Rate Buydowns: The Same $10,000, Four Different Ways
You negotiated $10,000 out of the seller. Congratulations; that was the easy part. Now comes the decision almost nobody makes deliberately: what should that money actually DO? Cut the price? Cover your closing costs? Buy down your rate permanently? Fund one of those 2-1 buydowns every builder advertises?
Same ten thousand dollars. Four completely different outcomes for your monthly payment, your cash at closing, and your five-year cost of owning the home. This page runs the exact math on all four, side by side, on the same loan, so you can see what each choice is really worth.
A note on who wrote this
I'm Nick Peters (NMLS #1119524), a loan originator with 12+ years of experience. Every number on this page is computed exactly on one consistent example loan, and every number is illustrative: rates move daily, and buydown pricing is a live market. Use this page to understand the structures and compare the shapes. Use your lender, after your rate is locked, for your real numbers.
The decision nobody makes deliberately
Here's the pattern I see constantly. A buyer and their agent fight hard for a seller credit, and then the credit gets deployed by default: whatever the listing agent suggested, whatever the builder was already advertising, or simply "toward closing costs" because that's the path of least paperwork. The negotiation gets all the attention. The deployment, which often matters more, gets none.
The reason deployment matters: a dollar of seller money is not worth the same amount in every slot. Spent one way, $10,000 returns about $3,800 of payment relief over five years. Spent another way, it returns nearly $9,500 and keeps paying past year five. Spent a third way, it delivers almost $500 a month of relief right now, when you need it most, and nothing after year two. None of these is wrong. They're different tools, and the right one depends on your cash position, your timeline, and what the next three years of your income look like.
The example loan (read this before the numbers)
Every figure below uses one frozen scenario so the four options compare honestly:
$400,000 purchase price. 5% down. $380,000 loan. 30-year fixed. 7.00% note rate. $10,000 of seller money on the table.
At 7.00%, the principal-and-interest payment on this loan is $2,528 a month. That's the baseline every option gets measured against. The 7.00% is an illustrative round number, not a quote, not an offer, and not a prediction; your rate will be whatever the market and your file say on the day you lock. The relationships between the four options hold at any rate in the neighborhood, which is what matters here.
Option one: take it off the price
The default move, and the weakest one for your monthly payment. A $10,000 price reduction takes the price to $390,000; with the same 5% down structure, your loan drops to $370,500 and your payment drops to $2,465 a month. You save $63 a month, plus $500 less down payment at closing.
Why so little? Because a price cut spreads the $10,000 across 360 payments with interest math working against the drama. The value isn't gone; it's parked. You owe $9,500 less, you have a slightly bigger equity cushion, and over the full 30 years the cut returns its value. But as monthly relief, it's the smallest lever on this page by a wide margin.
When the price cut genuinely wins: when the appraisal is the risk. The concession caps you read about on the seller concessions page run on the lesser of price or appraised value, and an aggressive price with a big credit stacked on top is exactly the shape that makes appraisals nervous. Cutting the price lowers the bar the appraisal has to clear. If you're in a soft market or the comps are thin, the boring option is sometimes the safe one. The other honest case for it: you've already covered your costs, you don't need payment relief, and you simply want to owe less.
Option two: cover your closing costs
The cash-flow move. On a $400,000 purchase, closing costs and prepaids typically run somewhere in the 2% to 4% range. A $10,000 credit aimed here doesn't change your payment at all; it changes the check you write at closing, dollar for dollar. Payment stays $2,528. Cash to close drops $10,000.
For a lot of buyers, this isn't one option among four; it's the mandatory first stop. If covering costs is the difference between draining your savings and keeping a real emergency fund after you get the keys, take the cash relief and don't look back. A lower payment is worthless if you're house-poor on day one. This is also the order of operations I walk through on the seller concessions page: cover what you actually owe first, then deploy whatever's left.
Two rules keep this option honest. The credit can't exceed your actual closing costs and prepaids; negotiate $10,000 against $8,000 of real costs and the extra $2,000 doesn't become cash back, it evaporates or has to be restructured. And the credit counts toward your program's concession cap, which on this example loan (5% down, conventional) is 3% of the price: $12,000. The $10,000 fits. Barely. That's not an accident in this example; it's a reminder to check the cap before you write the offer.
Option three: buy the rate down permanently (discount points)
The long-game move. Discount points are prepaid interest: each point costs 1% of the loan amount and permanently lowers your rate. How much rate a point buys changes with the market, sometimes daily. A useful conservative planning number is about 0.25% of rate per point, with diminishing returns as you stack them; some days pricing is better than that, some days worse. This is the number you must confirm with your lender after your rate is locked, because buydown pricing is a live market and any figure printed on a page (including this one) is a planning assumption, not a quote.
On the example loan: $10,000 buys 2.63 points ($10,000 against a $380,000 loan). At the conservative 0.25%-per-point assumption, that's roughly 0.66% of rate, taking 7.00% down to about 6.375% after rounding to the eighth lenders actually price in. New payment: $2,371 a month. You save $157 a month, every month, for the life of the loan. Five-year value: about $9,447. Ten-year value: nearly $19,000. If you keep the loan long enough, this option laps every other one on this page.
