So we all remember the post where Apple is claiming its buildings are worth only $200 to avoid taxes?
All you have to do is craft a situation whereby you can sue Apple and win. Whatever it is, it would have to be something that they won't show up for or can't defend against. Maybe something where you sue for and win a couple thousand dollars.
When they don't show up or the lose the case, they of course won't pay you because they'll want to do everything they can to avoid that as long as they can.
There's where you move it into foreclosure as fast as you can. Each building only worth $200? TAKE. THEM. ALL.
You now own the entire Apple campus. Just start charging them a reasonable amount of rent. Enough for you to pay off your bills and live on, a little extra so you can invest (and enough to cover the real, honest taxes).
And if they won't play ball, evict them. Then turn around and sell the buildings for whatever price will make them sell nearly instantly.
