How to tell whether 58 city rental information is an intermediary, an individual or a liar?

I can only distinguish the first two. The third depends on the specific situation. If the first one is an intermediary, you should ask him if there is anything else besides this house. You'd better help me find two sets. If it is an intermediary, I will usually answer you immediately where there is another set or I will help you look at it. If it is the landlord, it is generally very direct and there will be no procrastination. Unless it includes tenants.
