This, really, really this. When I've searched for apartments in the past, one of my primary concerns has been ensuring that the apartment management is ok with my reptiles. I have *never* had a problem once I've made it clear that they're not free roaming and don't generate any odors. Also, apartments, at least in my experience, tend to be cheaper than living in the dorms anyway (presuming a reasonable number of roommates to split the rent cost), so it's a double benefit.
On a separate note, I think we need a sticky "don't try to smuggle your reptiles into housing that prohibits them" thread, as this subject comes up on a pretty regular basis.
