The 3-2-1 Buydown: Buying Down Your Rate Without Marrying It

When rates climbed off their historic lows, buyers froze and sellers blinked first. The 3-2-1 buydown became the deal-saving tool of choice: a way to start your payment as if rates were 3% lower, step up gradually, and let someone else — usually the seller — foot the bill. It's often misunderstood as a gimmick. It's actually a straightforward escrow arrangement, and in the right deal it's the best concession you can negotiate.

Say your note rate is 7%. With a 3-2-1 buydown, your payments in year one are calculated at 4%, year two at 5%, year three at 6%, and from year four onward at the actual 7%. The difference between each year's reduced payment and the real payment isn't waived — it's prepaid. At closing, a lump sum covering the entire three-year subsidy goes into an escrow account, and each month the servicer draws the gap from that account. Your loan was always a 7% loan; the buydown just schedules who pays which part of it, and when.

• Sellers and builders fund most buydowns as a closing concession — it's a price cut that shows up in your monthly payment instead of the sticker.
• The same dollars go further: a $15,000 price reduction might trim your payment by $90 a month, while $15,000 in buydown escrow can cut year-one payments by several hundred.
• Builders love them because the list price — and the comp it sets for the next sale — stays intact.
• Buyers can self-fund, but that's rarely optimal; if it's your own cash, permanent points usually serve you better.

Permanent discount points lower your rate for the life of the loan; a temporary buydown lowers your payments for two or three years. The break-even logic is different. Points pay off if you keep the loan for many years. A buydown pays off if the early years are the tight ones — you're growing a business, expecting income to rise, or betting rates will fall enough to refinance before the subsidy runs out. And here's the underrated feature: if you refinance or sell mid-buydown, the unused escrow balance is credited back. You're not forfeiting it.

• You qualify at the note rate, not the bought-down rate — the buydown doesn't stretch your approval, by design. That's your protection against payment shock.
• Year four is the real payment. Budget for it from day one; the step-up schedule is printed on your buydown agreement.
• Concession caps apply — seller contributions have limits that vary by loan type and down payment, and the buydown counts against them.
• 2-1 and 1-0 versions exist — same mechanics, smaller subsidy, cheaper to fund. The right size depends on how much concession you can negotiate.

The buydown question is really a negotiation question: how much can you get the seller to contribute, and where do those dollars work hardest? That's a math problem with a clean answer. Bring me the price, the concession on the table, and your timeline, and I'll show you the same dollars three ways — price cut, permanent points, and a 3-2-1 — so you can see exactly which one wins for your situation.
