People or enterprises closely related to the property? What are the enterprises that know many properties in a city?

The person who knows the property company best must be the person in the housing management department or the property department of the construction department, and almost all the property companies in his jurisdiction know each other.

Speaking of people who know more about property in enterprises, generally speaking, the business personnel of energy sales companies such as water, electricity, heat and gas make the most friends with property companies.

There is also an advertising company salesman who undertakes residential advertisements, and they have more contact with the property.

As for developers, they don't know many property companies. Do you think small developers can develop several projects and have relations with several property companies? Moreover, large developers basically set up their own property companies, but also need to find others?
