Why we don’t push buydowns on refinances — and what the math says instead
When a lender can’t compete on price, the temporary buydown becomes the pitch — built to make a refinancing homeowner believe they’re paying less interest when they aren’t. Here’s the math we run on every refinance, why a lender credit usually does more with the same rate, and the one case where a buydown genuinely fits.
The refinance ‘buydown’ you’re being pitched
If you landed on this page because a lender or broker offered you a “buydown” on your refinance and something felt off — good instinct. Here’s exactly what’s being sold to you.
I’m seeing more lenders push temporary buydowns on refinances, often for a simple reason: they can’t compete on price, or they don’t have another tool, so the buydown becomes the thing they lead with. The pitch is built to make a homeowner believe they’re getting a lower rate and paying less interest.
They’re not. A temporary buydown is not a rate reduction. It’s a prepaid escrow account that lowers your payment for a year or two, then disappears, leaving the real note rate underneath the whole time. Your loan documents carry the full rate from day one.
And on a refinance specifically, one thing gets lost: on a purchase, a motivated seller or builder might actually fund the buydown. On a refinance, there’s no seller in the room — so the cost is built into the rate you’re quoted. You’re the one paying for it.
How we actually evaluate a refinance
We don’t lead with a product. We lead with the math — the same evaluation we run on every refinance. Nearly every refinance comes down to options priced off one lever: the rate.
- A lower rate with no lender credit. The lowest long-run cost. Best if you plan to keep this loan untouched for many years.
- A higher rate that generates an immediate lender credit — a rebate. Real value back at closing, in exchange for the higher rate.
Neither is automatically right. Which one wins depends on the numbers and on how long you’ll keep the loan — and you can run it on your own loan with our refinance buydown calculator. Once you see it laid out this way, the buydown stops looking like its own clever product and starts looking like what it actually is.
A buydown is just the higher-rate option in disguise
To pay for a buydown on a refinance, you have to accept a rate high enough to fund it. So if you want the buydown, you’ve already agreed to the higher rate. That isn’t a downside I’m sneaking past you — it’s baked into the buydown itself. The only real question left is what you get back for accepting that rate.
There are two ways to put that rate to work:
- The buydown way. The money is set aside in a temporary escrow account that lowers your payment for a year or two, then runs out. The benefit is released to you slowly, on a schedule, as reduced monthly payments — and it adds up to roughly the buydown’s cost.
- My way. I take that same rate and turn it into a lender credit. In my experience, that credit frequently lands at or above what the buydown would have cost — and instead of trickling out over two years, it goes to work on your loan now.
Where that credit actually goes
It typically doesn’t land in your account as a check at closing. In most cases it’s applied where it does the most good — toward your prepaid interest and your new escrow account. Done right, that’s what lets you skip your next mortgage payment, while your prior loan’s escrow balance still refunds back to you a few weeks after closing. And when the credit runs larger than those costs, the excess can go toward a principal curtailment that knocks down your balance, or in some cases come to you as cash at closing. Either way, the money is working for you now — not parceled out over the next two years.
And it can narrow your options to fewer lenders
Here’s something the pitch rarely mentions: not every lender offers temporary buydowns on refinances. So chasing one can quietly narrow you to a smaller set of lenders — and the only way to know whether that lender’s pricing is actually competitive is to compare it against others before you commit.
As a broker, I don’t work for one lender — I shop my entire lender network to find the most competitive pricing for your specific scenario, then structure the rate and credit around what you’re actually trying to do. A buydown shouldn’t be the thing that decides which lenders you even get to choose from.
Same rate, two very different deals
| Refinance buydown | Shop the network, take the credit | |
|---|---|---|
| The rate you accept | A higher rate to fund it | The same higher rate |
| What you get for it | About the buydown’s cost, released as lower payments over 1–2 years | A comparable credit, applied to your loan now |
| Which lenders offer it | A narrower set | Your full network, shopped for price |
| Where the benefit lands | A temporary escrow that ends after the teaser years | Prepaids, escrow, a skipped payment, or principal — yours now |
| How it’s sold to you | As a “lower rate” | As what it is: rate-versus-price math |
When the lower-rate option wins instead. If you truly plan to keep this loan for many years and never touch it, the lowest rate with no credit can cost you less over time — and I’ll show you that math too. But refinance clients tend to be rate-watchers. If there’s any real chance you refinance again or move, the credit usually comes out ahead. We run both numbers. The numbers decide — not the pitch.
When a refinance buydown might actually fit you
To be fair, a refinance buydown isn’t always the wrong call — and I’m not going to pretend it is. The honest exception is cash flow, and it comes down to form, not dollars.
A lender credit mostly helps you at closing: it covers prepaids, skips a payment, trims your principal. A buydown does something different — it lowers your actual monthly payment for the first year or two. For most people those are the same dollars in a different wrapper, which is why I usually steer toward the credit. But if you’re heading into a known, temporary income dip — a spouse taking unpaid leave, a business you’re getting off the ground, a single planned low-income year — sustained lower payments during exactly that window can be worth more to you than money at closing. In that specific case, the structure of a buydown fits the problem better than the math alone would suggest.
So the real answer isn’t “buydowns are bad.” It’s that for the large majority of refinances, the same rate does more for you as a credit — and the exception is when your need is breathing room in the monthly payment for a defined stretch. If that’s you, say so. It’s a legitimate reason, and it changes the recommendation.
If you’re buying
On a purchase, the same logic applies — with one caveat
If you’re buying rather than refinancing, the buydown has the same DNA. A 2-1 buydown isn’t a lower rate; it’s a prepaid escrow account that lowers your payment for a year or two before the real rate kicks in. The math only works if you stay long enough to actually use the subsidy — a 3-2-1 looks even better on the pitch sheet and burns even more if you refinance in year one or two.
The one real difference on a purchase: sometimes someone else is genuinely paying. A builder clearing inventory, a seller in a slow market, or an employer relocation package can make a buydown a reasonable move — if it’s truly their money and you’re confident you’ll stay through the period. But if it’s your money funding it, the same rule from the refinance side holds: shop the price, and put the credit to work where it helps you most.
The bottom line: shop the price, put the money to work now
Buyer or homeowner, the test is simple. When someone offers to lower your payment, ask two things: Is this the best price my full set of lenders can give me — and is the benefit working for me now, or drizzled out on someone else’s schedule? For most refinances, a buydown answers neither as well as simply taking the credit. The exception is a genuine, near-term cash-flow need — and if that’s your situation, it deserves to be on the table too.
That’s not a sales angle — it’s arithmetic, plus an honest look at your situation. If someone’s pitched you a buydown on your refinance, send me the numbers and I’ll show you every option side by side, including the one that actually fits what you’re trying to do.
