Between my wife and I, maybe 4.
Disclaimers:
1. I wouldn’t necessarily feel the most comfortable asking for that type of money from anyone, even my parents.
2. Some of these people may not have it liquid but I’m sure they have accounts (investment/retirement) that have much more than that
3. I’m not sure they’d all say yes to that amount of money
4. All of these people are family. I don’t have any friends that have that much money sitting around. At least not that I know of, and I don’t talk to my friends that deeply about their financial situations… and I don’t care to.
