[X-Men] Where does the money to run/pay for Xavier's school/mansion come from?

Is it profits from business? Investments? Tuition/rent? Family money? Does he hire out X-Men/Women as mercenaries or bodyguards?

His family was old money wealthy for generations, and on top of that a lot of the school's equipment was either acquired from his time in space among the Shi'ar, or produced directly by mutants who joined later, like Forge. And of course, he's not the only wealthy mutant or benefactor contributing to the school, Warren Worthington (Angel) also contributes money to the school for instance.
