Three Months Free Rent: Why Landlords Are Courting Tenants Amid a Construction Boom

In Nashville, Tennessee, apartment hunters don’t just browse listings — landlords come to them. Mason Comans, a local renter, recently received texts from property managers offering one month of free rent. Then two. Then three. “I even saw some places doing three months, three and a half months free,” Comans told NPR.

This is what happens when a historic construction boom collides with cooling demand. After years of punishing rent increases, the U.S. rental market is undergoing a dramatic shift — but whether that shift amounts to genuine relief or a temporary pause depends largely on where you live.

The Supply Wave That Changed Everything

The root cause of today’s renter-friendly conditions is simple economics: an extraordinary surge in apartment supply. In 2024, the United States completed approximately 608,000 multifamily units — the highest number in 38 years, according to the National Association of Home Builders. That wave of new construction pushed the national rental vacancy rate to 7.3% at the start of 2026, the highest level in a dozen years, as tracked by the Federal Reserve Bank of St. Louis.

With more apartments competing for fewer tenants, landlords have been forced to sweeten the deal. In April 2026, a record 39.8% of rentals on Zillow offered move-in incentives, from waived fees to months of free rent. National asking rent growth slowed to just 1.9% year-over-year, and according to Realtor.com, rents actually declined 1.5% year-over-year in January 2026 — the 29th consecutive monthly drop.

“Renters, this is your year,” said Kara Ng, senior economist at Zillow. “There’s a lot of apartment buildings hitting the market all at once. And property managers are trying to fill it, and they’re doing it with freebies.”

A Tale of Two Rental Markets

But the national numbers mask a stark geographic divide. The construction boom was concentrated in Sun Belt cities that saw explosive population growth during the pandemic. Nashville, Austin, and Phoenix are now awash in concessions. Austin rents have fallen nearly 20% from their 2022 peak, and vacancy rates in some Sun Belt markets exceed 11%.

Meanwhile, renters in other parts of the country are seeing a very different picture. Chloe Troub, a Chicago renter paying $1,600 for a one-bedroom apartment, called the idea of a “renter’s market” insulting. “Just given the cost, the sheer cost, of putting a roof over your head right now,” she told NPR. Chicago rents rose 5.4% year-over-year in April, driven by tight supply and sustained demand. The Northeast and Midwest, where new construction is far more limited, are projected to see 3-5% rent growth through 2026.

The Fine Print on Free Rent

Even in markets where incentives abound, there are important caveats. Move-in concessions are temporary by nature. “As soon as they get you locked in, you’re still getting rent increases every year,” warned Michelle Becker, a broker with Adaro Realty in Nashville.

Comans, the Nashville renter, has moved four times in five years to chase deals. His strategy works — for now. But it comes with moving costs, instability, and the risk that the market could shift beneath him.

And despite the recent moderation, rents remain painfully high by historical standards. The average rent has surged 36.9% since the beginning of the COVID-19 pandemic, according to Zillow. Even with incentives, Comans pays $1,800 a month. “It is a lot of money,” he said. “It’s not cheap at all.”

The Affordability Crisis Beneath the Surface

The headline numbers — falling rents, rising vacancies — obscure a deeper structural problem. According to the Harvard Joint Center for Housing Studies, 22.7 million renter households — 49% of all renters — spend more than 30% of their income on housing. The loss of affordable units has been staggering: 9.3 million apartments renting for under $1,400 a month disappeared between 2014 and 2024, as new construction overwhelmingly targeted the luxury segment.

Housing economist Brad Hunter, writing in Forbes, described 2025 as “historically painful” for landlords, with vacancy rates exceeding 8% and negative rent growth. But he warns that the pendulum is already swinging back. Multifamily construction starts have fallen roughly 50% from their 2022-2023 peaks, meaning the pipeline of new supply will dry up by late 2026 or 2027.

What Comes Next

The current window of renter leverage may be closing. As the supply of new apartments tapers, landlords are expected to regain pricing power. Industry projections call for national rent growth to rebound to 2-3% in 2026 and accelerate further in 2027.

For renters like Comans, the strategy is clear: keep moving to keep deals alive. For the 22.7 million households already struggling with housing costs, the calculus is more urgent. The construction boom has provided genuine relief in some markets, but it has not solved — and may have temporarily masked — the nation’s deepening affordable housing crisis.

As Ng put it, for households squeezed by rising costs on everything from gas to groceries, “Rent is the place giving you that breathing room.” The question is how long that breathing room will last.
