New York City Mayor Zohran Mamdani is facing criticism after his administration published a searchable database listing the names and addresses of property owners who could be affected by the state’s new pied-à-terre tax, prompting opponents to raise concerns about privacy, public safety, and the potential economic impact.
According to the New York Post, the database was released by the city’s Department of Finance and identifies owners of unoccupied, non-primary residences valued at more than $1 million across the city’s five boroughs.
If you have a second home in New York City worth more than $5M, check your mailbox when you’re back in the five boroughs — because you’ve got mail.
Today, we sent notification letters to property owners, letting them know that our new pied-à-terre tax is coming soon.
The best…

The tax is intended to apply to luxury second homes, but questions have emerged over the scope of the database. Crain’s New York Business previously estimated that roughly 31,000 properties would be subject to the tax. The Post, however, reported that the published database contains information connected to more than 960,000 residences and individuals, a figure far larger than earlier projections.
The publication of homeowners’ names and addresses quickly drew criticism from Republican officials and business leaders.
Staten Island Republican Council Minority Leader David Carr called the move “reckless and foolish,” arguing that publicly identifying property owners creates unnecessary risks.
What is the “fair share” of your many constituents who PAY NOTHING, Comrade Mayor?

Steve Fulop, a nonprofit business executive, said many of those listed are not ultra-wealthy individuals but people who invested in New York real estate after years of work.
“Most of the people on that list aren’t billionaires by any stretch—they’re people that believed in NYC, worked hard and bought a second home,” Fulop said. “All this does is make people feel less safe in their own city, and less welcome in it.”
Some critics also pointed to broader concerns about security for affluent residents. They referenced the December 2024 killing of UnitedHealthcare CEO Brian Thompson in New York City, a case in which Luigi Mangione has been charged, arguing that publicly available personal information could heighten concerns among property owners.
In a reversal for the predatory communist, those homes just dropped in value.
They are no longer worth more than $5 million because people who can afford that price do not want to hand their money to a massively corrupt and wasteful city government.— Happy Granddadddddd (@PlotWeaver) July 24, 2026
Opponents also warned that the policy could discourage investment in New York’s luxury housing market and encourage buyers to look elsewhere.
“All the mayor is doing is tanking the luxury home market in NYC and sending millions of dollars in real estate business to other states,” Carr said. “But the upside is Mamdani is a shoo-in for ‘Realtor of the Year’ in Texas and Florida.”
The controversy intensified after Mamdani promoted the new tax on social media.
Consequences of this policy:
– More money leaves your state
– More jobs leave your state
– No incentive for the wealthy to buy a property in NYC
– Property value drops
– More construction workers lose jobs
– Realtors lose income.What’s your point with this policy?

Writing on X last week, the mayor told owners of luxury second homes to “check your mailbox.”
“The best city in the world deserves the best parks, libraries, and schools in the world,” Mamdani wrote. “That’s only possible when we all pay our fair share.”
The post generated a wave of criticism from users who argued that higher taxes and public disclosure of property owners’ information could discourage investment rather than increase revenue.
