Jeremy Lin, who famously slept on a teammate’s couch before he became a Knicks sensation, has found a fancy new apartment of his own in Houston. Sources tell us point guard Lin, who last week signed a three-year, $25 million deal with the Rockets, is moving into the city’s luxury Mosaic Building, which boasts a pool, full-service concierge and a spa. Rockets star Chandler Parsons also lives at the address. A rep for Lin didn’t get back to us last night.
