Incoming 2017 had around 6,800 students and there were reports of triples and some lounges being converted to rooms (4 students to a room). 2018 was approx. 6,200 and it didn’t sound like there were any triples or conversions. Their target for 2019 was 6,600, but by the sound of it they may have exceeded that (and possibly exceeded 6,800 from 2017).
There’s construction underway for a new residence hall near the bookstore I believe. But it would have to move at breakneck speed to be done by August.
This is just personal opinion, but even if it meant sharing a triple I think I would want my student to live on campus just because that experience is worth it in their first year. But, if you are going t consider off campus you should start looking right now. Several complexes filled up as early as November.
