But try it in a non-university town where non-students vastly outnumber the students? I don't think so. The landlord has everything to risk and nothing to gain by doing strange and unfamiliar things. If they have even heard of the practice, it's only for students, in student-dense areas, in housing long used in this way, with all the features (internal locks for each room, etc.). Why would they risk their nice house when they can just rent to somebody else?
