Pakistani land records show that Osama bin Laden paid $1 million for his compound—but that was in 2005, before the real-estate bubble popped. As-is, the compound is now worth probably $250,000, and cleanup costs from a Navy SEAL raid are separate and considerable. Assume that OBL put $200,000 down. So he has an $800,000 mortgage on a property worth only about a third of that.
Yes, you guessed it: Osama bin Laden is going to be underwater for a long time.
