(NewsNation) — New York City’s new tax on second homes has property owners furious, especially after the city published a searchable online database identifying tens of thousands of properties that could be subject to the surcharge.

Author and podcast host Scott Galloway was once a supporter of the tax, having voted for Mayor Zohran Mamdani. However, Galloway shared on his “Pivot” podcast Friday that he wasn’t thrilled when he saw the mayor’s office had him on the list.

“I’ve been doxxed,” he told his co-host, Kara Swisher. “Mayor Mamdani has decided to release a list of the 950,000 residences with addresses and names that might be eligible for his pied-à-terre tax. He’s taken a legitimate source of tax revenue, and he’s turning it into a wanted poster.”

Galloway isn’t the only one worried about the list. Some say having their information so readily available could create potential safety concerns.

Real estate insiders have warned the annual property tax surcharge on secondary homes worth more than $5 million could trigger a major luxury exodus with wealthy buyers unloading their high-end properties rather than paying a surcharge.

However, “Owning Manhattan” star and licensed real estate agent Peter Zaitzeff appeared on “Jesse Weber Live” Monday and said he doesn’t believe that will happen.

“We’re not seeing a mass exodus. If anything, the market still remains strong,” Zaitzeff said. “Of course, they’re going to think twice, but there’s no panic selling going on.”

Mayor Mamdani and New York Democratic Gov. Kathy Hochul said when they first announced the pied-à-terre tax in April that they expected it would raise more than $500 million, helping narrow the city’s $5.4 billion budget deficit. Zaitzeff believes it could instead cost the city in the long term.

“What it’s doing is it’s forcing pied-à-terre buyers to buy properties of less value,” Zaitzeff said. “These are buyers that are already paying significant mansion taxes and transfer taxes when they buy properties. They’re also trading these things frequently. So those taxes that the city gets are every three or four years when somebody buys a larger property.”

The city has given homeowners until Sept. 18 to apply for an exemption from the tax surcharge by proving the home is their primary residence. Zaitzeff said his clients are already reaching out to top real estate attorneys and accountants for help securing exemptions, which he argues will end up costing the city even more.

“This is all going to be backlogged and the administration fees of this. You’re talking; he wants to raise $500 million? Forget about it. The administration fees alone are going to cut deeply into that.”
