The 2/1 Buy Down
Mortgage Explained
A seller-funded strategy that temporarily lowers your interest rate for the first two years โ giving buyers immediate payment relief.
What is a 2/1 Buy Down?
A 2/1 Buy Down is a financing arrangement โ typically paid by the seller or builder โ where the borrower's interest rate is reduced by 2% in year one and 1% in year two, then settles at the permanent note rate starting year three. The full market rate applies for the life of the loan, but the early savings help buyers adjust to homeownership costs.
Seller Funds Escrow
The seller deposits a lump sum into a buydown escrow account at closing.
Year 1 Rate Drops
Borrower pays 2% below the note rate. Escrow covers the difference.
Year 2 Rate Drops
Borrower pays 1% below note rate. Escrow continues to subsidize.
Year 3 Onward
Borrower pays the full permanent note rate for the remainder of the loan.

๐ผ Who Typically Pays?
- Seller (most common in buyer's markets)
- Home builder or developer as incentive
- Buyer can fund it themselves
- Lender credit (less common)
- Unused funds returned to buyer if they sell or refi early
โ Why Buyers Love It
- Lower payments while getting settled
- Easier to qualify at reduced rate
- Expect income growth to cover year 3 payment
- Bet on refinancing before full rate kicks in
- Negotiate seller concession instead of price cut
Important: The borrower qualifies at the full note rate (e.g., 4.99%), not the buydown rate. The buydown only affects monthly cash flow โ not loan approval. If the borrower sells or refinances, any unused escrow funds are typically returned. Always consult a licensed mortgage professional for your specific scenario.
