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.

Use the calculator above to compare scenarios and plan your mortgage with confidence.

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 2-1 Rate Buydowns

What is a 2-1 rate buydown?

A 2-1 rate buydown is a mortgage financing strategy where the interest rate is reduced by 2% in the first year and 1% in the second year, before returning to the original note rate in year three. This lowers your monthly payments during the early years of homeownership. Our 2-1 rate buydown calculator above lets you model these exact savings.

How much does a 2-1 buydown cost?

The cost of a 2-1 buydown is equal to the total savings you receive over the two reduced-rate years. On a $300,000 mortgage at 6%, that cost is typically around $4,500 to $5,500, paid upfront by the buyer, seller, or lender. Use the calculator to estimate your specific buydown cost.

Who pays for a mortgage buydown?

A mortgage buydown can be paid by the buyer, the seller, the builder, or the lender. In many purchase transactions, the seller or builder offers a buydown concession as an incentive to close the deal. Seller concessions on a conventional loan often cover this cost.

Is a 2-1 buydown worth it?

A 2-1 buydown is worth it if you need lower payments in the first two years, expect your income to grow, or receive seller concessions. It is less beneficial if you plan to sell or refinance within the first few years. Compare your options with our rate/term refinance calculator if you are considering a future refinance.

What happens after the buydown period ends?

After the buydown period, your monthly payment increases to the permanent note rate. For a 2-1 buydown, this happens in year three. For a 3-1 buydown, it happens in year four. Budget for this increase in advance. If you are concerned about the higher payment, explore our conventional loan credit score requirements to see if you qualify for a lower permanent rate.
