• Albert Hammond Jr.'s East Village apartment has gone back on the market. Hammond originally listed the two-bedroom pad at 141 East 3rd Street for $1.199 million last August, and went into contract to sell it before the buyer dropped out. He later re-listed it for $999,000, but then took it off the market altogether in January. It's now back—and cheaper than ever. Hammond's apartment can be yours for $899,000. [Cityfile, Corcoran]
• Warhol muse Jane Holzer has finally closed on the sale of her apartment at 23 East 74th Street. The five-bedroom home, which hit the market last June for $22.5 million, had been reduced to $16.9 million by the time it went into contract in March. The deal has now closed: Apparel mogul Jason Rabin and his wife Nicole picked up the apartment for $14.1 million. [Cityfile]
