Builder confidence dropped again in July. The National Association of Home Builders/Wells Fargo Housing Market Index slipped to 42, down from 43 the previous month — and any reading below 50 signals that more builders view conditions as poor than good. That’s not a headline number that shocks the market on its own, but when you stack it against months of consecutive sub-50 readings and rising input costs, it starts to tell a story that matters directly to anyone trying to buy a new construction home in the Phoenix metro area.
What the Index Is Actually Measuring
The HMI captures three things: current single-family sales conditions, sales expectations for the next six months, and buyer traffic. All three components were soft in July. Current sales conditions came in at 46, future expectations at 48, and prospective buyer traffic — arguably the most important forward-looking number — sat at just 27. That traffic figure is the one that keeps builders up at night. Foot traffic through model homes drives orders, and orders drive construction starts.
When traffic slows, builders face a choice: keep building on spec and hope demand returns, or pump the brakes. Right now, most of the larger national builders operating in the Phoenix metro — companies with communities spread across Surprise, Queen Creek, and Buckeye — are pulling back on starts while working through existing inventory.
Why Affordability Isn’t Getting Better Fast Enough
Here’s the core problem. Mortgage rates have been hovering in the mid-to-high 6% range for most of 2025, and despite hopes for Fed rate cuts, the cuts haven’t translated into meaningful mortgage relief. The Fed has held rates steady more than once this year, and the bond market hasn’t exactly rolled out the welcome mat for lower rates either.
Run the numbers on a typical new construction home in the East Valley — say a 2,100-square-foot home in a Gilbert or Chandler master-planned community priced at around $490,000. At 6.75%, your principal and interest payment alone sits near $3,180 per month. Add HOA fees, property taxes at Arizona’s assessment rates, and homeowner’s insurance, and you’re well past $3,700 a month. That’s a serious ask for a household earning $95,000–$110,000 a year, which is roughly the median household income for many of these suburbs.
Builders know this. They’ve been throwing incentives at the problem — interest rate buydowns, closing cost credits, free upgrades — but those tools have limits. A 2/1 buydown gets a buyer into the home, but year three brings the rate back up.
The affordability squeeze is real, and it’s documented. May’s new-home sales data already showed a shrinking pool of affordable inventory, and the July builder sentiment numbers suggest that trend hasn’t reversed.
What This Means for the Phoenix New Construction Market Specifically
Phoenix is in a complicated spot. On one hand, this is one of the most active new construction markets in the country — dozens of master-planned communities across the West Valley and Southeast Valley were platted and approved during the boom years of 2020–2022. Builders committed to land, infrastructure, and entitlement costs when conditions were very different.
On the other hand, buyer traffic has softened. Inventory of completed but unsold new homes has crept up across the metro, particularly in price points above $550,000. Some communities in the Buckeye corridor and far northwest Phoenix have seen days on market stretch well past 90 days on spec homes.
A few specific dynamics are worth watching:
- The spec home glut at entry-level prices. Builders targeting the $350,000–$430,000 range are still moving product, but margins are thin after rate buydowns.
- The move-up segment stalling. Buyers who could trade up from a $400,000 resale into a $600,000 new home are often locked in by their existing low mortgage rates. The math to move doesn’t work.
- Labor and materials costs staying stubbornly high. Lumber prices have moderated from pandemic peaks, but HVAC equipment, electrical components, and skilled trade labor remain expensive. Builders can’t cut their way to affordability.
The build-to-rent sector has partially filled the demand gap — projects like Avilla Foothills in Surprise reflect what happens when for-sale demand cools and institutional capital steps in to convert that supply into rentals.
What Buyers Should Actually Do With This Information
A falling HMI doesn’t mean stop shopping for new construction. It means the leverage has shifted — and it’s shifted toward buyers. Builders sitting on completed inventory are motivated. That’s a negotiating environment you want to be in.
Here’s how to approach it:
- Ask what the builder’s current incentive package is before you start negotiating anything else. Buydowns, free upgrades, and closing cost assistance are often baked in already — don’t leave them on the table.
- Look at communities that have been open 12 months or longer. Newer communities are still optimizing pricing; older phases are often where the deals are.
- Get a real estate agent who tracks new construction actively. Builder reps work for the builder. Period.
- Don’t ignore resale as a comparison point. With home asking prices posting notable drops, the price gap between new and resale is narrowing. New construction’s premium has to justify itself.
The Bottom Line
Builder confidence at 42 is a signal, not a crisis. It tells you that the people building homes are cautious, that they’re adjusting to a market where buyers are stretched, and that the supply spigot is being turned down incrementally. For the Phoenix market, that means fewer future starts — which is actually a longer-term price support — but more immediate opportunity in deals on existing inventory.
If you’re in the market for new construction right now, this is a moment worth acting on. Builders want to close deals before end-of-quarter. The incentives available today may not exist six months from now once rates eventually do come down and buyer traffic recovers. Move with information, not urgency — but don’t sit this one out.
