It depends. Right now, I'm 23 years old. I plan on living with my Mother until I'm at least 30 years old. I have no relationship with a female in my life. I'm not planning on getting married or having children so either. So at best, I live here until I'm at least 35 years old. That's 75-35 = 40. So for 40 years I'll have to subsist on getting by. If the inheritance comes out to 250,000 + 100,000. The house for example, costs $250,000 dollars. Then I would be left with 100,000 left over plus the money earned from SSI. Figure it costs 10,000 a year at best. Then it would only last me 40 years. With 38,000$ left over. Figure in the factors of slightly increasing SSI, slightly decreasing the workload (as it becomes more automated), and the advancement of tech. So I would be obviously penny piching but getting by someway in one way or another.

This ($38,000) also does not factor in the next 5 years of my parent's salary + my father's inheritance that he hands down to me. This means that I'd be looking at an additional $100,000 + $150,000 or more, depending on how financially responsible my parents are during the next coming years with their retirement as well as how generous they are to me. This also doesn't include my work employment future, which I don't plan on taking hold as I am working on automating creative design and implementing the algorithms necessary for the digital cycles.
