I don't live in res on campus here, because I live with my fiance, and I'm not sure res allows couples to cohabit...and then I have pets and a lot of stuff that wouldn't fit in a small apartment type setting (this is my second go at college after about 5 years of living with my fiance). Even so I wouldn't live in res here since they don't allow single serving bottled alcohol because people might break the bottles and hurt each-other.
Also consider renting a townhouse between 3-4 people that you can trust, the first place I lived in was with my fiance (then girlfriend) and two other classmates. Which divided the total rent of the place from 1200 Canadian dollars, down to 300 each, very affordable for fairly decent housing, privacy and space/backyard to party.
I'm not sure what the cost of residence is but I'm sure it's much better than my 800 per month rent for the duplex half I'm renting now.
The short note of living outside of your parents house, is don't leave because it's free food and housing with people you love, if you have to leave for any reason be aware of whom you are living with and what sort of housing you are getting for the money. Do not rush this decision if you have the time to shop around a bit.
