When I was in school I could live off campus (3 miles away) and eat at restaurants for 2/3 the cost of the dorms. Since I cooked my own food I saved more. Your daughter might try that after her first year.
And cooking for one can be uneconomical. Now, if she shares a house with some like-minded girls, it could work. But I think freshmen and maybe sophomores are required to live on campus.
