2-1 Temporary Rate Buydown or $9,425 Off the Price Instead? The Real 5-Year Cost on a $400,000 Loan

A production builder offering "9,425 dollars toward your rate" and a builder offering "9,425 dollars off the price" are offering the same money and two different outcomes. Which one is worth more over five years turns entirely on five pieces of vocabulary that the sales sheet uses loosely: the note rate, the buydown escrow, how the 9,425 figure is produced, what counts as equity when the purchase price itself moves, and the return you would need to earn for the cash-flow option to win. Define those five and the comparison stops being a matter of opinion.

Key takeaways

  • Freddie Mac's Primary Mortgage Market Survey put the 30-year fixed average at 7.18% as of November 5, 2026 (third consecutive weekly decline; 7.24% the prior week, 6.22% a year earlier; 15-year 6.57%). The worked example below is built on the 7.24% week of October 29, 2026, the week this kind of offer was priced, and is kept at that rate so every figure ties out.
  • On a 400,000 dollar loan at 7.24%, funding a standard 2-1 buydown costs 9,424.55 dollars. Spending the same amount as a permanent price cut takes the loan to 390,575 dollars and the payment from 2,725.99 to 2,661.76 dollars, 64.23 dollars a month for 30 years.
  • Over five years the buydown leaves 5,570.68 dollars more cash in hand and 8,894.28 dollars more debt outstanding. But the price-cut buyer also owns a house that cost 9,425 dollars less, so calling that debt gap "more equity" is only correct if the concession was money the buyer would have overpaid.
  • Invest the monthly difference and the buydown's five-year advantage is 7,890 dollars at a 7% return, not the 7,200 dollars this piece first published. The return needed to beat the price cut on the debt-gap framing is about 9.6% a year.
  • The 15-basis-point rate markup Freddie Mac measured on buydown loans is worth 40.80 dollars a month on this loan, not 23 dollars, and it cuts the buydown's five-year advantage at 7% from 7,890 to about 5,070 dollars.

Figures checked: November 7, 2026.

Three terms that set the price

Note rate

Definition. The interest rate written on the promissory note. It is the rate the loan amortizes at for its entire term, and a temporary buydown does not change it.

The calculation. At 7.24% on 400,000 dollars over 360 months, the principal-and-interest payment is 2,725.99 dollars. That payment is what the amortization schedule runs on from month one, including the two years when the buyer hands over less than that.

The trap. Because the note rate is unchanged, the loan balance falls on exactly the same schedule as a loan with no buydown at all. Five years in, the balance is 377,476.22 dollars either way. Nothing about the buydown builds equity; it only moves who writes the check in years one and two.

The temporary buydown escrow

Definition. A funded account, paid upfront by the builder, seller or buyer, that pays the lender the difference between the buyer's reduced payment and the full note payment for a set number of years. In a 2-1 structure the buyer's effective rate is two percentage points below the note rate in year one and one point below in year two.

The calculation. Year one runs at 5.24%, which on a 400,000 dollar, 30-year schedule is a 2,206.34 dollar payment, 519.65 dollars below full. Year two runs at 6.24%, a 2,460.27 dollar payment, 265.72 dollars below full. From month 25 the buyer pays 2,725.99 dollars for the remaining 25 years.

The trap. Two separate rules follow from the escrow being an escrow rather than a rate. Freddie Mac requires lenders to qualify the borrower at the full note rate, not the year-one rate, so the structure cannot stretch a buyer into a larger loan. And if the loan is paid off early, unused subsidy is typically applied to the balance or forfeited depending on the program, so selling or refinancing in year one or two throws away most of what the incentive was worth.

The 9,425 dollars

Definition. Not a price the builder picked. It is the sum of the payments the escrow has to make: 24 months of covering the gap between the buyer's reduced payment and the note payment.

The calculation. 519.65 times 12 is 6,235.86 dollars. 265.72 times 12 is 3,188.70 dollars. Together, 9,424.55 dollars. That is the entire cost of the incentive, which is why the same money is exactly comparable to a 9,425 dollar price reduction. Any version of this article that said the incentive was 9,400 dollars was rounding the funding cost, not quoting a separate offer.

