Living on campus as an underclassman is difficult for a one major reason. They give you the worst dorms on the whole campus. There will almost never be A/C, and there will usually be an abundance of asbestos (At UMass Lowell, we couldn't even touch the ceilings in the freshman dorm because of this problem). I will say though, that I moved off campus after freshman year, and by senior year, I was regretting not still living on campus. The biggest advantages to living on campus are that campus is where all the fun is, and the commute basically involves rolling out of bed. I say wait a year at least, and then try and get housing after that. That way you're more likely to know people to room with, and you'll be eligible for the better facilities (If you can get enough friends together, suites often have their own bathrooms!)
