I'm not going to judge the guy, but by his own admission, he only saves $33K over the course of 4 years doing this. Even if we assume that's after tax savings and he'd have to make $48K (guesstimate) in gross salary, that means he's only "saving" $12K a year doing this. On one hand I think the invonvenience of living in a van is not worth saving $12K a year, especially if he only has 22K in student loans while making $100K+ a year in salary. On the other hand he also says that he wakes up at 5:30 and works on personal projects after work until 8-9pm so he really doesn't need an apartment, just a comfortable bed to sleep at night, and paying $1K just to sleep at night does seem kind of steep. My line of thinking it's his life, he can do with it whatever he wants as long as it doesn't cause problems for anyone else which it seems like it doesn't.
