Short answer: a builder’s advertised rate buydown on a new construction home in Las Vegas can be easier to access than negotiating a buydown on a resale, because the builder may already have a financing incentive in place. But it often requires using the builder’s preferred or affiliated lender, may apply only to certain homes or closing dates, and the headline rate doesn’t necessarily tell you the full cost of the deal. A resale rate buydown has to be negotiated with the seller, but you generally have more freedom to shop your mortgage with the lender of your choice.
I get asked to compare these two paths almost every week right now. Usually it’s a buyer who is looking at new construction while also considering a resale home they like just as much, trying to figure out which option actually gives them more value for the money. Here is how the two compare.
How does a builder’s rate buydown actually work?
A builder’s rate incentive is typically part of the builder’s overall sales promotion and may be offered through its in-house, preferred, or affiliated mortgage company. In many cases, you have to use that lender to receive the advertised financing incentive, and the offer may be limited to certain homes, loan programs, or closing dates.
The incentive can take different forms. It might be a temporary buydown that lowers the effective payment for the first year or two, or a permanent rate reduction that applies for the life of the loan.
As of August 27, 2026, Freddie Mac’s Primary Mortgage Market Survey put the average 30-year fixed mortgage rate at 6.66%. At the same time, Las Vegas-area builders were advertising promotional financing well below that rate on qualifying new construction homes. For example, Pulte was advertising a first-year rate as low as 1.99% on select homes, with specific terms and eligibility requirements. That 1.99% figure is an introductory rate, not necessarily the permanent note rate.
How does negotiating a buydown on a resale home differ?
On a resale purchase, there is no standard builder incentive program. You or your agent can ask the seller to contribute toward a temporary or permanent rate buydown as part of the offer, similar to asking for a closing-cost credit or other seller concession.
The advantage is flexibility: you can generally choose your own lender and compare mortgage options independently. The tradeoff is that the seller has to agree to the concession, and their willingness will depend on the home’s price, market conditions, competing offers, time on market, and their own financial situation.
New construction buydown vs. resale negotiated buydown
| Factor | New Construction Buydown | Resale Negotiated Buydown |
|---|---|---|
| Who typically funds it | Builder, through its sales incentive budget | Seller, only if you ask for it in the offer |
| Lender flexibility | Often tied to the builder’s captive lender | Full freedom to shop any lender |
| How predictable it is | Advertised up front, changes monthly by community | Case by case, depends on seller motivation |
| Best leverage point | End of a sales phase or on aged inventory homes | Homes that have sat on market longer than average |
| Main risk | Incentive may be baked into the price; captive lender rate may not be the most competitive | Seller may prefer a price reduction instead, or have no room at all |
Which one actually saves you more money?
It depends on the entire deal—not just the advertised interest rate.
A builder’s incentive can be valuable, but you should compare the builder’s price and financing package against what the same home would cost with outside financing. A lower promotional rate doesn’t automatically mean you’re getting the better deal if the loan has different fees, terms, or restrictions.
With a resale, a negotiated buydown gives you another way to reduce the cost of financing without relying on a builder’s incentive program. But you’re depending on the seller’s willingness to contribute.
The only reliable way to know which option puts you ahead is to run the actual numbers: purchase price, incentives, loan amount, interest rate, closing costs, monthly payment, and comparable resale values.
What should you check before taking a builder’s buydown offer?
- Get a quote from an independent lender and compare it line by line against the builder’s captive lender quote, not just the headline rate.
- Ask your agent to pull recent closed comps for that specific community to check whether the base price already reflects the cost of the incentive.
- If it’s a temporary buydown, run your budget assuming the payment resets to the full note rate in year two or three, not just the introductory payment.
- Confirm in writing exactly what the incentive covers and whether it changes if you switch lenders.
- Weigh how long you plan to keep the loan. A temporary buydown or a resale price reduction can outperform a permanent buydown if you don’t plan to stay long term.
