Strange Happenings In Tom Cruise's Building - 2012-07-13
My sources say Tom bought the place after doing Risky Business, so it has sentimental value for him and he'll never get rid of it, even if he's not really there a lot of the time. (And now Katie won't be there at all anymore.)
They also joke that since it's a rooftop duplex, it's easy access to the spaceship.
(It's a big Scientology building.)
