We own several facilities, and if you want some general information there is the self storage association (SSA), and there is a publication called "inside self storage" and off course several trade shows. Different from car washing, self storage has a low entry barrier, and often there is excessive competition beating themselves up. It is difficult to justify a free standing facility that is not at least 40,000 sq. ft. or more. most new facilities are closer to 100,000 sq ft. Good luck
