Milk that situation for as long as you can and SAVE as much as possible for as long as possible and whatever you do, don't touch that. Let's say you save 500.00/month until you reach the age of 21..... that's 18,000.00. Add tax returns and you'll be looking at an account balance of roughly 21,000-22,000. Before you have to move out and get your own, make sure you have some very low risk, high reward income streams using no more of 10% of your balance. If you have a good revenue stream and you're adding money to your account, then reduce the amount of money you put into new investments every year by 1% until you reach 1%. If you play your cards rights, you should have at least 100K(this is low-balling)by the time you reach 30, especially if you are living within your means or even under.