The trap. The funding cost scales with the note rate, so it is not a fixed menu item. At a higher note rate the same 2-1 structure costs more to fund, which means the "equivalent" price cut a buyer should demand instead is larger too. Ask for the funding amount in writing rather than assuming a round number.

Two terms that decide the winner

Equity, when the purchase price itself moves

Definition. Equity is the value of the house minus the debt against it. Both halves matter, and a price reduction changes both halves at once: it cuts the loan by 9,425 dollars and it cuts what was paid for the house by the same 9,425 dollars.

The calculation. After five years the buydown buyer owes 377,476.22 dollars and the price-cut buyer owes 368,581.93 dollars, a gap of 8,894.28 dollars. But the price-cut buyer's house was bought for 9,425 dollars less. Measured against purchase price, the buydown buyer is actually ahead on equity by 530.72 dollars, not behind by 8,894 dollars.

The trap. This is where the original version of this article went wrong, and it is worth being explicit about which assumption produces which answer:

  • If the list price was fair and the concession genuinely reduces what the buyer gets for the money, then the price cut buys a cheaper house, the two buyers hold nearly identical equity, and the buydown's cash-flow advantage decides it. On this reading the buydown is ahead by 6,101.40 dollars over five years before investing a cent.
  • If the list price was above market and the concession is money the buyer would otherwise have overpaid, which is the common situation at production-builder communities that hold list prices and discount through incentives, then the house is worth the same either way and the 8,894.28 dollar debt gap is real equity. On this reading the price cut is ahead by 3,323.60 dollars over five years.

Nobody can tell a buyer which of those two worlds they are in from the brochure. An appraisal and recent closed comparable sales in the same community can, and that is a cheaper piece of research than either incentive is worth.

Break-even return

Definition. The annual return the buyer would have to earn on the buydown's extra cash flow for the buydown to match the price cut. It is the honest way to state the choice, because the buydown's advantage is a cash-flow advantage and cash flow is only worth something if it is put to work.

The calculation. Relative to the price-cut path, the buydown buyer keeps 455.42 dollars a month in year one and 201.49 dollars a month in year two, then pays 64.23 dollars a month more for years three through five. Invested at the end of each month, that differential stream is worth:

Assumed annual returnValue of the cash-flow difference at year 5Verdict if the list price was fairVerdict if the concession avoided overpaying
0% (spent, not invested)5,570.68Buydown ahead 6,101.40Price cut ahead 3,323.60

10%9,059.00Buydown ahead 9,589.72Buydown ahead 164.72

Assumptions: all figures in US dollars on a 400,000 dollar loan at the 7.24% note rate of the week of October 29, 2026, 30-year amortization, principal and interest only; taxes, insurance, mortgage insurance and closing costs are identical on both paths and left out; the monthly differential is invested at month end and compounded monthly at the annual rate shown; no taxes on investment gains; the buyer keeps the loan the whole five years. The returns in the left column are assumptions chosen to span a range, not forecasts, and this piece no longer cites a "historical stock-market average" because no single such figure applies to a five-year holding period.

The trap. On the second framing, the break-even is about 9.6% a year, every year, for five years, with no missed months. That is the number a buyer should hold the sales pitch against. My own read: a buyer who is confident they will automate the transfer and leave it alone should take the cash flow; a buyer who knows the extra 455 dollars will be absorbed by furniture and a fence should take the price cut, because at a 0% return the price cut wins by 3,324 dollars on the framing that actually applies at most builder communities.

The five-year ledger, and the markup the brochure leaves out

With the vocabulary settled, the two paths side by side are short enough to put in one table.

