Welcome! We also have a facebook page and we have all discussed housing options. Marquette sent all of us a housing guide, if you didn't get it call Marquette or search for it on their website. Most people seem to be looking into the "2040 lofts" or "Sovereign", they are two different apartment buildings. 2040 lofts has a website "www.2040lofts.com" and is rather expensive for Milwaukee. Sovereign is cheaper, like 35-40% less, but is a favorite among dental students so apartments might not be readily available.
I wouldn't stress out too much, you have plenty of time. I was stressing out looking for a place. After calling a few places I found out that it's still very early, most places told me I would be able to find several 1-bedrooms well into June.
