Temporary Rate Buydowns in Colorado: 3-2-1, 2-1 and 1-1 Explained

A seller-paid buydown lowers your payment for the first years of the loan. Here is the escrow arithmetic behind all three structures, and the concession cap that usually picks which one you get.

Temporary Rate Buydowns in Colorado: 3-2-1, 2-1 and 1-1 Explained
The short version

A temporary rate buydown lowers your interest rate for the first years of the loan, paid for out of an escrow account the seller funds at closing. A 2-1 drops your rate 2% in year one and 1% in year two, then you are at the note rate for the rest of the term.

On a $550,000 home with 5% down, a 2-1 costs the seller about $12,108 and takes your first-year principal and interest from $3,432 to $2,765. You still qualify at the full rate, and if you refinance or sell early the unused escrow goes to your loan rather than to the lender.

We price buydowns by hand against a price cut and show you both, on your actual file.

Every temporary buydown works the same way underneath. You take a normal 30-year fixed at whatever the market gives you, and then a pot of money sits in escrow and pays part of your payment for the first year or two or three. The rate on your note never changes. What changes is who writes the check each month.

Almost always the seller funds it, as a concession negotiated into the contract. That matters because it puts the buydown in direct competition with a price reduction, which is a comparison we run below rather than hand-waving at.

Same house, three structures
$550,000 home, $522,500 loan at 6.875%
Structure Year 1 payment Year 1 saving Seller funds Fits the cap at 95% LTV?
1-1 $3,091 $342/mo $8,200 1.5% of price — fits conventional 3%
2-1 $2,765 $667/mo $12,108 2.2% of price — fits conventional 3%
3-2-1 $2,457 $975/mo $23,814 4.3% of price — needs FHA 6% or more down

Principal and interest at 6.875%, 30-year fixed, $3,432 at the note rate. At 5% down the conventional cap is 3% of the price. Put 10% down and it doubles to 6%. That last column is why the cap picks the structure as often as preference does.

The examples in the videos

The three videos above are walked through on a $500,000 purchase at 6.25%, a $3,603 monthly payment before any buydown. Those are Matt's numbers off real files, and they are the figures you will hear on camera.

From the videos
$500,000 at 6.25%, payment $3,603
Structure Effective rate Seller funds What the buyer sees
1-1 5.25% in years 1 and 2 $7,785 A full point off for two full years, the cheapest structure to get agreed to.
2-1 4.25%, then 5.25% $11,479 Payment drops to $2,971 in year one, with the escrow adding $632 a month, then $324 a month in year two.
3-2-1 3.25%, 4.25%, 5.25% about $17,000 Three years of relief, the largest concession and the hardest to fit inside a cap.

Figures from Speak Straight Mortgage's own files at the rates in effect when the videos were recorded. The tables further down run the same structures at a different price and today's illustrative rate, which is why the dollar amounts differ. As a share of purchase price the two agree closely: a 1-1 lands near 1.5% either way.

The 2-1 buydown

How a seller-paid 2-1 buydown works, start to finish. Walked through by Matt Wentz on a real file.
The escrow account, year by year
A 2-1 buydown on a $550,000 home
$27,500 down, a $522,500 loan at 6.875%. Principal and interest at the note rate is $3,432 a month, and that is the payment you qualify on.
Period Effective rate What you pay Escrow covers Cost that year
Year 1 4.875% $2,765 $667 $8,008
Year 2 5.875% $3,091 $342 $4,100
Total the seller funds at closing $12,108

Principal and interest only, illustrative at 6.875% on a 30-year fixed. Taxes, insurance and any HOA sit on top of every figure here and do not change. Your rate is set the day you lock.

The 3-2-1 buydown

The three-year version, and when the concession cap kills it. Walked through by Matt Wentz on a real file.

The 1-1 buydown

The cheapest structure, and the one sellers agree to most readily. Walked through by Matt Wentz on a real file.
The escrow account, year by year
A 1-1 buydown on a $550,000 home

The four rules that decide whether this works

You qualify at the note rate, not the bought-down rate. On a temporary buydown the lender underwrites the payment at the full rate. The lower payment is real money in your pocket, but it does not stretch your approval by a dollar, and anyone telling you otherwise is describing a different product.

The money sits in an escrow account, and it is yours. The seller funds it at closing and the servicer draws from it each month to make up the difference. If you refinance or sell before the buydown runs out, the unused balance is applied to your loan, so it is not forfeited.

Concessions are capped, and the cap is what limits the buydown. On a conventional primary residence the seller can contribute 3% if you are putting less than 10% down, 6% once you are at 10% down or more, and 9% at 25% down or more (those are the 90%, 75.01-to-90%, and 75%-or-below loan-to-value tiers). FHA allows 6%. VA is the one that gets quoted wrong. You will hear a flat 4%, but only some seller-paid items count toward it and others do not, so the total a seller can contribute on a VA loan is often higher than 4%. It is worth having someone work it out on your file rather than assuming the 4% is the ceiling. USDA allows 6%. A 3-2-1 on a low down payment often will not fit inside the cap, which is the single most common reason one gets restructured.

It is a negotiation, not a product you order. The seller is paying for it, so it competes with a price reduction and with closing-cost help. Which of the three is worth more to you depends on how long you keep the loan, and that is arithmetic we will run rather than guess.

When we tell people not to do it

If you are stretching to qualify and counting on refinancing before the buydown expires, the answer is no. The payment goes up on a fixed schedule whether rates cooperate or not, and year three arrives regardless. A buydown should make a payment you can already carry more comfortable, not make an impossible payment look possible for twenty-four months.

The other case is a seller who will trade either way. If they are indifferent between funding a buydown and cutting the price, the longer you plan to keep the loan the more the price cut wins, because it lowers what you owe forever instead of for two years.

Frequently Asked Questions

What is a temporary rate buydown?
A temporary rate buydown lowers your interest rate for the first years of a 30-year fixed loan using money held in an escrow account, usually funded by the seller at closing. A 2-1 buydown cuts the rate 2% in year one and 1% in year two, then the payment settles at the note rate for the remaining 28 years.
How much does a 2-1 buydown cost?
The cost is the sum of the payments the escrow covers. On a $550,000 Colorado home with 5% down at 6.875%, a 2-1 buydown costs about $12,108 and lowers first-year principal and interest from $3,432 to $2,765.
Do I qualify at the lower buydown payment?
No. Lenders underwrite a temporary buydown at the note rate, so the reduced payment does not increase how much you can borrow. It lowers what you actually pay in the early years, which is a cash-flow benefit rather than a qualifying one.
What happens to the buydown money if I refinance early?
The unused balance in the escrow account is applied to your loan rather than kept by the lender, so refinancing or selling before the buydown expires does not forfeit the remaining funds.
Can the seller pay for the buydown?
Yes, and that is the normal arrangement. The limit is the seller-contribution cap for your loan type: 3% under 10% down, 6% at 10% down or more, and 9% at 25% down or more on a conventional primary residence, 6% on FHA and USDA, and something more nuanced on VA than the 4% commonly quoted where a temporary buydown counts as a concession.
Is a buydown better than a lower purchase price?
It depends on how long you keep the loan. A buydown delivers a large benefit in the first two years, while a price reduction lowers your balance and payment for the entire term. If you expect to stay past about five years, the price cut is usually worth more.
