I have never been a college landlord, but I have been a college tenant. The first thing that semi confuses me about this post is that people keep talking about "9 month leases". Is that how it is now? I went to Liberty University in Lynchburg VA, and Radford University in Radford VA and I always rented for the entire year (as did everyone else I knew). I've actually never heard of anyone only renting for 9 months unless it was a SPONSORED campus housing. I don't know why anyone would ever even offer that. Kids typically like the year long leases because they don't have to pack up all of their stuff and vacate the dorms at a certain time.
Being as though I was recently a college student I feel like a 9 month lease (with turnovers) would be an absolute nightmare. I will say, as long as student loans exist, there is a huge market for college rentals. I went to both private, and public institutions and I saw how common it is for students to pay their rent with portions of their student loans. In fact, a former roommate of mine paid 6 months in advance.
I'm a big proponent of college rentals. Most of you are going to disagree with me on this one but especially to Sororities (and sometimes Fraternity's).
