Does the community management office need an agency fee to show people the rented house?

Yes, but only if you buy the house he showed you. Many people think this is right, but in fact you have already exchanged the goods.

In China, this kind of thing is often tipped. In other words, give the intermediary a little meaning at will. But in real law, you should pay the full agency fee stipulated by law.

Supplement: The property contract has nothing to do with outsiders. The property company itself has the service of hosting the house, and it is a paid service. There is a charge for service. In a sense, you have the right to choose a property company that can provide you with a house without your money, but you have no right to interfere in property management activities.
