What do I include with my college student rental applications?

[Ben Freiermuth]

Hello! I am a soon-to-be rental property manager for my father's college rental business located in Whitewater, WI. We have 85 units in our portfolio. We recently purchased Buildium for our property management software, and the software includes a rental application that I can customize which fields to include/exclude. Currently, we require basic contact info of the applicant, a drivers license, and an emergency contact (parent). We have not run any background checks on college students since they have no credit history, but the software allows us to run checks on them if we wanted to on our higher end units. 

My question is, what information have you found useful for renting to college students? Any recommendations to background checks/co-signing parents, etc.? Thanks!
