What do new construction rate buydowns actually cost buyers in Prosper and Celina?
Builders in Prosper and Celina are advertising $10,000 to $30,000 in incentives through 2/1 rate buydowns, temporarily dropping your first-year rate to around 2.875% to 3%. Most of these offers require you to use the builder’s preferred lender, which can mean a higher base price that offsets some or all of the savings. Running the full numbers, not just the advertised rate, is the only way to know if the incentive is actually worth it for your situation.

That banner in the builder’s model home advertising a rate in the 2s is real. It’s also not the whole story. Here’s what’s actually being offered right now in Prosper and Celina, and what to check before you assume it’s the deal it looks like.
What builders are actually offering right now
New construction incentives across Prosper and Celina are aggressive at the moment, and they’re worth understanding before you walk into a sales office:
- M/I Homes, building Lilyana in the Prosper/Celina corridor, has been posting 2/1 buydowns that bring first-year FHA rates down near 2.875%.
- KB Home in Celina has offered builder credits north of $20,000 on select inventory.
- Serenade, a Celina community with multiple builders including CastleRock, DRB, HistoryMaker, Impression, Risewell, and UnionMain, has seen a mix of flex cash and buydown offers across its lineup.
Across the market, the typical structure is $10,000 to $30,000 in incentive money, applied either as a 2/1 temporary rate buydown or as flex cash you can direct toward closing costs, upgrades, or a permanent rate buydown. On a $350,000 home, a 2/1 buydown typically saves $300 to $500 a month in year one.
That’s a meaningful number. It’s also not free money.
The catch most buyers miss
A 2/1 buydown means your rate is reduced by 2 percentage points in year one, 1 point in year two, and then steps up to the full note rate in year three. You need to qualify, and budget, as if you’re paying the full rate from day one. The first two years are a cushion, not a permanent discount.
The bigger catch is the lender requirement. Most builders tie their buydown or credit offer to their in-house or preferred lender. That’s usually where the real cost hides. If the builder’s base price is a few thousand dollars higher than what you’d negotiate using an outside lender, some or all of your “savings” just got baked back into the purchase price.
This is exactly why I tell buyers not to compare the incentive in isolation. Compare the total out-the-door cost, list price, incentive, and financing terms together, against what the same builder would offer with an outside lender and no incentive attached.
How to actually run the math before you sign
A few steps before you commit to any builder incentive:
- Get pre-approved with an outside lender first. This gives you a real number to compare against, instead of taking the builder’s offer at face value.
- Ask the sales office directly what the price would be without the preferred-lender requirement. Reputable builders will tell you. If they won’t, that’s information too.
- Calculate the total cost over your expected time in the home, not just the year-one payment. A 2/1 buydown looks great in year one and less great once it steps up.
- Factor in any MUD or PID assessments. Many new construction communities in Prosper and Celina carry these on top of your mortgage payment, and they don’t show up in the rate-buydown math at all.
If you want the fuller picture on how new construction pricing compares to resale in this market, I walked through that math in New Construction or Resale in Prosper and Celina Right Now?, and the MUD/PID piece specifically is covered in MUD and PID Fees in Prosper and Celina: What New Construction Buyers Actually Pay.
What this means for your next step
None of this means builder incentives are a bad deal. Many of them are genuinely good, especially in a market where builders are competing hard for buyers. It means the advertised rate isn’t the number that matters. The total cost is.
This is exactly the kind of comparison I run for every client looking at new construction in Prosper or Celina, because the builder’s sales office is never going to walk you through the outside-lender comparison for you. That’s not their job. It’s mine.
Frequently Asked Questions
What is a 2/1 rate buydown, and how does it work?
A 2/1 buydown temporarily lowers your mortgage rate by 2 percentage points in year one and 1 point in year two, then returns to the full note rate in year three. It’s usually funded by the builder or seller as an incentive, and you need to qualify and budget as though you’re paying the full rate from the start.
Do I have to use the builder’s lender to get the incentive?
In most cases, yes. Builder incentives in Prosper and Celina are typically tied to their in-house or preferred lender, and using an outside lender usually means forfeiting the buydown or credit. That’s the tradeoff to run the numbers on before deciding.
Is a rate buydown better than asking for a lower price?
It depends on your timeline and how the builder’s base price compares to an outside-lender scenario. If you plan to stay in the home long-term, a permanent rate reduction or price cut may save you more over time than a temporary 2/1 buydown. This is worth running as a side-by-side comparison, not a gut call.
How much can a rate buydown actually save me?
On a typical $350,000 home in this market, a 2/1 buydown saves roughly $300 to $500 a month in year one, tapering in year two before returning to the full payment in year three. The total savings depend on the specific loan amount, rate, and incentive structure offered.
Are these incentives available on resale homes too, or just new construction?
Rate buydowns can technically be used on resale homes if a seller agrees to fund one, but they’re far more common on new construction because builders have more margin to work with and a strong incentive to move inventory. On resale, this is something your agent can negotiate for you as part of the offer.
Every builder deal is a little different, and the only way to know if the incentive actually pencils out is to run your specific numbers before you sign anything.
