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.

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.
