Earlier quoted context omitted.
Something about the savings math doesn't check out, especially given the NEET aspect. 200k savings in 4 years out of school is a lot.
$185k/48 = $3.85k in monthly costs saved by not living independently. I can see it as being possible in Seattle, but on the high end. I would assume comparable abodes to sharing your parents house would be cheaper. I also would not have wanted to stay with my parents in my 20s though, at least not with my specific parents.
I've known people who lived at home for a year or two to save money, but I wouldn't have been able to have any independence.
