If you drive, check out the traffic around your potential location, especially during rush hours.

I live about ten miles from my job and have a 20-minute commute. I've realized since moving in that I could have lived several miles closer, but then instead of taking the interstate I would have had to take the state highway, and the 5 pm traffic is so bad on that that my commute would be more like 30 minutes.
