Dorm to University Apartment

So I kind of last minute decided I would rather be in an university apartment than a dorm. I submitted the CAR asking to swap to 2bd/3p (single). I am wondering the likelihood of this happening or like being able to switch from the dorms to an university apartment in general. Are there university apartments that are you easier to get into? If so, can I resubmit my CAR requesting to get into these apartments. I would really prefer to get a single room if possible.
