Don’t say we didn’t warn you: “Tax the rich” always moves past “the rich” real fast. It’s happening with Gov. Kathy Hochul and Mayor Zohran Mamdani’s new pied-à-terre tax before they’ve even figured out how to make it work (if they even can). They announced it as a surtax on 13,000 uber-wealthy nonresident NYC owners of second homes worth $5 million or more. Weeks later, Hochul’s office on Thursday suddenly “explained” that this actually means it could hit condos and co-ops with assessed values
