What Is a Mortgage Rate Buydown and How Does the 2-1 Buydown Work?

What Is a Mortgage Rate Buydown?

A mortgage rate buydown is an arrangement where an upfront cash payment — typically from the seller, builder, or lender — temporarily or permanently reduces the buyer's interest rate. Buydowns became popular in high-rate environments as a way for sellers to make their listings more attractive and help buyers with initial affordability.

The 2-1 Buydown: How It Works

In a 2-1 buydown, the buyer's effective interest rate is reduced by 2 percent in year 1, 1 percent in year 2, and then returns to the full note rate from year 3 onward for the life of the loan. On a loan with a 7.0 percent note rate: Year 1 rate is 5.0 percent, Year 2 rate is 6.0 percent, Year 3 and beyond rate is 7.0 percent.

Who Pays for the Buydown?

• Seller contribution: Sellers offer buydown funds as a concession — often instead of or in addition to a price reduction
• Builder contribution: New construction builders frequently offer buydowns as incentives
• Lender credit: Some lenders offer temporary buydowns as part of their loan products
• Buyer-paid: Buyers can fund their own buydown, though this is less common

Is a 2-1 Buydown a Good Deal?

The math depends on how long you stay in the home and whether you refinance. If you plan to refinance when rates fall, the buydown funds effectively reduce your payments for the period before refinancing — which can be valuable. If you keep the loan at the full rate for 30 years, the buydown may have cost more than it saved. Run the numbers with your lender for your specific scenario.

Negotiating Buydowns in San Diego

In markets where sellers are motivated, asking for a buydown as part of your offer can be more effective than a purchase price reduction — because it directly reduces your monthly payment in the critical first years of ownership.
