You posted the same question yesterday. My response remains the same as then:
By whom do you expect to be paid ?
Landlords or Tenants ?
Remember, all Customers do not equate to Clients; just as all Tenants will NOT be Clients; nor will all Landlords be Clients.
Always know "who" you're representing, and "who" is going to cough up your Fee . . . . they may be different entities.
BTW, Do you have a Broker ?
