Sorry to chime in, but nosing around as I'm a "contemporary" of Beastman and have a son of same age and similar major.
Last summer, my son took two semesters of chemistry, a prerequisite for his materials class this year. He lived at home, but went to the local Catholic university. It cost me 6K for the summer. Thank God he has a full scholarship to his current school, but my goodness, that was almost Catholic high tuition for two classes. Not to mention my loss of income because of having to drive him to and from school, because buying him a car to use and insuring him to drive would have cost at least another 6K.
This summer, we are looking at sending him to his current OOS flagship and paying for the dorm, because we will probably BREAK EVEN! He's just finished his second year of mechanical engineering, came in with lots of AP for his gen ed, so only one course short of that, so really no local options for him to continue his education locally. (After Katrina, local colleges closed their engineering programs. Brilliant, right?)
My point is, suck up the rent if your kid can take a course on their "home" campus and actually can get a job on campus. I'm assuming your child has a car already, so that's not an added expense. If not, I'd consider staying on campus, especially if the job is on campus. Let him learn to love the rec center!