The catch is the word "if." Permanent buydown value accrues slowly and only while you keep the loan. Refinance or sell in year two and most of the value never arrives. The classic mistake of 2021 was buyers paying points and refinancing eight months later; the classic mistake of the high-rate era is the reverse, buyers skipping points while planning to stay put for a decade. Match the tool to your actual timeline, not to the market mood.
Option four: the 2-1 temporary buydown
The front-loaded move, and the one every builder billboard is selling. A 2-1 buydown doesn't change your note rate at all. Your rate is still 7.00% and your loan documents say so. What the seller's money actually buys is a subsidy account: funds sit in a protected escrow at the lender, and each month for two years, that account pays the difference between your reduced payment and the real one.
The schedule on the example loan: Year one, you pay as if the rate were 5.00%: $2,040 a month, saving $488 a month. Year two, as if 6.00%: $2,278, saving $250 a month. Year three through thirty: the full $2,528. The step-up is capped at 1% of rate per year by guideline, which is why the shapes are 2-1 and 3-2-1 and not anything steeper.
What it costs: exactly the sum of the subsidies. Twelve payments of $488 plus twelve of $250 comes to $8,857. Notice that's less than the $10,000 on the table, which means this option has a bonus move: fund the full 2-1 AND put the leftover $1,143 toward closing costs. On this loan, $10,000 covers both.
Three mechanics worth knowing before you sign one. First, you qualify at the full note rate; the lender underwrites you as if the $2,528 payment starts on day one, which is the guideline protecting you from a payment you can't actually afford (more on that in a moment). Second, if you refinance, sell, or pay off the loan during the buydown period, the remaining escrow funds don't vanish; they're credited, typically against your payoff. Third, a 2-1 is not an ARM: an ARM's rate genuinely changes with the market, while a 2-1's rate never changes at all; only the subsidy does. People conflate these constantly and they are nothing alike in risk.
When the 2-1 genuinely fits: real, dated income growth. A resident finishing training, a spouse returning to work next year, a contractual step raise. You're using the seller's money to bridge to an income that is actually coming. It can also fit when the cash-flow squeeze of a move (furniture, repairs, the overlap month of rent and mortgage) is concentrated in year one and you want the relief concentrated there too.
The comparison grid
| Comparison | Price Cut | Closing Costs | Permanent Points | 2-1 Buydown |
|---|---|---|---|---|
| Monthly payment effect | Saves $63/mo | No change | Saves $157/mo, permanent | Saves $488/mo yr 1, $250/mo yr 2 |
| Cash at closing effect | Down payment drops $500 | Cash to close drops $10,000 | No change | Leftover $1,143 to costs |
| Five-year value returned | $3,792 relief + $9,500 less owed | $10,000, all on day one | $9,447 and still going | $8,857, all in 24 months |
| Effect on qualifying | Slightly smaller loan | None | Qualify at the LOWER rate | Qualify at the FULL rate |
| Watch out for | Weak monthly relief | The actual-cost ceiling | Timeline risk + live pricing | The year-three step-up |
| Criterion | Price Cut | Closing Costs | Permanent Points | 2-1 Buydown |
|---|---|---|---|---|
| Monthly payment effect | Saves $63/mo. Loan drops to $370,500; payment drops to $2,465. The smallest monthly lever on the page because the value spreads across 360 payments. | No change. Payment stays $2,528. This option trades monthly relief for day-one cash relief. | Saves $157/mo, permanent. Rate drops from 7.00% to roughly 6.375% (conservative 0.25% per point assumption; confirm real pricing with your lender after lock). Payment drops to $2,371 for the life of the loan. | Saves $488/mo yr 1, $250/mo yr 2. Year one paid as if 5.00% ($2,040); year two as if 6.00% ($2,278); full $2,528 from year three on. Note rate never changes; an escrow subsidy covers the difference. |
| Cash at closing effect | Down payment drops $500. 5% of a $10,000 lower price. Modest, but real. | Cash to close drops $10,000. Dollar-for-dollar relief, capped at your actual costs and prepaids. Credit beyond actual costs evaporates; size the ask to the real number. | No change. The credit pays the points; your down payment and costs are unaffected. | Leftover $1,143 to costs. The 2-1 costs $8,857 on this loan, so a $10,000 credit funds the full buydown with $1,143 remaining for closing costs. |
| Five-year value returned | $3,792 relief + $9,500 less owed. Sixty months at $63. The rest of the value is stored as a smaller balance, not delivered as cash flow. | $10,000, all on day one. No ongoing relief, but the full credit lands immediately as cash you didn't spend. | $9,447 and still going. Best long-run option on the page. Crosses the 2-1's total around year three and never stops accruing. | $8,857, all in 24 months. Maximum early relief, zero after year two. Wins if your squeeze (or your income gap) lives in the first two years. |
| Effect on qualifying | Slightly smaller loan. Marginally lower payment helps DTI a little. Rarely decisive. | None. Qualifying payment unchanged. | Qualify at the LOWER rate. The bought-down rate IS the note rate, so underwriting uses the reduced payment. The only option here that meaningfully shrinks DTI; can turn a marginal file into an approval. | Qualify at the FULL rate. Fannie, FHA, and VA all require qualifying at the note rate, not the bought-down payment. The year-one payment helps your budget, not your approval. |
| Watch out for | Weak monthly relief. Don't take it by default. Its honest use cases: appraisal risk, or wanting a smaller balance after costs are already handled. It's also the only option that consumes none of your concession cap. | The actual-cost ceiling. Credits can't exceed what you really owe. Get the lender's cash-to-close number BEFORE setting the ask, and check the program's concession cap (3% on this example loan). | Timeline risk + live pricing. Refinance or sell early and the value never accrues. Point pricing changes daily with diminishing returns when stacking; the 0.25%-per-point figure is a planning assumption, never a quote. | The year-three step-up. Make sure today's income covers the full payment comfortably; a buydown should make two years cheaper, not make an unaffordable home look affordable. Refund of unused escrow on refi or sale is the consolation, not the plan. Seller-funded buydowns also count toward concession caps. |
The five-year scoreboard
Same $10,000, measured by what it hands back in the first five years on the example loan:
Price cut: $3,792 of payment relief ($63 × 60 months), plus a $9,500 smaller balance working quietly in the background.
