Temporary vs. Permanent Rate Buydowns: Which One Actually Saves You Money?

A temporary buydown lowers your payment for the first year or two; a permanent buydown — discount points — lowers your rate for the life of the loan. Which one saves you money comes down to two questions: who is paying for it, and how long you will actually keep the loan. A seller-funded temporary buydown is a real win, because someone else prepays part of your payment. A buyer-funded one is mostly you handing yourself your own money back. Points only pay off if you hold the loan past break-even. Here is the honest math on all of it.

One ground rule before the numbers: every dollar figure and rate in this article is illustrative — not a quote, not today’s pricing. Buydown costs and point pricing move with the market daily, so treat everything here as general and confirm current pricing before you decide. If you’re just getting oriented, our Homebuyer 101 primer on rate buydowns covers the vocabulary in five minutes.

How a temporary buydown actually works

A temporary buydown reduces your effective payment for a set period at the start of the loan. The two common flavors:

• 2-1 buydown: your payment is calculated as if the rate were 2% lower in year one and 1% lower in year two. Year three onward, you pay the full note rate.
• 1-0 buydown: 1% lower in year one only.

Here’s the part most marketing skips: your actual rate never changes. You sign a note at the full rate, and a lump sum deposited at closing sits in an escrow account, covering the gap between your subsidized payment and the real one each month. Fannie Mae’s Selling Guide requires the buydown funds to sit in a custodial account and requires lenders to qualify you at the full note rate, not the teaser payment. The same guide caps the structure: the rate can’t be bought down more than 3%, the buydown can’t run longer than three years, and the borrower’s rate can’t step up more than 1% per year.

An illustrative example. Take a $400,000 30-year loan at an illustrative 7% note rate — principal and interest of about $2,661 per month. With a 2-1 buydown:

• Year one is calculated at 5%: about $2,147 per month, saving roughly $514 a month, or about $6,168 for the year.
• Year two is calculated at 6%: about $2,398 per month, saving roughly $263 a month, or about $3,156 for the year.
• Total buydown cost: about $9,324 — which is exactly the sum of the savings.

That last line is the whole game. A temporary buydown’s cost equals its benefit, dollar for dollar. It is not a discount; it is a prepaid subsidy. Nobody is giving you anything — the only question is whose dollars fund the escrow account. If you want to see the year-by-year payment schedule in more detail, we walk through a full 2-1 buydown example step by step. You can run your own numbers with our temporary buydown calculator before you negotiate.

The real question: who pays for it

Because cost equals savings, the entire value of a temporary buydown depends on who funds it.

• Seller- or builder-funded: a genuine win. If the seller deposits $9,324 into your buydown escrow, that is $9,324 of your first two years’ payments made by someone else. In our illustrative example, that’s real money you keep.
• Buyer-funded: mostly pointless. If you fund it yourself, you’re prepaying your own mortgage payments through an escrow account — and you still had to qualify at the full note rate anyway. The same cash would usually work harder as a price negotiation, a bigger down payment, or discount points.

Buydown money coming from the seller counts as part of your seller concessions, and those are capped. Under Fannie Mae’s interested-party contribution limits, financing concessions on a primary residence are capped at 3%, 6%, or 9% of the lower of the sales price or appraised value, depending on your down payment size — and the guide explicitly counts temporary and permanent buydown subsidies toward that cap. So a big buydown can crowd out other credits, like the seller paying your closing costs.

Locally, builder-funded buydowns show up most often in El Paso County’s new-construction corridors — think Banning Lewis Ranch, Meridian Ranch, or Lorson Ranch — where builders would rather advertise a lower first-year payment than cut the base price and reset their comps. That can still be a fine deal for you; just price it against the alternative. If you want a second set of eyes on a builder’s buydown offer, talk with a Colorado Springs mortgage broker who can price the alternative.

Our take: a buyer-funded temporary buydown almost never makes sense. If the money is yours, negotiate the price down or buy the rate down permanently instead. If the money is the seller’s or builder’s, take it — that’s the version that actually saves you money.

How permanent buydowns (discount points) work

Discount points are the opposite trade: you pay more cash at closing for a lower rate that lasts as long as the loan does. The CFPB’s rule of thumb is simple: one point costs 1% of your loan amount and buys a lower rate than the zero-point option at the same lender. How much lower varies with the market and the lender — there is no fixed exchange rate, so treat any “one point buys a quarter percent” shorthand as general and confirm current pricing on the day you lock.

Illustrative example, same $400,000 loan: one point costs $4,000. Suppose it lowers the illustrative rate from 7% to 6.75%. Principal and interest drops from about $2,661 to about $2,594 — a savings of roughly $67 per month, every month, for as long as you keep the loan.

