I moved out when I was 18. Even with a job and stuff, it is difficult to do it on your own. My first apartment had 6 guys in it (honestly). That was probably one of the worst rooming situations of my life as well. Not to mention, I lent a guy around ~$1000 dollars and am still having it returned to me slowly. I actually recently signed a lease at a new apartment with 2 other guys. I am 20 now, so I expect this will be better all around. It's fun, but also a different lifestyle then living with parents to say the least.
