The key is accepting an offer of admission as soon as you are sure that you want to attend. My D accepted in February, we sent in the deposit, and did the housing contract. By the way, she doesn't know any current freshmen that have supplemental housing.
According to both of my kids who now attend PSU, a vast majority of the students who are in supplemental housing actually like it because the rooms are converted lounges that have a lot of space and they like having 5 or 6 instant friands. Some of the housing folks say they actually have a hard time convincing the supplemental housing students to move into a "normal" two person room when a space opens up. Also, room rates are cheaper.
My daughter was in a regular double and it honestly SUCKED~roommate was a spoiled, passive aggressive witch!
So what is the point of this post? Many, many university have supplemental housing. Who can afford to have rooms sit empty? All schools have students who don't show up or drop out early in the semester. Some Universities use the lounges like PSU others stick a third person in a double room, 3 girls - 2 closets, try telling me that is fun. Apply early, deal with deadlines, make the best of the situation you end up in.
Well said, though there have been years recently when PSU was so far off in their yield forecasting that, among other things, they tried to buy back the housing contracts of kids within commuting distance (without much success).
Grad students have a separate system and are not guaranteed housing. (PSU freshman are required to live on campus.) If a grad student wants PSU housing and it is full they have to find something off campus. There is probably a waiting list for on campus housing in the event that it is full.
