I've moved 3 times to attend universities, getting farther away from home each time (undergrad one state away, MA and now PhD halfway across the country).
Scholarships and financial aid packages are important, it takes a bit of research, but you can figure out the costs of things like housing and meal plans at the university fairly easily. There are often on-campus job opportunities too.
Depending how far you go, or what your/your family's income looks like, visits home over holidays and breaks are easy ways to stay connected. And sometimes university housing over the summer can be expensive, so it's kinda like a vacation to go home or back to school if you're in dorms during the semester and not renting a place for a full year.
I'd think about what weather you prefer (some people don't like harsh winters or hot weather, even the kinds of natural disasters that impact a place might be important to think about).
I feel like so many people in college are "starting over," at least at the schools I've been to, so you'll hopefully be able to find community in that.
I hope any of that was helpful, I'm happy to say more if you have any specific questions!
