Question

The Campus Housing Service helps students find apartments. Owners of apartments fill in information forms about the rental units they have available (e.g., location, number of bedrooms, monthly rent). Students who register with the service can search the rental information to find apartments that meet their needs (e.g., a two-bedroom apartment for $800 or less per month within 1/2 mile of campus). They then contact the apartment owners directly to see the apartment and, possibly, rent it. Apartment owners call the service to delete their listing when they have rented their apartment(s).
