Utilities depend on the apartment complex. Some are included, some only include some, and some are separate. For houses it's generally separate. Utilities are pretty cheap here, though. There's no place that's really bad enough that I'd say to avoid, it just depends on how much noise or how long of a commute you can tolerate. As far as I know, grad students are mixed up with the undergrads unless they have families, then they tend to live in some of the newer, bigger apartments farther away from campus. Graduate students here tend to live in studio apartments more, though. I'd say try Facebook, kentwired.com (the school paper's classified), kentapartments.com (management company) and Craigslist for listings.
