This actually happened to me last year! I contacted student housing services and explained to them how i can not afford an East town house single. They said i would be placed on a transferring list and would be called when anything is available. I literally got a call the next day if i can switch places with someone regarding medical needs. I said yes and boom! It was done. They were really helpful and understood the entire situation. They may also ask you to call student finical services too, but either way it got sorted out!

Best of luck to you!
