I recently moved to Tucson as well. My wife and I moved to the west side, in the area of Sweetwater and Silverbell (about 1 mile west of I-10). This provides an "out-of-the-city" feel but also allows the convenience of having a relatively straight shot into town. The drive takes less than 20 minutes, I would guess, to get to UMC. I agree with the previous poster regarding a 3 month apartment lease. Unless you know an area of town you would like to live, and you have an idea where you will be working, the interim time will give you a chance to get a handle on this town and figure things out.
