How the discount actually works
A 2-1 buydown is not a different loan, it is a temporary discount stacked on top of a standard one. Your rate runs 2 percent below your permanent rate in year one, 1 percent below in year two, then settles at your actual rate for the rest of the loan. The money that covers that discount sits in an account funded at closing, most often by the seller or the builder.
You still qualify for the loan at your full permanent rate, not the reduced year-one payment. The buydown changes what you pay, not what you need to qualify for.
The best version of this costs you nothing
In a market where sellers are motivated to close, asking for a 2-1 buydown instead of a straight price reduction is often worth more to you in real dollars, even though it can feel like the smaller ask in a negotiation. This calculator shows you exactly what that request is worth, which is the number to bring into that conversation.
Builders in particular often have buydown programs already built into their incentives on new construction, especially in the newer developments around Kyle, Buda, and Dripping Springs. It is always worth asking what they are willing to fund before assuming the sticker price is the only number in play.
What happens if you refinance before year three
If rates drop and you refinance before the buydown period ends, what happens to the unused funds depends on how the buydown account was structured. Some structures return the remaining balance to you at payoff, others do not. That detail matters enough that I confirm it in writing before you count on that money twice.
It is a real consideration, not a reason to avoid a buydown. Just one more thing worth understanding upfront rather than assuming.
A buydown is not the same as buying points
Paying points buys your rate down permanently for the life of the loan. A 2-1 buydown lowers it temporarily for two years, then you are at your permanent rate either way. Which one makes more sense depends on how long you plan to hold the loan and who is actually paying for it, you or the seller.
If you are the one funding it out of pocket, a permanent rate buydown often makes more sense than a temporary one. If someone else is funding it as part of the deal, the calculation flips, since a temporary discount you are not paying for is close to free money either way.
