The duties of a residential property manager are to maintain and improve a residential investment property and to provide the tenants with necessary maintenance services, such as conducting simple repairs or making improvements to the units. Your responsibilities to the owner of the building include marketing the property, such as placing ads or holding open houses, screening applications, and handling payment and eviction issues. You need to be able to draw up the rental and lease agreements, keep proper financial and legal documentation related to the building, and ensure that the building complies with all local, state, and federal building and safety codes.
