The 4,825-square-foot Time Warner Center penthouse once rented by Jay-Z has gone into contract for $31 million, according to the Post. At over $6,400 per square foot, the deal would be the priciest ever at the Related Companies-developed condominium tower. The 76th-floor spread has tried for building records before; in 2010, current owner Todd Wagner, Mark Cuban’s co-founder of Broadcast.com, put it on the market with the penthouse upstairs as a potential $73.5 million combination — the most expensive listing in Manhattan. On its own, Wagner’s apartment, which he bought from investor Michael Hirtenstein for $27 million in 2007, was last asking $38 million. [more]

The 76th-floor Time Warner Center penthouse that Jay-Z once rented for $40,000 per month is back on the market for $38 million with Prudential Douglas Elliman’s Raphel and Claudine De Niro. That’s $11 million more than what it sold for in 2007, when Todd Wagner, the dot-com era business partner of Dallas Mavericks owner Mark Cuban, purchased the four-bedroom, five-and-a-half-bathroom apartment for $27 million, or $5,596 per square foot, from telecom entrepreneur and real estate investor Michael Hirtenstein. Hirtenstein had bought it for $15.7 million but later had second thoughts about moving his 10-year-old daughter into the place. He rented the penthouse to Jay-Z instead before selling it to Wagner in what was, at the time, the highest price-per-square-foot ever paid for a Manhattan condo. [Curbed] 

An Asian financier calling himself “J. Lo” is reportedly looking to buy up luxe apartments in Manhattan’s premier buildings with haste. Lo, who is currently renting a $100,000-per-month condo at West 56th Street’s Park Imperial, counting neighbors like Daniel Craig, Sean “Diddy” Combs and Deepak Chopra, also recently signed a contract at the Park Laurel on West 63rd Street. He is reported to have paid nearly $28 million for the 7,758-square-foot spot that belonged to Israeli philanthropist Ephraim Gildor. Lo hasn’t made an offer yet on the $31 million penthouse he visited at Trump Park Avenue, but he did bid almost $40 million on Broadcast.com founder Todd Wagner’s apartment at the Time Warner Center, which, unfortunately for Lo, isn’t actually for sale. Wagner bought the 4,800-square-foot penthouse, once famously rented by Jay-Z, from real estate investor Michael Hirtenstein in 2007. Observers have noticed Lo’s black Cadillac Escalades idling outside his current rental, where he’s had shopping bags from Bergdorf Goodman delivered to his door. [Post, 1st item]
