Higher Rates Are Shrinking the Apartment Pipeline, Not the Renter Pool

Rate hikes are supposed to cool demand. Rental housing economist Jay Parsons argues that in apartments they are doing the opposite of what the Fed intends. In his October 26 newsletter, Parsons makes the case that higher rates are choking off new construction while renter demand keeps climbing, a combination that could push rents higher in 2027 and 2028. He calls it "no sure thing." The data behind it is still worth an investor's attention.

Rates Are Hitting the Wrong Side of the Market

The Fed raised its benchmark rate in September for the first time since 2023 and held it at 3.75% to 4% on October 28. Renters have not pulled back. CoStar data shows 2026 on track to be the third-best year for apartment absorption since 2000, and RealPage ranks it sixth. Part of the reason is the rate itself. RealPage estimates the 30-year mortgage would need to fall to about 5.5% before buying beats renting, while Freddie Mac's rate sits at 7.24%, leaving ownership roughly $930 a month more expensive, as summarized by CRE Daily.

The Pipeline Is Emptying

Construction is where higher rates are biting. About 442,395 new apartments will open nationally in 2026, down 27% from 605,768 last year and below the ten-year average of roughly 466,000 for the first time in four years, according to RentCafe's analysis of Yardi Matrix data. Parsons' review of RealPage data since 2010 found that apartment starts fell 11% in the year after a Fed hike and 17% over two years. Lenders are reinforcing the trend. The Fed's October senior loan officer survey showed banks tightening standards on construction and multifamily loans.

Fewer Starts Has Meant Faster Rent Growth

In the same RealPage data, whenever trailing twelve-month starts topped 450,000 units, rent growth stalled within two and a half years, averaging 0.2%. The reverse is now playing out in markets that finished their supply waves early. Boise, where RentCafe projects completions down 59% this year, is posting rent growth in the 8% to 10% range, per Parsons. Austin's rents went from down 8% year over year in March to slightly positive by September. Apartments.com lifted its national rent growth forecast for the fourth quarter of 2027 to 2.6% from 1.9%.

Phoenix Is Near the Turn, Not Past It

Phoenix sits earlier on that curve. Asking rents fell 0.3% in September after a 0.1% dip in August, a combined 0.4% decline compared with 1% over the same two months of 2025, according to CoStar's Connor Devereux. Nearly three-quarters of Phoenix properties were still offering concessions in August, so annual rents remain negative. But the local construction pipeline has fallen by more than half from its peak, and Parsons lists Phoenix among the markets with the biggest improvement in rent momentum this year.

The Case Against

The thesis has real counterweights. Starts remain well above early 2010s levels, which could cap how far rents run. Harvard's Joint Center for Housing Studies recently warned that slower immigration could sharply reduce renter household growth. And rates may not stay high. The 10-year Treasury fell 6.4 basis points to 4.886% after Tuesday's midterms. Lower rates would eventually improve development math, but a project financed next year still takes two to three years to deliver.

The Bigger Picture

Monetary policy works quickly on demand for most goods and slowly on housing supply. That mismatch suggests the apartment market is heading into a period where fewer units are coming and renters are staying longer. Phoenix has not turned positive yet, but the conditions that preceded rebounds in Boise and Austin are now forming there.

For Neighborhood Ventures, a shrinking pipeline matters most for existing buildings bought well below replacement cost. When high rates stop new projects from penciling, older Phoenix properties face less new competition and gain room to grow rents as demand holds. We are already seeing the 10-year Treasury ease, slipping below 5% after peaking near 5.3% in early October, and we will be tracking the long-term effects on both financing and new supply. That's the kind of setup we want to be buying into.
