Actual room and board costs for years 2-4

If anyone here is familiar with the co-op program at Bama, can they please elaborate on the housing? Where would students who participate in co-op live? And is the housing (and transportation) be provided by the company? If not, is the pay good enough to cover all the costs for that period and still have some left? Finally, when exactly does this co-op happen and for how long? Summers or in between the academic year? One term of four months or three such terms?
As an international student, I want to graduate debt-free while still having the possibility of getting a job after graduation (not easy for internationals). But I digress. My main concern is the living costs during co-op.
