A 2-1 buydown or a permanent rate buydown? How to tell which one fits

Short answer: a 2-1 buydown gives the client a big payment break for the first two years and then the rate snaps back, so it fits a client who expects to refinance soon or needs early breathing room. A permanent buydown costs more upfront and lowers the rate for the whole loan, so it fits a client who plans to keep the loan for years. Same goal, lower payment, two very different bets. Here is how to tell them apart for a client.

What is the difference between the two?

A permanent buydown is prepaid interest. The client pays points at closing and the rate is lower for the life of the loan. It never changes back.

A 2-1 buydown is a temporary subsidy, usually paid by the seller or the builder. The rate is two points lower in year one, one point lower in year two, then it returns to the full note rate in year three and stays there. The note rate never actually changed. The client just got help with the first two years of payments.

That difference, permanent versus temporary, is the whole decision.

How do the payments compare?

Take a $400,000 loan at a 6.75 percent note rate. Here is what each option looks like.

Option	Year 1 payment	Year 2 payment	Year 3 onward	Who usually pays
No buydown	about $2,595	about $2,595	about $2,595	Nobody
2-1 buydown	about $2,130 (at 4.75%)	about $2,355 (at 5.75%)	about $2,595 (at 6.75%)	Seller or builder
Permanent buydown (1 point)	about $2,530 (at 6.5%)	about $2,530	about $2,530	Client, at closing

The 2-1 gives the biggest early relief and costs the client nothing if the seller funds it. The permanent buydown costs real money upfront and gives a smaller break, but it never goes away.

When does each one win?

The 2-1 buydown fits three situations. The client expects rates to fall and plans to refinance inside two or three years, so the temporary rate is a bridge. The client is stretching a little at the start, maybe new to a payment this size, and wants room to settle in. Or there is a motivated seller who would rather fund a buydown than cut the price.

The permanent buydown fits the opposite client. They plan to keep this loan for the long haul, they have the cash at closing, and they would rather lock a lower payment forever than get a short break that disappears. If they keep the loan past the breakeven on the points, the permanent buydown pays them back every month after that. The breakeven math is the same as any discount-point decision.

The trap to name out loud

The 2-1 buydown has a quiet risk: the client has to qualify at the full note rate, not the bought-down rate. So they need to be comfortable with the year-three payment from day one. If they are counting on a refinance that may not happen, the payment that returns in year three can sting.

Say it plainly: “This lowers your payment for two years, then it goes back up to this number. Let me make sure you are comfortable with that number before we lean on the early break.” That one sentence keeps a happy client from becoming an angry one in year three.

This is the heart of winning the rate conversation: you are not selling a gimmick, you are matching the structure to how the client actually plans to use the loan. In WealthLens you can build the bought-down version and the plain version side by side and show the client every year of payments, so the bet they are making is on the screen instead of in their head.