 Option A: 2-1 buydown on 400,000Option B: 9,425 off the price, 390,575 financed
Note rate7.24%7.24%
Payment, year 12,206.342,661.76
Payment, year 22,460.272,661.76
Payment, years 3 to 302,725.992,661.76
Principal and interest paid over 5 years154,135.00159,705.68
Balance after 5 years377,476.22368,581.93
Purchase price relative to the other path9,425 higher9,425 lower

Read across the bottom three rows and the whole argument is visible. Option A pays 5,570.68 dollars less cash and owes 8,894.28 dollars more, and Option B owns a house that cost 9,425 dollars less. Which of the last two lines you treat as real is the question the sales office will not answer for you.

Two findings from Freddie Mac's research division change the arithmetic rather than just adding colour. The first is the qualification rule already covered above. The second is a price: in the period Freddie Mac studied, June 2022 through June 2023, borrowers who took a temporary buydown received note rates about 15 basis points higher on average than borrowers who did not, because originators can price the cost of the structure into the permanent rate instead of charging all of it upfront.

That 15 basis points is not a rounding error on this loan, and the figure previously published here understated it. At 7.39% instead of 7.24%, the 400,000 dollar payment is 2,766.79 dollars, 40.80 dollars a month more, which over 30 years is 14,687 dollars. Reworking the whole comparison at a 7.39% note rate, with the 2-1 structure buying the payment down to 5.39% and 6.39%:

  • Funding the buydown now costs 9,486.60 dollars rather than 9,424.55.
  • The buydown buyer keeps 418.13 dollars a month in year one and 162.36 in year two, then pays 105.03 dollars a month more than the price-cut buyer from month 25 on, not 64.23.
  • The five-year cash-flow difference falls to 3,185 dollars uninvested and about 5,068 dollars at a 7% return, against a debt gap that widens to 9,471.94 dollars.

In other words, a buyer who accepts a 15-basis-point markup to get the buydown gives back roughly a third of the cash-flow advantage the structure was supposed to deliver, and loses on the debt-gap framing at any plausible return. This is the single most useful question in the whole exercise, and it is a question, not a calculation: what note rate would you give us without the buydown?

Two further cautions that no table captures. The Federal Housing Finance Agency's Office of Inspector General, which oversees Fannie Mae and Freddie Mac, has flagged that buydown loans tend to carry riskier characteristics overall, including higher loan-to-value ratios, and specifically warns about payment shock when the full payment arrives in year three. And Freddie Mac describes temporary buydowns as a niche product, concentrated among non-bank lenders and more common in some Western states, so structure and availability vary by lender and builder and a real offer will not match these figures dollar for dollar.

What to ask before signing

  1. Is the incentive available as a price reduction if we decline the rate buydown, and what is the exact dollar figure in each form? Ask for the buydown's funding amount in writing; it is a calculated number, not a round one.
  2. What note rate would we be offered without the buydown structure? If the answer is more than a few basis points below the buydown quote, price that difference as a monthly payment before deciding, because 15 basis points is worth 40.80 dollars a month on a 400,000 dollar loan.
  3. Will the lender confirm in writing that qualification is based on the full note-rate payment rather than the year-one payment?
  4. What happens to unused escrow funds if we sell or refinance in year one or two? Get the program's specific treatment, not a general answer.
  5. Have recent closed sales in this community been at list price or below? That is what decides whether the price cut is real equity or just a cheaper house.
  6. If we take the buydown, will the monthly difference be moved into an account automatically on payment day? At a 0% return the buydown loses on the framing that applies at most builder communities, so the transfer is the whole case for it.

This article is general information, not individualized financial, tax, or legal advice, and it is not a personalized recommendation. Mortgage rates, program availability and underwriting rules change and vary by lender, loan type and state; all figures are US dollars for a conventional 30-year fixed loan and were checked on November 7, 2026. Confirm current terms with a licensed loan officer, and consider a fee-only financial planner before choosing between a temporary buydown and a permanent price reduction on a specific loan.

FAQ

Is a 2-1 buydown or a price reduction better on a 400,000 dollar loan?

It depends on two things, not one. If the builder's list price was fair, the buydown is ahead by 6,101 dollars over five years even with the cash spent rather than invested, because the price-cut buyer simply bought a cheaper house. If the concession is money you would otherwise have overpaid, the price cut is ahead by 3,324 dollars at a 0% return, and the buydown only catches up at a sustained return of about 9.6% a year.

