it just makes me think "again" that Michael never actually lived at carolwood and that he always was in Vegas. Even his kids, back in 2009/2010 said they remembered good time with their dad, eating skittles, watching Vegas town from the house's roof. And we have Taj visiting him in Vegas at the moment where he should have been in Carolwood "maybe"
I know i have no proof, but my feeling is that this house in carolwood was not one where Michael would like to be. I can't imagine him to choose this house.
