[SERIOUS] How tf a law professor has $250MM+ in real estate?

OK, we've seen the massive amount the bail was charged at. The big elephant in the room for me is: just how? How is it possible that a professor of Law has $250MM in spare real estate? I say spare because both of suckerboy's parents willingly paid his bail and still have a Palo Alto mansion worth $3MM+ to live.

The average salary of a Law professor in USA is around $180k:

Alright, let's say they are the really good ones and are in the top, earning circa $250k a year. That makes half a million a year, which means they'd have to work for 500 years just to have the money for the bail, not considering taxes.

Joseph, the father, supported Elizabeth Warren in 2016 in the Tax Filing Simplification Act and worked 11 months in FTX doing "charitable work". Barbara, the mother, co-founded the Mind The Gap fundraising organization, which is meant to support the Democratic Party. She also has a law degree. Both taught at Stanford.

We don't know yet how much Joseph was paid during his FTX times, but honestly I tend to believe it was enough to bail his kin. I'd not be surprised if the bail, if the money is chased to the beginning of the process of buying millions in real estate, was paid with customer funds.

EDIT: thanks for the answers and clarification on the matter! Now I know how bail in the US works. TL;DR: they gave the home as an IOU-like thing, which is priced as a few % of the bail, as a collateral for SBF not to flee.
