The guy's a billionaire and he's taking a mortgage?

Shhhh! He's causing more fiat to be printed thereby increasing our Bitcoin value. Don't tell him about the compound interest!
It is cheaper to take a mortage than paying the full price directly, even for a billionaire

He's actually doing what a true believer should do. It means he doesn't need to sell (or, indeed is able to buy another) 250 or so coins in this case, while putting up the coins in collateral.
He probably has to put up double or so to mitigate against the market going down, but still, he gets to buy the house and still enjoy the moonshot which he clearly thinks is on the cards.
Its good to make the coins work for you, though there is de-anonimisation and counterparty/seizure risk of course.
Not only that. The property is also collateral... Plus all his net worth... present and future income. It's all just a publicity stunt. A good one though.
