How old are your parents? The general rule of thumb is that you need to save 8- or 10-12x your annual income for retirement. If they are anywhere near retirement age they honestly probably couldn’t afford to pay for your college. We don’t know the details of how they blew through that money (they may have moved it to another broker) but even if they still have 600K that could be their entire retirement savings. You can go through that quickly with a major health issue. If you look on the bright side it’s nice that you can always stay with them when you fall on hard times…
