I am a newbie and I don't currently have properties but having lived in college town for 4 years I know that the pros outweigh the cons. Many people are hesitant to invest in college towns due to high maintenance costs but there are just so many pros such as:
1) Rent payments on time - Parents usually cosign on the lease and students usually have loan money to cover cost for apartment even if they can't pay out of pocket.
2) College students don't complain much - I knew some people that literally lived in a crooked house for 3 years and each paid $300 in rent for a total of $900 for the owner. This house was pretty rundown and could not have been rented out otherwise.
3) Even though there is high turnover, the demand is super high so you are almost guaranteed tenants without little to no marketing. Ex: My brother lived in an apartment and decided to transfer out. He posted on his facebook college group that he was looking for someone to sublease his place for the remaining 6 months. Within 5 days, he had 6 people ready to take over the lease. Demand is very high and supply is usually low because colleges accept more and more students each year but housing options usually remain the same.
I am currently saving up to purchase primary property as well as invest in my college town. I think there is so much potential.
