Tisch sells half of would-have-been Sarah Jessica Parker duplex

Laurie Tisch and unit 9N at the Brentmore

Heiress Laurie Tisch had very nearly unloaded her $21.5 million duplex at the Brentmore earlier this year, when would-be buyer Sarah Jessica Parker pulled out of the deal and took her Manolos to Greenwich Village instead. But that’s old news, and now so is the duplex, because Tisch just sold off nine rooms of it to a mystery buyer. According to a rep for listing brokers Cindy Kurtin and Jessica Vertullo Maher, both of Stribling & Associates, unit 9N at 88 Central Park West closed for $15 million. It wasn’t immediately clear whether unit 10W, the other piece of Tisch’s former 12-room spread, is still up for grabs. Tisch, the philanthropist and daughter of late Loews co-chairman Bob Tisch, originally listed the two apartments together for $25 million last August, after purchasing a $29 million spread at 834 Fifth Avenue in one of the biggest sales of 2009.
