Off campus housing?

Can anyone comment about what off campus housing options are like for students? Do most upper classmen live off campus?

Based on the experience of my D and her friends, it seems that most students (excluding commuters) live in Dorms the first 2 years. However they may move to a different Dorm in Sophomore year, and some do choose to live in apartments off campus, such as the Varsity or the View. For Junior and Senior years, most move to apartments.
