New York City Mayor Zohran Mamdani's recent proposal to tax luxury second homes owned by the ultra-wealthy has drawn sharp criticism from political and business leaders, including former Boca Raton Mayor Scott Singer and Citadel CEO Ken Griffin. The plan, which Mamdani celebrated, is expected to generate at least $500 million annually in revenue for the city [1]. However, Singer argues that the policy 'makes no sense' and will only exacerbate the ongoing exodus of business owners and job creators from New York to states like Florida [1].
Singer, who is currently running for Congress in Florida's 25th District, contends that Mamdani's 'tax the rich' platform and proposals to increase property taxes—reportedly by 11% for some part-time residents—will drive more capital away from New York, depress property values, and reduce job opportunities [1]. He points to recent statements by Ken Griffin, who pledged to increase his investment in Florida in response to the new taxes on the wealthy imposed by Mamdani [1]. Singer maintains that the trend of businesses and wealthy individuals relocating to Florida will 'continue naturally' as a result of these policies [1].
In contrast, Mayor Mamdani has dismissed concerns about an exodus of wealthy residents as 'imagined.' He notes that during his time as a state legislator, similar warnings were issued when taxes on millionaires were previously increased, yet the number of millionaires in New York City actually grew after the tax hike [1]. Despite this, New York City's population declined in 2025, the year before Mamdani took office, resulting in a net loss of about 12,000 people [1].
Singer advocates for an alternative approach focused on 'creating job growth, lowering taxes, shrinking government and allowing the free market to continue to attract jobs to attractive places' [1]. Fox News Digital reached out to Mamdani’s office for further comment, but no additional statements were provided in the article [1].
CONCLUSION
Mayor Mamdani's luxury home tax proposal has sparked significant debate, with critics warning of continued capital flight and economic decline, while Mamdani maintains that fears of an exodus are unfounded. The market takeaway is one of heightened uncertainty, as business leaders and policymakers remain divided on the long-term impact of the city's tax strategy.
