Question for people who went through the Vacancy Application for living on-res

I missed out on the 100% first year guarantee for living on res so I got put on the Vacancy list.

For people who had to go through the vacancy application in the past, what were the chances of getting an offer back? And if you did, was it your preferred choice etc.

Asking because I do want to live in residence but I don’t know the chances of if I actually get in. Just want to know if there’s a good chance or I should start to find someplace to live off-campus ASAP.