Unlike the temporary version, this is a real repricing of your debt. But it is also a bet: you’re paying a known cost today for savings that only materialize over time.

Temporary vs. permanent, side by side

The structural differences drive everything else. A temporary buydown changes your payment in years one and two only, is usually funded by a seller or builder credit, and leaves you qualifying at the full note rate. Points change the rate for the life of the loan, are usually paid by the buyer in cash at closing, and you qualify at the bought-down rate. And if you refinance, unused temporary-buydown funds typically get credited against the payoff — while money spent on points is simply spent.

The break-even math, done honestly

For points, the core test is one division problem: point cost divided by monthly savings equals your break-even in months. In our illustrative example, $4,000 ÷ $67 is about 60 months — five years. Keep the loan longer than five years and the points were a good buy; exit sooner and you paid for savings you never collected.

Doing this honestly means a few things:

1. Compare same-day quotes. A zero-point rate from Tuesday against a one-point rate from Friday tells you nothing — the market moved in between.
2. Compare the same structure. Points versus no points at the same lender, same lock period, same loan. The honest way to run this comparison is the same method we lay out in how to compare mortgage offers: same day, same lender-credit structure, line by line.
3. Be honest about your timeline. The CFPB’s guidance is to run the math over several timeframes — the shortest, longest, and most likely time you’d keep the loan. Most buyers overestimate how long they’ll hold a mortgage. Job changes, growing families, and refinances all shorten the clock.

One more honesty check: simple break-even ignores what else your $4,000 could do. If that cash would otherwise raise your down payment enough to shrink mortgage insurance, or sit in reserves you actually need, the true break-even is longer than the division problem suggests.

The refinance caveat: a refi ends both — differently

People buy points at higher-rate moments precisely when a future refinance is most tempting — which is exactly when points are most likely to be wasted. If rates fall and you refinance in year two, you never reach the 60-month break-even. The $4,000 is gone; points are a sunk cost the moment you close.

A temporary buydown fails more gently. Under Fannie Mae’s rules, if the mortgage is paid off early, remaining buydown funds are generally credited against the payoff — or returned as the buydown agreement specifies. So a refinance doesn’t torch the leftover subsidy — but it does end the below-note payment schedule, and if the seller funded it, the leftover credit is the tail end of a benefit you were getting anyway. Either way, buydown pricing gets set when you lock, so it helps to understand how rate locks work before you’re under contract.

When each one wins

Temporary buydown wins when:

• The seller or builder funds it — someone else’s money covering your payments is the one unambiguous win in this article.
• You expect your income to rise into the full payment, or you think a refinance is plausible within a few years.
• Concession room exists that would otherwise go unused under the contribution caps.

Permanent buydown wins when:

• You’ll confidently hold the loan well past break-even — in our illustrative case, comfortably beyond five years.
• You don’t expect rates to fall enough to make refinancing attractive during that window.
• Paying the points doesn’t drain the cash you need for reserves, moving, or the inevitable first-year house surprises.

Our take: the honest hierarchy is seller-funded temporary buydown first (someone else’s money beats yours), points second (only with a long, realistic timeline), buyer-funded temporary buydown last (it’s your own money in a costume). And if a lender pitches a buydown without showing you the zero-point, no-buydown alternative side by side, ask for it. The comparison is the product.

Frequently asked questions

Is a 2-1 buydown free money? Only if someone else funds it. The buydown’s cost equals its savings dollar for dollar, so a seller- or builder-funded buydown is a genuine transfer to you, while a buyer-funded one is you prepaying your own payments through an escrow account.

Do I qualify for the loan at the lower buydown payment? No. Fannie Mae requires lenders to qualify you at the full note rate, not the temporarily reduced payment. The buydown eases your early payments; it does not stretch your approval.

What happens to buydown funds if I sell or refinance early? Under Fannie Mae’s guidelines, remaining buydown funds are generally credited against your loan payoff when the mortgage is paid off early, or returned as the buydown agreement specifies. You don’t typically forfeit the unused subsidy, but the discounted payment schedule ends with the loan.

How much does one discount point cost, and how much does it lower my rate? One point costs 1% of your loan amount — $4,000 on a $400,000 loan. How much rate it buys varies with market conditions and the lender; there’s no fixed formula, so compare same-day quotes with and without points and confirm current pricing.

Can the seller pay for my discount points instead of a temporary buydown? Yes. Seller-paid points are a permanent rate reduction funded with the seller’s money, and many buyers prefer that to a two-year subsidy. Both count toward the interested-party contribution caps — 3%, 6%, or 9% of the lower of the sales price or appraised value on a primary residence, depending on your down payment.
