1) Case and Emory have a lot of clinical sites to choose from. The Houston location is attached to the Texas Medical Center, so there will never be a worry about getting the best sites. Emory has a class size of 36 and a lot of hospitals to choose from in the downtown area. So I don't think there will be any problem with getting the best sites for either program. I can't tell you about Nova because they wont even tell you their clinical rotation sites and trust me, I tried to find out during the interview and they still wouldn't budge on locations. The first year students that were in their fall semester didn't even know where their rotations were yet for the spring.
2)Emory has a really nice, modern classroom and a very nice simulation lab (One sim lab). They also have a didactic area where you can practice on mannequins I believe. Nova has really nice simulation labs that look brand new and top of the line (two sim labs). The classroom at Ft Lauderdale is also extremely big. CWRU has very nice sim lab just like the rest and the classroom is being moved to a new location at Houston so I can't say anything on that but the one I saw was very well maintained.
3) CWRU Houston is really cheap to live around because its Texas. The Dc location will be expensive to live at, and I didn't do much research on the Cleveland location. Emory and Nova are pretty expensive to live around but you can always split the cost with people in the program.
4) CWRU Houston has employers higher all around the area but CWRU allows you to set up a clinical rotation site of your choice just like Emory and I think Nova, so don't worry so much about jobs in the area. Just try to be flexible and go where the jobs are.
