A 2-1 buydown can be a useful option for buyers who want lower mortgage payments in the first years of homeownership—especially in today’s higher-rate market. Whether you’re buying a house in Austin, TX or searching for a home in Denver, CO, this temporary rate-reduction option can make the early years of a mortgage more affordable.
This Redfin article breaks how a 2-1 buydown works, who qualifies, what it costs,, pros and cons, and how it compares to alternatives like permanent buydowns, ARMs, and seller concessions.
What is a 2-1 buydown?
A 2-1 buydown is a temporary mortgage arrangement where your interest rate is reduced for the first two years of your loan:
- Year 1: Rate is 2 percentage points lower
- Year 2: Rate is 1 percentage point lower
- Year 3+: Rate returns to the full note rate for the remainder of the loan
The seller, builder, lender, or buyer pays an upfront fee to “buy down” the interest rate for those first two years, creating lower monthly mortgage payments at the beginning of the loan.
Key takeaway: A 2-1 buydown does not permanently reduce your interest rate. Most buyers use it to ease into monthly payments or bridge the gap until refinancing becomes an option, but future rate drops are not guaranteed.
How a 2-1 buydown works (with example)
Let’s say you’re buying a home with:
- Loan amount: $400,000
- Note rate: 6.5%
- Loan type: 30-year fixed
With a 2-1 buydown, your rate would look like:
- Year 1: 4.5%
- Year 2: 5.5%
- Year 3–30: 6.5%
Payment comparison
| Year | Rate | Monthly principal & interest |
| 1 | 4.5% | ~$2,027 |
| 2 | 5.5% | ~$2,271 |
| 3–30 | 6.5% | ~$2,528 |
Note: These figures reflect principal and interest only. Your full payment (including taxes, insurance, and HOA if applicable) will be higher.
Savings:
- Year 1: Save ~$501/month
- Year 2: Save ~$257/month
- Total temporary savings: ~$9,096
