Builder confidence has dropped to a one year low, two in three builders are using sales incentives and the average 30 year mortgage rate is back above 7%. The American market is showing that building homes and selling them are two very different problems.

America’s home builders are still putting up houses. The harder job right now is selling them at a price that works for the builder and the buyer at the same time.

The latest figures from the US Census Bureau and the National Association of Home Builders show an industry still starting homes at a similar pace while completions fall, confidence slides, discounting spreads and mortgage rates climb back above 7%. It is a clear case study in what happens when the cost of producing a home and the cost of financing one pull in opposite directions.

Housing starts dipped slightly in August while permits slipped

Privately owned housing starts ran at a seasonally adjusted annual rate of 1,275,000 in August 2026, according to the Census Bureau. That was 2.6% below the revised July figure of 1,309,000 and 1.2% below August 2025.

Single family starts were the bright spot on paper, rising 7.6% on July to an annual rate of 918,000. The Census Bureau’s own margin of error on that monthly change is plus or minus 14%, which means the rise is not statistically significant. It is a signal worth watching, not a trend to bank on.

Building permits, the best early read on future starts, fell 2.7% on July to an annual rate of 1,394,000. They were still 3.5% higher than a year earlier, so the pipeline has not collapsed. It has simply stopped accelerating.

Further along the pipeline, completions ran at an annual rate of 1,128,000, which was 27.1% below August 2025. Around 1,271,000 homes were under construction at the end of the month.

Builder confidence is at its lowest point in a year

NAHB’s Housing Market Index fell three points to 32 in September, the lowest reading since September 2025. None of its three components improved. Current sales conditions fell four points to 35, expectations for the next six months dropped six points to 37, and the measure of prospective buyer traffic held at a weak 23.

NAHB put the fall down to higher mortgage rates, worsening labour shortages and rising material costs. Its chief economist also pointed to tight lending conditions and elevated land, labour and construction costs.

Regionally, the three month averages ranged from 44 in the Midwest to 28 in the West, with the Northeast at 39 and the South at 31. Any reading below 50 means more builders see conditions as poor than good, so no region is in positive territory.

What the Housing Market Index measures

NAHB’s monthly survey asks member builders to rate current sales of new single family homes, expected sales over the next six months and the traffic of prospective buyers. The answers are combined into an index where a reading above 50 means more builders see conditions as good than poor. At 32, American builders are firmly on the pessimistic side of that line.

Price cuts and incentives have become the default sales tool

The most telling figures in the September survey are about how builders are selling. According to NAHB, 38% of builders cut prices in September, up from 35% in August. The average cut held at 6% for the sixth consecutive month.

Sales incentives are even more widespread. Two in three builders (66%) used them in September, up from 63% in August and the highest share since December.

Incentives and price cuts do different jobs. A price cut resets the value of every comparable home on the estate. An incentive can protect the headline price while still bringing down the buyer’s cost. Incentives running well ahead of outright cuts suggests builders are working hard to hold their price points while still getting deals over the line.

Neither option is free. Both come straight out of margin at a time when land, labour and materials are not getting any cheaper.

The monthly repayment is where the deal falls over

The affordability squeeze shows up most clearly in borrowing costs. Freddie Mac’s weekly mortgage survey put the average 30 year fixed rate at 7.03% in the week to 24 September 2026, up from 6.95% the week before and 6.30% a year earlier.

For a buyer, that increase lands directly on the monthly repayment. For a builder, it shrinks the pool of buyers who can qualify for a given house at a given price. That is how a builder can have a well located, well built product and still struggle to move it.

Census data on new home sales shows the tension. Sales ran at an annual rate of 684,000 in August, up 6.4% on July but 2.0% lower than a year earlier. The monthly rise again sits inside a wide margin of error. The median sale price was US$393,700, down 5.8% on August 2025, although that fall is also inside the Census margin of error.

A softer median price while costs rise points to pressure on margins. A lower median can reflect discounting, a shift in the mix toward cheaper homes, or both. The Census figures do not separate the two, but either way the builder is absorbing the gap between what a home costs to deliver and what a buyer can pay.

Months of supply has eased, but the stock of homes has not

There were 483,000 new homes for sale at the end of August, unchanged on July. At the current sales pace, that is 8.5 months of supply, down from 9.0 months in July and the same as a year earlier. Earlier this year, when supply for May was first reported above ten months, builders pulled back on purpose. That May figure has since been revised down to 9.2 months.

The easing in months of supply came from a better month of sales, not from fewer homes on the market. Stock has not come down, and buyers have not suddenly found more borrowing capacity. Builders are still carrying the same inventory into a market where the monthly repayment keeps rising.

Building more homes does not solve affordability on its own

The standard response to a housing affordability problem is to build more. But building more homes does not solve an affordability problem if the finished product sits outside what buyers can borrow.

Building more homes does not solve an affordability problem if the finished product sits outside what buyers can borrow.

Builders have levers. They can change home size, specification, lot selection, construction method and the mix of product on an estate. They can use incentives to bridge the gap for individual buyers. What they cannot easily change is the cost of land, labour, materials and finance that sits underneath every house before a single buyer walks through the door.

That is why the American story in 2026 is less about whether homes can be built and more about whether they can be built at a price enough buyers can actually carry.

THE GOOD BUILDER TAKE

The US market is a live example of something every builder knows but rarely sees this clearly in the numbers. Volume and viability are not the same thing. When two in three builders need incentives to close a sale, the constraint is not site capacity. It is the gap between what a home costs to deliver and what a buyer can borrow, and that gap rarely shows up in headline starts figures until it has already eaten the margin.
