Calculate Your Mortgage Buydown Savings

What is a Temporary Interest Rate Buydown?

A temporary interest rate buydown is a mortgage financing option that reduces your interest rate for the first few years of your loan. The most common types are:

• 2/1 Buydown: Rate drops 2% in year one and 1% in year two before returning to the original note rate.

• 3/1 Buydown: Rate drops 3% in year one, 2% in year two, and 1% in year three before returning to the note rate.

These staged reductions lower monthly payments early, giving borrowers breathing room while adjusting to mortgage costs.

How It Can Lower Your Monthly Payments

For example, on a $300,000 mortgage at 6% over 30 years:

• 2/1 Buydown:

  • Year 1: 4% → $1,432/month

  • Year 2: 5% → $1,610/month

  • Year 3+: 6% → $1,799/month

• 3/1 Buydown:

  • Year 1: 3% → $1,264/month

  • Year 2: 4% → $1,432/month

  • Year 3: 5% → $1,610/month

  • Year 4+: 6% → $1,799/month

Savings can add up to thousands of dollars in the first few years, freeing cash for renovations, moving costs, or savings.

Who Benefits Most

Temporary buydowns are ideal for:

• First-time homebuyers easing into mortgage payments

• Buyers expecting income growth in the next few years

• Investors wanting higher early cash flow

• Buyers with seller or builder incentives

Short-term buyers or those with static income may want to carefully evaluate rising payments after the buydown period.

Using the Buydown Calculator

Our calculator models both 2/1 and 3/1 buydowns. Enter your loan amount, interest rate, and term to see how much you could save. It also highlights your break-even point — when the upfront buydown cost is recouped.

Costs and Considerations

• Upfront fees: Paid by you, seller, or builder

• Payment increase: Prepare for higher payments after the buydown ends

• Homeownership timeline: Short-term stays may reduce total savings

• Loan structure impacts: Could affect overall cost

Think of a temporary buydown as early financial relief, not a permanent rate reduction.

Is a 2/1 or 3/1 Buydown Right for You?

If you want temporary relief, anticipate income growth, or have seller incentives, either buydown can make homeownership more affordable.

If you prefer stable, long-term payments, a fixed-rate mortgage may be the better choice.

Frequently Asked Questions About Mortgage Buydowns

What is a temporary mortgage buydown?

A temporary mortgage buydown is a financing option where the interest rate is reduced for the first few years of the loan. The most common types are a 2/1 buydown (rate drops 2% in year one and 1% in year two) and a 3/1 buydown (rate drops 3% in year one, 2% in year two, and 1% in year three). After the buydown period, the rate returns to the permanent note rate.

How does a 2/1 buydown work?

With a 2/1 buydown, your interest rate is reduced by 2% in the first year and 1% in the second year. For example, if your note rate is 6%, you would pay 4% in year one, 5% in year two, and 6% from year three onward. This lowers your monthly payment during the early years of the loan.

How does a 3/1 buydown work?

A 3/1 buydown reduces your interest rate by 3% in year one, 2% in year two, and 1% in year three. If your note rate is 6%, you would pay 3% in year one, 4% in year two, 5% in year three, and 6% from year four onward. This provides even greater early payment relief than a 2/1 buydown.

Who pays for a mortgage buydown?

The buydown cost can be paid by the buyer, the seller, the builder, or the lender. In many purchase transactions, the seller or builder agrees to fund the buydown as an incentive to close the deal. The upfront cost is typically equal to the total savings the borrower receives during the reduced-rate period.

Is a temporary buydown worth it?

A temporary buydown can be worth it if you expect your income to rise, want lower payments initially, or receive seller concessions to cover the cost. It is less beneficial if you plan to sell or refinance before the break-even point, or if you cannot afford the higher payments after the buydown period ends.

Can I use a buydown on a USDA loan?

Yes, temporary buydowns are permitted on USDA loans. Sellers, builders, or lenders can contribute funds to buy down the interest rate. Be sure to check current USDA guidelines and lender requirements, as program rules may vary. For more details, see our guide to USDA loan seller concessions.
