A rate buydown lowers your mortgage interest rate by paying points up front. Here's how permanent and temporary buydowns work, who pays, and how ~$15,000 in transaction savings can fund one.
A rate buydown is paying money up front, usually through mortgage discount points, to lower your interest rate. You can buy the rate down permanently for the life of the loan or temporarily for the first few years, and the cost can be covered by you, the seller, a builder, or your lender.
If you're waiting for mortgage rates to drop before you buy, you've got company. Thirty-year fixed rates are sitting around 6.65% in late August 2026, and plenty of would-be buyers have decided to wait it out until that number moves. Trouble is, nobody controls when it moves, or whether it will. And you don't have to wait on it anyway. You can lower the rate you actually pay right now, using money that usually vanishes into an agent's commission.
Waiting feels like the safe move. Usually it isn't.
Start with the obvious problem: nobody can tell you when rates will fall, or if they will. The people who forecast this for a living get it wrong constantly. "I'll buy when rates hit 5%" sounds like a plan, but it's pinned to a number you can't schedule.
Then there's the cost of sitting still. You're paying rent the whole time you wait, and in a lot of markets prices keep grinding higher. Wait a year for a rate that may never show up, and a higher price plus a bigger down payment can swallow whatever you thought you were going to save.
It feels high because it isn't 3%. But 3% was the fluke, not the rule.
Freddie Mac has tracked the 30-year fixed since 1971. Over that stretch it has averaged about 7.7%, with a median of 7.23%. Today's 6.65% actually sits under that long-run average.
Look at the extremes and it gets clearer. The rate topped out at 18.63% in October 1981 and bottomed at 2.65% in January 2021. The midpoint of that range would be somewhere near 10.6%, so 6.65% isn't the middle of anything. It's just a little below normal.
| 30-year fixed rate | |
|---|---|
| All-time high (Oct 1981) | 18.63% |
| Long-run average (since 1971) | ~7.7% |
| Today (Aug 2026) | ~6.65% |
| All-time low (Jan 2021) | 2.65% |
Those sub-4% years in the 2010s and 2021 didn't happen by accident. They came out of the 2008 crash and then the pandemic, two emergencies the economy hasn't repeated on command. Waiting for rates like that to return isn't waiting for normal. It's waiting for the next disaster. The one piece of this you can actually control today is your rate, and that's what a buydown does.
A buydown just means paying something up front to knock down your interest rate. The mechanism is called a discount point.
One point costs 1% of the loan and usually shaves about 0.25% off your rate. On a $400,000 loan, that's $4,000 for a point. How much each point moves the rate depends on the lender and the market, some do 0.20%, some do 0.30%, so treat the numbers below as an example, not a quote.
There are two flavors, and they fix different problems.
A permanent buydown drops your rate for the whole life of the loan. You pay the points at closing and the lower rate rides all 30 years. This is the one you want if you're planning to stay put.
A temporary buydown only lowers the rate for the first year or two before it climbs back to full. The common versions are the "2-1" (2% lower in year one, 1% lower in year two, then full rate after) and the "3-2-1." They're paid for with money parked in an escrow account that covers the gap early on. A temporary buydown fits if you're betting on refinancing later, or you just want some room to breathe at the start.
Neither one wins across the board. Permanent buydowns pay off when you keep the loan a long time. Temporary ones make sense when you expect things to change soon.
The money for a buydown has to come from somewhere, and it isn't always the buyer's wallet.
The best buydown is the one you don't pay for yourself. That's where the cost of the transaction comes back into it.
Most people never connect these two things. The biggest cost you can actually control in a home purchase is the real estate commission, and shrinking it puts real money on the table, money that can go straight into a buydown. The transaction you have to do anyway to get the house is the thing that pays for your lower rate. That's the whole point of buying or selling through VroomBrick: one flat fee instead of a full commission, and the gap turns into buying power you can aim at your rate.
VroomBrick runs on a flat 1% technology fee instead of the usual 3% agent commission. In 2026 we've saved our members roughly $15,000 per transaction on average, based on our own closings this year. That money can go one of two directions:
Take that ~$15,000 and put it toward points on a $400,000, 30-year fixed loan. At about $4,000 a point, you're buying roughly 3.75 points, which works out to close to 0.9% off the rate under the usual rule of thumb.
| Traditional (no buydown) | ~$15,000 applied as a permanent buydown | |
|---|---|---|
| Illustrative interest rate | ~6.65% | ~5.75% |
| Monthly principal & interest ($400K loan) | ~$2,568 | ~$2,335 |
| Monthly difference | (baseline) | ~$233 less |
| Over the life of the loan (30 years) | (baseline) | ~$84,000 less in total payments |
And because that buydown got paid for out of transaction savings instead of fresh cash from your account, the ~$233 a month and ~$84,000 over the loan cost you basically nothing up front.
These numbers are illustrative. One point is 1% of the loan and typically lowers the rate about 0.25%, but the real reduction depends on your lender, credit, loan type, and the market, and the lifetime figure assumes you keep the loan the full 30 years. Mortgage rates change daily. Whether transaction savings can be applied to a buydown, and how large a buydown or seller concession a loan program allows, depends on your loan type and lender, conventional, FHA, and VA loans each cap seller-paid costs differently.

Run your own numbers with a licensed lender before deciding.
It comes down to how long you keep the loan. Every buydown has a break-even point, the month where your savings finally pass what you paid for the points. For most buyers that lands somewhere in the four-to-eight-year range.
Stay past break-even and a permanent buydown comes out ahead. Sell or refinance before it, and a temporary buydown, or skipping the buydown entirely, usually makes more sense. If you're really banking on rates easing so you can refinance, a temporary buydown gives you a lower payment now and keeps that door open. If you'd rather stop guessing and just lock in a lower rate, the permanent version does that today without needing a forecast to cooperate. Either way, this is a tool for making a house you're already buying easier to carry month to month. It's not a reason to reach past what you can afford.
Run the numbers before you commit, because whether a buydown pays off usually comes down to nothing more than your own timeline.
Paying money up front, usually as discount points, to lower your interest rate. One point costs 1% of the loan and typically drops the rate about 0.25%, though it varies by lender.
A permanent buydown lasts the life of the loan. A temporary one, like a 2-1, only lowers the rate for the first year or two before it returns to full, and it is funded from an escrow account.
The buyer, the seller (as a concession), a builder (as an incentive), or the lender (as a credit for a higher rate). Loan programs cap how much a seller or builder can contribute, and the cap varies by loan type and down payment.
It depends on how long you keep the loan. Most buydowns break even in four to eight years, so a permanent buydown pays off if you stay past that, while a temporary one fits if you expect to sell or refinance sooner.
You can keep waiting on the Fed, or you can work with the part you actually control. Start with what the transaction costs, since that's the money funding everything else. Run your home value through the savings calculator to see the gap between a traditional 3% commission and VroomBrick's 1% technology fee. Then drop that number into the mortgage calculator and watch what it does to your payment as a buydown.