How much does a 2-1 buydown cost on a 400,000 dollar loan?

At the 7.24% note rate of the week of October 29, 2026, 9,424.55 dollars, paid upfront into an escrow account by the builder, seller or buyer. The figure is the sum of 12 monthly gaps of 519.65 dollars in year one and 12 of 265.72 dollars in year two, so it moves with the note rate rather than being a fixed package price.

Does a 2-1 buydown change my actual mortgage rate?

No. The note rate stays at the full rate for all 30 years and the loan amortizes on the full payment, so the balance after five years is 377,476.22 dollars whether or not the buydown is there. The escrow only subsidizes what you hand over in years one and two.

Does taking a buydown affect the rate I am offered?

It can. Freddie Mac found that over June 2022 to June 2023, borrowers who used a temporary buydown received note rates about 15 basis points higher on average. On a 400,000 dollar loan that is 40.80 dollars a month and 14,687 dollars over 30 years, and it cuts the buydown's five-year advantage at a 7% return from about 7,890 dollars to about 5,068 dollars.

Do I still have to qualify at the full rate?

Yes. Lenders must qualify the borrower using the full note rate rather than the discounted year-one rate, so a temporary buydown cannot be used to qualify for a larger loan than you could otherwise afford.

What happens to the buydown money if I sell or refinance early?

Unused subsidy in the escrow account is typically applied to the loan balance or forfeited, depending on the program, and the remaining discounted payments are lost. Because most of a 2-1 structure's value sits in the first 24 months, an exit in year one or two throws away most of the incentive. A price reduction has no such cutoff: it is already in the loan balance.

What is the current average 30-year mortgage rate?

Freddie Mac's Primary Mortgage Market Survey put the 30-year fixed average at 7.18% as of November 5, 2026, down from 7.24% the prior week and a third consecutive weekly decline; the 15-year average was 6.57%, and the 30-year stood at 6.22% a year earlier. The worked example above is kept at 7.24% so that every figure in it ties out.

Tip: Running the buydown and the price-cut scenarios side by side is far easier on paper than in your head.

(These are Amazon Associate links — we may earn a small commission on qualifying purchases.)

Correction November 7, 2026: three figures in the original version were wrong. First, the five-year comparison treated the 8,894.28 dollar difference in loan balances as "more home equity" for the price-cut path without accounting for that path's 9,425 dollar lower purchase price; measured against purchase price the buydown path is ahead on equity by 530.72 dollars, and the article now states both framings and the assumption each rests on. Second, the invested cash-flow advantage at a 7% return is 7,890 dollars, not the 7,200 dollars originally published, and the two component figures have been recomputed as 10,446 and 2,556 dollars; the unsourced "historical stock-market average" has been replaced with a labelled range of assumed returns and a break-even return of about 9.6% a year. Third, a 15-basis-point rate markup on this loan adds 40.80 dollars a month, not roughly 23 dollars. The incentive amount has also been made consistently 9,424.55 dollars rather than 9,400 in some places, and the current Freddie Mac survey reading has been added.

Is a HELOC Cheaper Than a Fixed Home Equity Loan for a $40,000 Renovation?

Image
A homeowner planning a $40,000 renovation usually checks one number first: which loan has the lower rate today. Right now that is the home equity line of credit, not the fixed-rate home equity loan. But a HELOC's rate is variable for the full repayment period, while a fixed home equity loan locks in today's rate for the life of the loan. Financed over 10 years, that difference can flip the real cost in either direction. So the honest way to read the comparison is not "which rate is lower" but "what is the one number that separates them actually made of." That number is $3,256.70, and the rest of this post takes it apart. Photo: Celestin bonaventure, Wikimedia Commons , CC BY-SA 4.0 — generic illustrative renovation photo, not tied to the specific loan figures below. Key takeaways As of November 4, 2026, the national average HELOC rate is 7.49%, versus 8.77% for a 10-year fixed home equity loan, per Bankrate's lender survey. On a $40,000, 10-year...

