,000 toward a permanent rate buydown (discount points). The price stays at $450,000, so you finance $360,000 — $8,000 more than in Scenario A. But that $10,000 seller credit buys roughly 2.5 discount points, dropping your rate from 6.75% to about 6.125%. Principal and interest come to about $2,188 per month.
Even though you’re borrowing $8,000 more in Scenario B, the lower rate wins — you pay about $96 less per month than the price-reduction path. Stay in the home the average 7-8 years, and that’s roughly $8,000-$9,000 in savings on top of what the price cut would have delivered, purely from the rate difference.
That result surprises most buyers. The lesson isn’t “buydowns always beat price cuts” — it’s that on a fixed budget, a permanent rate buydown is often more efficient than the same dollar amount knocked off the price, because interest compounds over the life of the loan while a price cut only saves you interest on that one increment of principal.
Permanent Buydown vs. Temporary 2-1 Buydown — They Are Not the Same Thing
This is where I see the most confusion. A permanent buydown (paying discount points) lowers your rate for the full 30 years. A 2-1 temporary buydown only reduces your rate for the first two years, then reverts to the full note rate for the remaining 28.
Using the same $360,000 loan at a 6.75% note rate, a 2-1 buydown would work like this: Year 1 the effective rate is 4.75%, payment around $1,878. Year 2 the effective rate is 5.75%, payment around $2,101. Year 3 onward, you’re paying the full note-rate payment of about $2,335. Funding that two-year subsidy costs the seller roughly $8,000-$8,500, held in an escrow account that pays down the difference each month.
A 2-1 buydown makes sense if you expect your income to rise, you plan to refinance once rates drop, or you just need breathing room while you settle in. It does not make sense if you’re planning to keep this loan long-term — you’d be paying nearly the same seller-funded amount as a permanent buydown but only getting two years of relief instead of thirty.
The Qualifying Trap Almost Nobody Tells You About
Here’s the detail that changes which option is actually right for you: most lenders underwrite a 2-1 temporary buydown using the full note rate, not the reduced first-year rate. That means a temporary buydown does nothing to help your debt-to-income ratio or your approved loan amount today — it only helps your cash flow after closing.
If you’re stretching to qualify, a temporary buydown won’t move the needle. What will: a price reduction (which directly lowers your loan amount and qualifying payment) or a permanent rate buydown via discount points (which lowers the rate lenders actually use to calculate your DTI). If your pre-approval is tight, ask your loan officer which of these three options — price cut, permanent buydown, or temporary buydown — actually changes your approved amount before you decide what to ask for in negotiations. If you haven’t nailed down the difference between pre-qualification and pre-approval yet, that’s worth doing before you’re mid-negotiation.
Why Sellers Often Prefer Buydowns Over Price Cuts
It’s not just about your payment — it affects the seller too, which is why you’ll often see a seller offer to fund a buydown before they’ll budge much on price. A recorded sale price becomes a comparable sale for every other home in the neighborhood for months afterward. A seller who cuts price by $10,000 sets a lower comp that their neighbors — and future buyers comparing homes — will see. A seller who instead pays $10,000 toward your rate keeps the recorded sale price at full value, and the cost shows up as a line-item concession instead of a lower sale price in public records.
That’s not a reason to accept a worse deal — the numbers above show a buydown can genuinely save you more. It’s just useful to understand why a seller’s agent will often steer the conversation toward buydowns first. For more on how these concessions get negotiated and where the caps are, see my breakdown of Phoenix seller concessions in 2026.
Loan-Type Limits You Need to Know
Whether you’re asking for points, closing cost help, or both, your loan program caps how much a seller can contribute:
- Conventional loans typically cap seller concessions at 3% of the purchase price with less than 10% down, up to 9% with 25%+ down.
- FHA loans cap seller concessions at 6% of the purchase price.
- VA loans cap seller concessions at 4% for certain costs, though points and some fees fall outside that cap depending on structure.
Discount points and price reductions are calculated differently against these caps, so before you decide which one to ask for, your lender needs to confirm exactly how much room you have left — especially if the seller is already covering some of your closing costs.
When a Price Reduction Is Actually the Better Ask
Run the other direction from a buydown when:
- Your DTI is tight and you need the loan amount itself to shrink, not just the rate.
- You’re worried about appraisal. A price reduction closes a value gap directly if the home was appraising light. A buydown does nothing for that problem.
- You expect to sell within a couple of years. A lower purchase price reduces your cost basis and the amount you need the home to appreciate to break even, whereas a buydown’s value erodes the moment you sell or refinance.
- You’re financing with a program that has a low concession cap, and points would eat room you need for closing costs instead.
When a Rate Buydown Wins
Ask for a buydown instead when:
- You’re planning to stay long-term. The longer the hold, the more a permanent rate reduction outperforms an equivalent price cut, as the math above shows.
- Your qualifying numbers already work fine, and you’re optimizing for monthly cash flow rather than approval.
- The seller is resistant to a lower sale price but open to funding closing costs or points — buydowns are often the path of least resistance to get a deal done at all.
The Bottom Line
There’s no universal right answer between a rate buydown and a price reduction — the math depends on your loan amount, how long you’ll keep the mortgage, and whether you’re trying to solve a qualifying problem or a long-term cost problem. In the $450,000 example above, a permanent buydown beat an equivalent price cut by roughly $96 a month, but a temporary 2-1 buydown wouldn’t have helped a tight approval at all. Before you tell a listing agent what to offer, run the actual numbers with your lender for your specific loan amount, rate environment, and program limits.
Frequently Asked Questions
Is a seller-paid rate buydown better than a price reduction in Phoenix?
It depends on how long you plan to keep the loan. In many cases a permanent buydown saves more over time than an equivalent price cut, because the rate reduction compounds over the life of the loan. If you plan to sell or refinance within a couple of years, a price reduction is usually more valuable.
Does a 2-1 buydown help me qualify for a larger loan?
No. Most lenders underwrite a temporary 2-1 buydown at the full note rate, not the reduced first-year rate, so it does not improve your debt-to-income ratio or approved loan amount. Only a permanent buydown (discount points) or a price reduction changes your qualifying numbers.
How many discount points can a seller pay toward my loan in Arizona?
It depends on your loan type and down payment. Conventional loans generally cap total seller concessions at 3-9% of the purchase price depending on your down payment, FHA caps at 6%, and VA has its own structure. Points count against these caps alongside any closing cost credits, so confirm your remaining room with your lender before negotiating.
