Separated couple Elie and Rory Tahari have a signed contract on their downtown triplex at 141 Prince St. for north of $25 million, reports The Post’s Jennifer Gould Keil. That’s more than the unofficial asking price of $22 million and a big deal for downtown real estate. There was even a bidding war — but at the 11th hour, a hedge fund bachelor was outbid by the mystery buyer. Although the deal is expected to close soon, a rep for the Taharis still denies the apartment was for sale, let alone sold.
