I still think kerrytown is your best bet. Close to the dental school and also close to main street bars/restaurants. I would say find a roommate to cut the costs. If you do look at places on north campus, just keep in mind the 10-15 minute bus ride you will take two times a day with all the undergrads. Or I guess you could drive but I don't know if there are places to park around the dental school. If there is a big cost different and it seems worth it to you, then go for it. Also, I went to umich for undergrad, not dental school, so take this advice with a grain of salt and talk to some current students to see where they live.
