Quote from @Todd Goedeke: @Jon Martin You are right , if you don t know how to market a property and get direct reservations you should not attempt to co-host or triple net lease a property.You fail to mention that leases on a property can be as long as 30 years.Long leases are a way to give both property owners and management companies favorable terMs.How common are 30 year leases for SFRs?
