Ask the Expert: Is a 2-1 Buydown Really a Good Deal?

A builder is offering us a “2-1 buydown” on the new house we’re considering. The first year’s interest rate sounds great, but I’m not sure I understand the catch. What is a buydown, and is it worth it?

You are right to ask. A mortgage buydown can be a real financial advantage — or simply attractive marketing — depending on how long you plan to stay in the home and who is paying for it.

A buydown simply means someone pays money up front so your interest rate starts lower than the market rate.

There are two main types, and they work very differently.

Temporary buydowns

The “2-1 buydown” your builder mentioned is temporary.

Here is how it works:
• Year 1: your interest rate is reduced by 2%
• Year 2: reduced by 1%
• Year 3 onward: you pay the full loan rate

For example, on a $400,000 mortgage with a 6.25% note rate:
• Year one payments may be roughly $500 lower per month
• Year two may save around $260 monthly
• After that, the payment resets to the full amount

That can provide meaningful breathing room during the first couple of years of homeownership, especially while buyers are furnishing the home, adjusting budgets, or waiting for income to rise.

But there is an important catch:

You still must qualify for the mortgage using the full payment amount — not the discounted starter payment.

Lenders want to know you can afford the loan after the temporary discount disappears.

Permanent buydowns

A permanent buydown works differently.

Instead of temporarily reducing the rate, buyers pay “discount points” upfront to permanently lower the interest rate for the life of the loan.

Typically:
• One point equals 1% of the loan amount
• One point usually lowers the rate by about 0.25%

On a $400,000 loan, one point would cost about $4,000 upfront.

The savings continue every year for the entire mortgage term.

Most buyers reach the “break-even point” after roughly five to six years. That means if you stay in the home longer than that, the permanent buydown often saves more money overall.

If you expect to move or refinance sooner, the temporary buydown may make more sense.

Why builders like offering buydowns

In today’s market, many builders and sellers are offering concessions to attract buyers without officially cutting home prices.

A buydown often costs the seller less than reducing the purchase price by an equivalent amount, while making the monthly payment look significantly more affordable to buyers.

That is why buydowns have become increasingly common in 2026.

The key question to ask

The real issue is not whether the temporary payment looks attractive.

The important question is:
Can you comfortably afford the full payment once the buydown ends?

Ask your lender to compare:
• the temporary buydown
• the permanent buydown
• and the standard loan

Side-by-side numbers usually make the decision much clearer.

A good lender will gladly walk through the math with you.
