No, this is Ira Rennert's house in Sagaponack, New York. Took me a bit to figure this one out. Property taxes for Bernie's Long Island house were listed at $17,000 in one article so his digs are much more modest in comparison. This house has taxes of approximately 400k per year which values it at 170M.
