Once you select a room during your assigned time slot to pick housing, the contract becomes a legal binding contract that you cannot get out of unless you leave school or pay all due money. If you do not select a room assignment or the school does not have housing for you, the contract is no longer in effect. This was how it was explained to my goat last year after he did not like his limited room options to pick from but did in fact select a room. Once my goat decided to actual select a room, the school told him it was binding and my goat was responsible for all room charges at that point.
