“Property management services” are programs provided by private companies for a fee, which help an employee to manage his/her residence at the old official station as a rental property. These services typically include, but are not limited to, obtaining a tenant, negotiating the lease, inspecting the property regularly, managing repairs and maintenance, enforcing lease terms, collecting the rent, paying the mortgage and other carrying expenses from rental proceeds and/or funds of the employee, and accounting for the transactions and providing periodic reports to the employee.