Closing costs: $0 of monthly relief, but $10,000 of cash that never left your savings on day one.
Permanent points: $9,447 of payment relief, still going at month 61 and every month after.
2-1 buydown: $8,857 of relief, all of it delivered in the first 24 months, plus the $1,143 leftover toward costs.
Read the scoreboard honestly and three things jump out. Every option except the price cut returns roughly the full $10,000 of value within five years; they differ in WHEN and in WHAT FORM. The price cut returns the least relief because most of its value is stored as balance reduction, not delivered as cash flow. And the 2-1 versus points question is really a question about time: the 2-1 wins years one and two decisively, points win year four onward, and year three is roughly the crossover on this loan. Your timeline picks your winner.
Which one should you actually pick
There's no universal answer, but there is a clean decision path, and it's the one I walk with clients:
Start with cash. If covering closing costs is the difference between a funded emergency account and an empty one, costs come first. Always. Whatever remains after real costs are covered is the money the rest of this decision is about.
Then check the qualifying math. If your approval is tight, permanent points are the only option here that lowers your qualifying payment. That can decide the whole question before preference enters into it.
Then match the tool to your timeline. Staying seven-plus years with comfortable qualifying: permanent points compound the longest. Real, dated income growth arriving within two years: the 2-1 puts the relief exactly where the squeeze is. Soft market, nervous comps, appraisal risk: the price cut earns its keep by protecting the deal itself.
Then check the cap. Every deployment except the price cut counts toward your program's concession limit, and that includes seller-funded buydowns, both kinds. On a 5% down conventional loan the cap is 3%; FHA allows 6%; VA splits costs and concessions into different buckets; the full breakdown is on the seller concessions page. The price cut is the release valve: it consumes no cap at all, which is why big incentives sometimes split (cap-limited credit plus price reduction for the remainder).
And one instruction that outranks all of it: get your lender's actual buydown pricing after your rate is locked, before you finalize the deployment. The 0.25%-per-point figure on this page is a deliberately conservative planning assumption. Real pricing moves every day, and the difference between a planning number and a locked number is the difference between this page and your deal.
What I see in real files
The default deployment. The most common pattern isn't a wrong choice; it's no choice. The credit lands "toward closing costs" by inertia, even when costs were already covered and the remainder evaporates against the actual-cost ceiling. Ten minutes of deployment math before the offer would have moved real money.
The builder special, unexamined. Builders advertise the 2-1 because the year-one payment makes the marketing. Sometimes it's genuinely the right structure. But on the same incentive dollars, I've shown buyers a permanent buydown that beat the 2-1 by year three and never expired. The advertised structure is the builder's choice. It doesn't have to be yours.
The refinance assumption doing load-bearing work. Files where the buyer is comfortable at the year-one payment, strained at the real one, and the plan is "rates will be lower by then." Qualifying at the note rate exists precisely because of these files. When the guideline feels like an obstacle, it's usually being a guardrail.
The points-as-rescue surprise. The happiest version of this page in practice: a tight-DTI file where shifting the seller credit from costs to permanent points dropped the qualifying payment enough to approve cleanly. The buyer thought they were buying a payment. They were actually buying the approval.
The cap collision. A 6% credit negotiated on a 5% down conventional contract, discovered against the 3% cap in underwriting. The fix was a restructure: part credit, part price reduction. It closed, but the renegotiation cost goodwill that better sequencing would have kept.
Where this gets you
Seller money is only as good as its deployment. The same $10,000 can be $63 a month, $157 a month, $488 a month for a year, or $10,000 of day-one cash, and the seller is indifferent between every version. The choice is entirely yours, it's worth real money, and it takes one conversation with your lender to make deliberately instead of by default.
