Phoenix Is Absorbing Apartments Faster Than It's Building Them

National apartment rents rose in August for the first time in several years, and the reason wasn't a demand surge. It was the supply wave finally thinning out. The average advertised rent nationally climbed $2 a month, reaching $1,773, according to Yardi Matrix. That is a move of roughly a tenth of a percent, almost nothing on its own, and worth attention only because of the direction. Phoenix's annual rent number is still negative. But the Phoenix figures sitting underneath that line are doing something more interesting.

The National Number Turned Because Lease-Ups Are Clearing

Annual rent growth accelerated 20 basis points to 0.4%, its fastest pace in nearly a year. Yardi counted 1.2 million units nationally in lease-up at the start of August, down from a 1.4 million peak in early 2025. That is still roughly double the market average of the previous decade, but it is headed the right direction. Starts and deliveries have fallen by one-third from their 2023 and 2024 cycle highs. Sixteen of Yardi's top 30 markets posted monthly rent gains in August.

Two Rent Numbers, Two Different Markets

Yardi puts Phoenix advertised rents down 1.6% year over year and forecasts a 2.8% decline for 2026. Northmarq describes a different market entirely: absorption outpacing deliveries, vacancy falling to a three-year low in the first half of 2026, and modest rent growth in each of the first two quarters of the year. Both readings are accurate. They are measuring different things. Advertised rent tracks what properties are asking, and in Phoenix that number is dominated by lease-up communities discounting to fill units. It says little about what an occupied, stabilized asset is achieving.

The Lease-Up Overhang Is What Weighs on the Headline

Phoenix carried 42,286 units in lease-up at the start of August, second only to Dallas and equal to 9.8% of its stock, the third-highest share behind Charlotte and Austin. Those are the units competing on price. Yardi notes that Sun Belt declines continue to moderate, and Phoenix was not among the markets it named as falling month over month in August.

The Clearing Is Measurable, Not Theoretical

Yardi's analysis found rent growth correlates strongly with lease-up share, and the markets furthest along that path show what the descent looks like. Austin's lease-up percentage peaked at 18.3% in June 2025 and stood at 11.0% in August. Nashville peaked at 14.2% in March 2024 and has reached 8.9%. Yardi is candid that the percentage may need to fall further before advertised rents regain normal growth, but the direction in most of these markets is no longer in question.

Demand Held While the Pipeline Emptied

None of this reflects renters leaving. Northmarq reported nearly 6,000 units absorbed in the second quarter and more than 12,400 through the first half, with absorption averaging above 5,600 units per quarter since the start of 2025. Deliveries went the other way. Fewer than 6,700 units came online in the first half of 2026, the lightest midyear total since 2022, and units under construction have declined in seven of the past eight quarters to their lowest level since early 2021. Northmarq expects second-half deliveries near half the more than 14,000 units delivered in late 2025. Greater Phoenix completed more than 65,000 units across the preceding three years. That stretch is over.

The Bigger Picture

The negative headline on Phoenix rents is a lease-up number, and it is dated. It prices off units delivered in 2023 and 2024 that are still filling, while vacancy across the market has fallen to a three-year low and existing properties have posted growth in both quarters of 2026. Yardi's forecast of a 2.8% decline is a real headwind, and the advertised figure will keep lagging for several more quarters. But the pipeline that would extend the pressure has already shrunk to a five-year low, and the markets outperforming today are simply the ones that finished absorbing first.

For Neighborhood Ventures, the shift is already showing up in our own portfolio. Our properties have stayed well occupied through the supply wave, and rents have held stable across the past three years. In recent months we have started to see concessions burn off and rents move slightly positive. That is what the front edge of a supply correction looks like from inside a portfolio.
