You will have to communicate with the person you are using as the agent to determine the details of when payments will be given to you. This is because it is a contractual matter between you as the landlord, and the person you are using as the agent for the landlord, when dealing with the tenant. The Residential Tenancies Act only deals with matters that arise between a landlord and a tenant; it does not get into any details about how agency contracts work.
