What are the advantages of property companies compared with the same industry?

What are the advantages of industrial companies compared with the same industry? In fact, I think the development of urban property companies is becoming more and more mature, because the rules and regulations of property companies are very mature models. I think some advantages of property companies in the same industry are obvious, especially in residential areas. Their advantages in serving the owners are obvious and unconscious. Their service model is very mature, and they think that a good property management company can show a good service model.