Car Loan or Mortgage First? What a 1.25-Point Rate Gap Actually Costs Over 5 Years

Image
A household has a $350,000 mortgage balance at today's going rate and a $28,000 car loan, and $300 a month they could put toward either one. The instinct for a lot of people is to attack the car loan first — it's the smaller balance, it feels winnable, and being "debt-free" on the car sooner has an obvious appeal. The math says something different, and the gap between the intuitive answer and the correct one is worth walking through with real numbers, because the size of that gap depends entirely on the interest rates involved — and in this specific case, it's smaller than you'd expect.

80/10/10 Piggyback Loan or Monthly PMI? The Real 5-Year Cost on a $400,000 Home With 10% Down

On a $400,000 home with 10% down, splitting the financing into an 80/10/10 piggyback loan comes out about $29,000 ahead of taking one 90%-loan-to-value mortgage and paying monthly private mortgage insurance (PMI) over the first five years, in the worked example below.

Should You Assume a Seller's 3.25% FHA Loan, or Take a New One at 7.18%? The Real 5-Year Cost

Image
Correction November 11, 2026: The rate gap between the assumed 3.25% FHA loan and the 7.18% new-loan rate was given as roughly 394 basis points; 7.18% minus 3.25% is 393 basis points. The paragraph on approval risk also stated FHA’s underwriting thresholds as a flat “580 or higher” score and “43% or lower” debt-to-income; HUD publishes the manual-underwriting limits as a grid (31%/43% with no compensating factors, 37%/47% with one, 40%/50% with two), and that passage has been rewritten to match. Source: HUD FHA Resource Center, maximum qualifying ratios for manually underwritten loans, updated October 8, 2026. A seller's FHA mortgage rarely comes up in a home search, but it should.

15-Year Mortgage or 30-Year Plus Investing the Difference? The Real 10-Year Net-Worth Comparison on a $350,000 Loan

Balance Transfer or Personal Loan to Pay Off $8,000 in Credit Card Debt: Which Costs Less?

Image
To pay off $8,000 in credit card debt, a 0% balance transfer card usually costs less than a personal loan, but only if the monthly payment stays high. At a steady $376.21 a month, a transfer with a 4% fee and a 15-month promotional period costs about $542 in fees and interest, a 24-month personal loan at 11.90% costs about $1,029, and leaving the balance on a card charging 22.36% costs about $2,283. Drop the payment to $200 a month and the same transfer costs about $2,415, more than double the loan. Credit cards in a wallet (file photo). Photo: Chris Potter, Wikimedia Commons , CC BY 2.0 Key takeaways On an $8,000 balance paid at $376.21 a month, the 0% transfer (4% fee, 15 months) costs about $542, the 24-month loan at 11.90% about $1,029, and the original 22.36% card about $2,283.

What's a Good Homeowners Insurance Deductible? The Real 10-Year Cost of $500 vs. $2,500

Image
Correction November 8, 2026: the one-claim comparison had the $500 deductible subtracted twice. The net 10-year position for the $2,500 deductible with one claim is +$2,620 (not +$3,120), and the gap between the two deductibles in that case is $3,120 (not $3,620). The underlying inputs — $512 a year in premium savings, $5,120 over 10 years, and a $2,000 difference in out-of-pocket cost per claim — are unchanged, as is the two-claim result and the 2.56-claim break-even.

Is a No-Closing-Cost Refinance Really Free? The Real Break-Even on a $350,000 Loan

Image
A no-closing-cost refinance is not free, and it is also not the worst of the options on the table. Those costs — title, appraisal, recording, underwriting — still exist and still get paid; what changes is whether they leave your bank account at closing, get buried in a higher rate, or get added to the loan balance. Those are three different prices for the same thing, and on a $350,000 refinance they do not rank the way the marketing or the usual advice suggests. What follows puts all three side by side at this week's rates, finds the month each one overtakes the others, and then shows how little of that answer depends on the rate level and how much depends on two numbers a lender will quote you in a single phone call.
