Need An Apartment In Studio City?

There are a number of available apartments in our building.  One of my favorite hobbies is exploring them.  They have "Open House" signs posted on them so I figure I'm allowed to enter at any time I choose.  I'm not sure what I'm going to do when someone actually moves into them.  I'm starting to feel attached, as if they're mine.  This one in particular has a fantastic view of the hills and the pool.  There are days I'd like to pack up my belongings and move into it.  Couldn't I use it as an office or something?
