New Build vs Resale Las Vegas: Why $600K Beats $500K

A $600,000 new construction home in Las Vegas can carry a lower monthly payment than a $500,000 resale home right now. The reason is builder rate buydowns: several national builders are running in-house lender promotions with first-year rates as low as 1.99 percent, while resale sellers are not buying anyone's rate down. Here is the full year-by-year math, including what the buydown does not cover.

If you're in California watching Las Vegas listings, you've probably been sorting by price. Lower sticker, lower payment. That's how it has always worked.

Right now, it doesn't.

As of today, the 30-year conventional mortgage rate is averaging about 6.6 to 6.7 percent (Bankrate, Freddie Mac, August 2026). At the same time, several builders in this valley are offering first-year rates as low as 1.99 percent through their own in-house lenders, stepping up to a permanent rate by year three. That's a gap of roughly 270 to 290 basis points in year one, one of the widest spreads I've seen.

When the gap gets that wide, something strange happens. The more expensive house becomes the cheaper monthly payment.

Here is the math, line by line.

What Are We Actually Comparing?

I'm comparing two real scenarios I see every week in this valley: a $600,000 new build with a builder buydown, and a $500,000 resale with a standard market-rate loan.

The new build. Six hundred thousand dollars. One national builder is running a summer promotion with an incentive stack worth up to eighty-five thousand dollars, plus a buydown that puts the first-year rate at 1.99 percent through the builder's in-house lender.

The resale. Five hundred thousand dollars. Established street, mature landscaping, move-in ready. No incentive. That buyer takes today's market rate as-is, because the seller isn't buying anybody's rate down.

Both buyers put 20 percent down. The new build buyer borrows $480,000. The resale buyer borrows $400,000, eighty thousand less. Watch the payment anyway.

How Do the Monthly Payments Compare, Year by Year?

The $600,000 new build costs less per month than the $500,000 resale in every year of the loan, once the builder's rate buydown is factored in.

Rates: 30-year resale rate per Bankrate and Freddie Mac, August 2026. Builder buydown structure reflects current in-house lender promotions from national builders in the Las Vegas valley, August 2026.

Year one, the pricier house costs about $812 less per month. That's roughly $9,700 kept in year one alone.

Year two, after the buydown steps up, it still costs about $562 less per month.

Year three and every year after, with the buydown fully expired and the permanent rate in place, it still costs about $294 less per month.

The buyer chasing the lower sticker price pays more every single month for thirty years.

What Does a Builder Rate Buydown Actually Do?

A builder rate buydown is a program where the builder's in-house lender pays money upfront to temporarily lower your interest rate, usually stepping up over one to three years before landing on a permanent rate. I want to be blunt about the mechanics, because this is where people get sold a story.

The 1.99% is temporary

It is a first-year discount, not your mortgage rate. A typical builder buydown here gives you a low rate in year one, a higher rate in year two, and the permanent note rate from year three forward. Anyone telling you they "got a 1.99 percent mortgage" is leaving out the second half of the sentence.

You still qualify at the full rate

The lender does not underwrite you at the teaser rate. They underwrite you at the permanent note rate. If that higher payment breaks your debt-to-income ratio, the buydown does not rescue the file. A buydown is a cash-flow cushion for the first two years, not a qualification workaround.

The incentive is not a check

That eighty-five thousand dollar figure is a stack of credits, and a large share of it is what funds the buydown itself. These programs almost always require using the builder's in-house lender. Read the terms before you anchor to the headline number.

What Costs Are Missing From the Payment Table?

The payment table above shows principal and interest only. Property taxes, homeowners insurance, and HOA dues all sit on top, and two of those line items catch California buyers off guard on Nevada new construction.

• HOA dues are often higher in newer master-planned areas, and in some cases you're in two associations instead of one: a sub-association and a master association.
• Some newer areas carry special assessment bonds attached to the property tax bill. It shows up on the tax line, but it isn't a tax. Ask for the full itemized cost sheet before you compare anything.

A cheaper mortgage payment paired with a much higher HOA is not automatically a win. Compare total monthly cost, not just the loan payment.

When Does Resale Still Beat New Construction?

Resale still wins for buyers who need to close fast, want a mature lot, are paying cash, or plan to sell within two or three years. I sell both, and resale is the right answer for a lot of people.

Choose resale if you need to close fast, since a new-build timeline usually will not accommodate a thirty-day move. Choose resale if you want mature trees, a larger lot, and a shorter drive to the center of the valley, since most new construction sits on the outer edges. Choose resale if you're paying cash, because rate incentives are worth nothing to you and price negotiation is worth more.

Choose resale if you plan to sell within two or three years. The monthly savings need time to outrun your closing costs. And if you can't qualify at the permanent note rate, the new-build math in this post isn't available to you at all.

What Four Questions Should You Ask Before You Compare Any Listing?

Before you compare a single listing, answer these four questions in order.

1. What is my year-three payment? If year three doesn't work, the deal doesn't work. Ignore the teaser rate entirely.
2. What is my full monthly cost? Add the loan payment, property taxes, insurance, and every HOA. Get it on paper.
3. How long am I holding? Under three years, the math gets thin. Over five years, the spread compounds in the new build's favor.
4. What does the resale side look like at today's market rate with zero incentive? Run both scenarios, not just one.

Why Does This Math Work Right Now, in August 2026?

This math works right now because two things are true at the same time: mortgage rates are elevated and builders are sitting on inventory they need to move.

Rates have been running in the high 6 percent range for weeks, with no clear signal of a near-term drop (Bankrate, Freddie Mac, August 2026). So the "I'll buy when rates fall" plan currently has no visible finish line.

Meanwhile, builder promotions like the one in this post's example typically run on a contract deadline tied to a specific closing window, and the terms usually reset or disappear once that window closes. Builders are manufacturing the low payment the market isn't giving anyone on its own. That's a temporary condition tied to a specific promotion, not a permanent feature of the market.

If your year-three number works, you have a real decision on your hands. If it doesn't, you just saved yourself a mistake. Either way, run both columns before you sort by price again. In this market, the house that looks more expensive on paper can still be the one that wins on the monthly bill. The House Always Wins.
