not til well into 20's.
HS, if you don't get on with your parents, then fine, but if you do, waiting a few years to move out will set you up financially much better in life and given that the cost of living everywhere continues to rise, it's a smart idea to wait.
So many of my friends moved out at 19, 20 etc in order to have 'independance'. Well, most are now 30 and none of them are very financially independant........they have very little savings to speak of and very little disposable income to enjoy and will probably never own their own their nown place. If you can't afford to live the lifestyle you want and deserve then independance means fuck all IMO.
