A 2-1 buydown is a mortgage agreement that provides for a low interest rate for the first year of the loan, a somewhat higher rate for the second year, and then the full rate for the third and later years.

How 2-1 Buydowns Work

A buydown is a real estate financing technique that makes it easier for a borrower to qualify for a mortgage with a lower interest rate. That lower rate can last for the duration of the mortgage (as is often the case when borrowers pay extra points up front to the lender) or for a particular period of time. A 2-1 buydown is one kind of temporary buydown, in this case lasting for two years.

In a 2-1 buydown, the interest rate will increase from one year to the next until it settles into its permanent rate in year three. To make up for the interest that they won’t be receiving in those early years, lenders will charge an additional fee.

Either a homebuyer or a home seller can pay for a buydown. That payment may be in the form of mortgage points or a lump sum deposited in an escrow account with the lender and used to subsidize the borrower’s reduced monthly payments.

Sellers, including home builders, often use 2-1 buydowns as an incentive for potential purchasers.

Example of a 2-1 Buydown Mortgage

Suppose a real estate developer is offering a 2-1 buydown on its new homes. If the prevailing interest rate on 30-year mortgages is 5%, a homebuyer could get a mortgage that charged just 3% in the first year, then 4% in the second year, and 5% after that. If the homebuyer took out a $200,000, 30-year mortgage, for example, then their monthly payments during the first year would be $843. In the second year, they would pay $995. After the end of the second year, their monthly payment would rise to $1,074, where it would stay for the remainder of the mortgage.

2-1 Buydown Pros and Cons

For home sellers, a 2-1 buydown can help them by making it easier and sometimes faster for them to sell their homes for a good price. The downside, of course, is that it comes at a cost, which ultimately reduces how much they will net from the sale. For homebuyers, a 2-1 buydown has several potential benefits. For one thing, it can help them afford a larger mortgage and a more expensive home than they might otherwise qualify for. For another, it buys them some time before their mortgage payments rise to the full amount, which can be helpful if their income is also rising from year to year. The downside for homebuyers is the risk that their income won’t keep pace with those increasing mortgage payments. In that case, they might find themselves stretched too thin and even have to sell the home.

When to Use a 2-1 Buydown

Home sellers may want to consider offering (and paying for) a 2-1 buydown if they’re having difficulty selling and need to provide an incentive to find a buyer. Borrowers may benefit from a buydown if it allows them to buy the home they want at a price they can afford. However, they will also want to consider what would happen if their income doesn’t rise fast enough to keep up with their future monthly payments. Buyers should also make sure that they are getting a fair deal on the home in the first place. That’s because some sellers might increase the home’s price to make up for the cost of the 2-1 buydown.

Note that buydowns may not be available under some state and federal mortgage programs or from all lenders. A 2-1 buydown is available on fixed-rate Federal Housing Administration (FHA) loans, but only for new mortgages and not for refinancing. Terms can also vary from lender to lender.
