Mamdani’s affordability revolution stumbled as rent costs soar to record highs

New York City Mayor Zohran Mamdani rode his promise to make one of America’s most expensive cities more affordable all the way to City Hall.

But for New Yorkers hunting for an apartment, rents have never been higher.

The citywide median asking rent reached $4,200 in June, up 5% from a year earlier and the highest recorded by StreetEasy since it began tracking the market in 2010.

In Manhattan — the most densely populated NYC borough — the median cost of monthly rent climbed 5.1% to $4,965.

At the same time, apartments are becoming harder to find.

The number of rentals available across the city fell 1.4% from a year ago, while Manhattan saw a 4.4% drop.

It was even more dire for larger apartments in Manhattan , where the number of available two-bedroom units fell 9.3% and three-bedroom units dropped 11%.

Simply put, there are not enough apartment units to meet demand, and costs are reflecting that squeeze.

TRUMP'S HOUSING CHIEF PAINTS A GRIM PICTURE FOR HOMEOWNERSHIP IN ONE MAJOR AMERICAN CITY The rental unit shortage presents an early test for Mamdani’s affordability agenda in New York.

While the socialist mayor has pledged to dramatically expand the city’s housing supply, his push to freeze rents on roughly 1 million rent-stabilized apartments has drawn warnings from economists who say the policy could discourage investment and make an already tight housing market even tighter.

Adam Lehodey of the Manhattan Institute told Fox News Digital that rent increases on rent-stabilized apartments have failed to keep pace with inflation for years, even as the costs of maintaining buildings have continued to rise.

As a result, he said, "slowly but surely, landlords have less to invest in their properties." He argued that this growing gap is leaving some building owners increasingly unable to cover basic operating expenses, which can lead to deferred maintenance and reduced investment in the city’s existing housing stock.

Lehodey also pointed to a second dynamic in the rent-stabilized market: tenants paying below-market rents have a strong incentive to stay in place, which reduces turnover and makes those apartments harder for prospective renters to find.

"People who are looking for apartments can't find apartments," Lehodey said.
