If someone looks at the house, does the agent need to call the owner?

Yes, first of all, the intermediary must call the landlord to explain the specific purpose, and must first understand each other's ideas and see how the other party plans the house. If the other party does not have a strong intention to cooperate, then the intermediary can't force it, and it is very easy to resent forcing others. Secondly, when the intermediary calls the landlord, it is also necessary to clarify the corresponding services, which can also attract others. Now many houses are directly in intermediary companies. Of course, it is definitely beneficial to the landlord to hang the house in the name of the intermediary company.
