<p>I do commercial real estate financing, and I can tell you that student housing markets are generally either 12 month markets or 9-10 month (school year) markets - rarely is there a mix. Usually if you have a 9 month lease you’re paying a premium anyway. Frankly, it’s nice to have a place to store stuff during the summer, and it’s often possible to sublet (although that opens up its own can of worms).</p>
