You are asking for a full-service property manager for your short-term rental. The management fee is whatever you and the property manager decide. Typically, it runs between 20-45% of rental revenue, depending on the level of support provided. For instance, some property managers can provide daily maid service and full concierge support, which would put you at the higher end of that range. The property manager typically arranges the cleaner, maintenance, and any repairs needed, but these are typically additional costs above and beyond the management fee..
There are also property managers that will do partial management, with the services split between manager and host. For instance, you could set it up so you take care of the money, bookings and all guest communications, and the property manager provides the rest of the services. That typically runs anywhere from 10 to 15% of rental revenue, depending on agreement.
