Wow. It sounds like you have your mind made up to go to the out of state school. Hope it is Texas A&M?
Assuming this other state will be charging you out-of-state tuition rates, some people take off a year (or more) and actually move to and become a resident of that other state, thereby lowering the tuition. This would mean finding a place to live and getting a job. Any job that pays the bills - you just want to lower your tuition. It would be nice if it was someplace that actually offered tuition assistance. Again, the objective is to "use" them for their tuition assistance, it does not have to be your dream job. Another idea, rarely mentioned, is to join the military.
Beyond lowering the cost of school, you also want to look at the cost of books, as well as living expenses. There are a lot of options for books - rent, buy, new, used, etc. Become familiar with them and shop around. I buy my books, because I mark them up a lot. I find the best deals on-line. used.
Living expenses? The extreme: there was a guy who lived in his car while going to school. Got a gym membership, which covered the showering concerns. Stayed on campus most of the time, taking advantage of extended hours, etc. Found decent priced meals. Don't recall the school.
Take a hard look at transportation. Do you really really have to have a car to get around? Can a bicycle plus Uber during bad weather do the trick? Watch your meals. Find good second hand stores for clothes and dorm furnishings. And most importantly, learn to distinguish between wants and needs. Be super-frugal!
Utilize whatever you can get for "free" at school - believe me, you are paying for it! Entertainment, healthcare, photocopying/printing in the computer lab, etc.
When commuting back home, take the bus/train rather than fly.
I do believe that about covers it! Best of luck!
