For many young people, moving out of their parent's home is a huge milestone. Some want to move as soon as they turn 18, but others prefer to take their time.
However, money is no joke. So, the most important question you should ask yourself before you begin apartment hunting is “can I afford to move out?” Do you have a steady income? Can you stick to a budget? Do you have reliable transportation? These are questions you need to answer honestly before you should even consider moving out. Having your own place seems like fun because it means freedom, but there is nothing fun about not being able to afford rent on a lease you've already signed. Living on your own comes with freedom, but it also means a lot of new responsbilities.
Asking yourself difficult questions is a necessary part of being an adult, and if you can do that and think about your answers honestly, you're a lot further along than you think. Being responsible is one thing though, and having the finances to live on your own is another topic. If you need another year or two to save up money, although it may not be exactly what you want, it will be the responsible thing to do for yourself!
