Mm.. apartment is a waste of money though. There's really no reason for him to live on his own besides social norms (Which I doubt he cares about). It's a complete waste of money unless the people you live with don't like you living with them. That's some financial stupidity really... You move into a shittier place with no stuff, have to pay bills that you wouldn't otherwise pay(or pay as much of), and for what? "To be on your own..." What a joke.
I'd move into an apartment if it wasn't too prohibitively expensive, there was a job/school I wanted there, and was in a location I'd like. Otherwise... why bother if you can live somewhere else that's just as nice, if not better, for much cheaper? Financially... it's irresponsible to go renting an apartment. Money into the shitter. That doesn't get you any return in investment at all.
