I am a fourth year at UHS and I will tell you that most of my friends live somewhere North of the river. North of the river has some nice neighborhoods and great schools if you have kids. It is also much more affordable than living in other parts of the metro (esp. Kansas). The commute has never been a problem for me. I typically beat the morning rush in to school (good study time) and school nearly always lets out before traffic gets too heavy. I live in Gladstone, eight miles north of the school, and can easily get to and from UHS in 10-12 minutes. Liberty is a nice suburb with great school and easy access to a couple of the hospitals that most of you staying in KC will work at. It is true that there are affordable places to live around the school and downtown but I'm not sure how safe they are. Most people will tell you they haven't had any probs but I know a couple of my classmates that did have problems around the school. Brookside is a nice neighborhood. If you have a little money to spend and want to buy...Johnson County, Kansas and Lee's Summitt, MO are also good choices, but the travel time can be bad.
I've seen a couple of posts that suggest there is going to be construction on the main bridge (Paseo bridge over MO river on I-35) next year, but as far as I know that is just rumor. The bridge was actually repaved about a year ago. Nevertheless, there are several other good ways to get to UHS from the Northland.
