You should at minimum listen and consider what your parents' advice is regarding your choice in university. There are many factors to take into account that one may not think about having lived at home 100% of the time. If your parents are paying for some or all of your college, then that would give them the advantage in the decision of where you go. If they are willing to pay for in-state schools, but your choice is an out of state - there are definite extra financial burdens to commit to. Also, depending on how your personality/relationship is with your family, the further away from home you are, the more on your own you would be if you find you need assistance.
There's also the consideration of whether or not you'll get into your school of choice - maybe you will, maybe you won't which will make the point moot. Most applications will cost money too - some schools offer cheaper application fees than others.
Things they are probably considering is the cost of tuition/books, room/board (are you going to live in the dorms or in an apartment - if the later, then how are you going to get groceries, pots, pans, etc...), items you need to live away from home (clothes, bath towels and other accessories, computer, furniture, cooking supplies or dishes, etc...), transportation (will you need a bike, scooter, car...will you need to drive or take the bus to get home), will you get a job or study full time, extra expenses like tickets to school games or movies or eating out..., phone bill charges, etc...
Often when one is still living at home, you don't fully realize how much it costs to live on your own until you start receiving the bills. There are those that pass them off to their parents to pay, not taking any responsibility for their spending habits; then there are those that gain wisdom and understanding about how to budget.
The advice from others about considering longer term goals is a valuable tip too - do you need a full university degree now, or based on your financial status, would it be better to get some breadth courses completed at a local tech college that can be later transferred to a college when pursuing your degree. Doing that could help save up for the university studies by working while attending school to save up for the full university costs. Others mentioned online courses (which can also be transferred).
When I graduated, it took me 8 years to pay off the debts I accumulated while in college, and my parents helped pay for some of my schooling (they paid room/board, I paid tuition - when I moved out of the dorms, they gave me a monthly stipend I had to budget for paying rent, food and utilities). You could get student loans, but how much in loans will you have by the time you expect to graduate...how long will it take to pay that amount off when you are on your own - paying rent, food, utilities, transportation, insurance, etc..plus paying off the loans.
Good luck in your decision!
