Been a landlord for 6+ years and never had to deal with someone this immature. 

I think we've all been there to some degree in our immaturity and especially in  our youth, simply lacking wisdom of how predators in the jungle seek and snag their prey.  

College students present a higher risk because they are immature and lack experience with finances.

That's an extremely immature statement to make lol I'm glad you're in Evergreen, CO too because I love doing deals there.

It's immature to perpetuate an "us vs. them" mentality.

They were immature and very unprofessional. 

I haven't had any negative experiences with that group of immature racist complainers. 

I plan on harvesting part of a lower-quality 86-acre parcel in Hallsboro NC and some smaller (35ish) immature parcels scattered about in NC.

Large semester gaps and young immature students with barely any rental history or life experience can damage your place and skip out on a judgment just as well as any Section 8 tenant (in fact, in Pittsburgh, people who owe on a judgment can't be on Sec 8).
