Why new construction can cost less right now (and when it doesn't)

These are national numbers

In August 2026 the typical new house in the U.S. sold for less than the typical existing home. Builders have also been cutting prices and paying for incentives more often. That can make a new house cheaper to buy, at least for the first couple of years. It doesn't always hold up, and the details are in your contract.

New homes vs. existing homes

The Census Bureau and HUD put the median sales price of new houses sold in August 2026 at $393,700. That's 0.4% above July ($392,200) and 5.8% below a year earlier ($417,900). The average was $478,700. These come from a sample survey, and the next release is due Oct 27, 2026.

For existing homes, the National Association of REALTORS® reported a median of $429,100 in August, up 1.6% from a year before. Single-family homes alone were $434,800. NAR's South region was $366,500. NAR counted 4.9 months' supply of homes for sale.

Subtract, and the national new-home median is $35,400 below the existing-home median. Against single-family existing homes the gap is $41,100.

Don't lean on that gap too hard. The two medians describe different houses in different places, so they aren't like-for-like. They're also counted differently. Census counts a new house as sold when a contract is signed or a deposit is taken, even before it's built. NAR counts existing homes at closing, and its overall median includes condos and townhomes.

NAR figures are quoted from its September 10, 2026 news release, with a link. NAR's terms don't allow its data tables to be copied, so we don't reproduce them.

Builders are cutting prices and adding incentives

NAHB's monthly builder survey with Wells Fargo found 38% of builders cut prices in September, up from 35% in August. The average cut stayed at 6%. And 66% used sales incentives, up from 63%. That's the highest share since December, when it was 67%. Builder confidence fell to 32 on NAHB's index (NAHB, Sep 16, 2026).

That's national too. Incentives vary by builder and by house, and we have no data on what Oklahoma builders are offering. The only number that counts is the one written into your contract.

What a builder-paid buydown is worth

A common incentive is a 2-1 buydown. The builder pays into an account at closing, and that account covers part of your payment for two years. Year 1 is figured at 2 points under your note rate and year 2 at 1 point under. From year 3 on you pay the full payment.

The account is usually sized as the sum of those monthly differences. That's what the buydown calculator works out.

Here's a $350,000 houseExample, change it in the calculator with the 30-year average from Freddie Mac's Primary Mortgage Market Survey®, 7.40% for the week of Oct 8, 2026, as the note rate. That's a national average, so your quote will be different. Payments are principal and interest only.

The 5% down payment is only an example. The FHA loan is bigger because it includes the 1.75% upfront mortgage insurance premium. On the conventional loan, a builder paying $7,889 for a 2-1 buydown saves you $435.07 a month in year 1 and $222.36 in year 2. After that it's gone. FHA works the same way with slightly bigger numbers ($8,154).

A permanent buydown is different. You or the builder pay discount points at closing for a lower rate on the whole loan. A point costs 1% of the loan. How much rate a point buys is up to the lender, so get it in writing and check the break-even in the calculator's points mode.

Ask the builder what the incentive is worth in dollars. Then ask your lender to show you the payment with the buydown and with the same dollars taken off the price instead. A price cut shrinks the loan itself, so it keeps paying off after year 2.

Insurance on a new roof in Oklahoma

Insurance is a big piece of the payment here. Oklahoma's statewide average in LendingTree's 2026 study was $5,298 a year, and that's only an average.

The Oklahoma Insurance Department says homes with a FORTIFIED Home designation get a discount on the wind portion of the premium. Each insurance company sets its own. OID's one-sheet lists discounts of up to 42% on wind and hail premiums for a FORTIFIED High Wind & Hail roof, with these examples: State Farm 30%; Union Mutual Insurance Company 25%; National Security Fire and Casualty 42%; Shelter Insurance Company 14%; Nationwide Mutual Fire IC 6%. Those come from 2018 rate filings. OID calls the list a representative sample and says discounts can change.

A new house can be built to the FORTIFIED standard from the start, but don't assume it is. Ask the builder if the house will get a FORTIFIED designation. Then ask your agent what discount it would earn with your company. The state's Strengthen Oklahoma Homes program pays up to $10,000 per approved household toward upgrading a roof to FORTIFIED, on new or existing owner-occupied homes with a homestead exemption. Applications open statewide at noon on October 12, 2026 (OID).

Insurers often price the age of the roof too. We don't have reliable data on how much that moves a premium, so get quotes on the actual address before you decide. Spring hail and wind season is when you find out what your deductible is.

When new construction doesn't come out ahead

A buydown only lasts two years. If the full payment in year 3 is more than you can carry, the deal wasn't cheaper. New subdivisions can also come with HOA dues, and the buydown doesn't touch those.

So run the full payment, not the year-one payment. Use the mortgage calculator with the full note rate, then the buydown calculator for the first two years. The affordability calculator and the home insurance calculator help with the rest.
