Under what circumstances can a property company with corresponding qualifications be hired by agreement?

Early property enterprises were generally subordinate enterprises of developers. "Property Management Regulations" clearly stipulates that the construction unit of residential property should select property management enterprises with corresponding qualifications through bidding; If the number of bidders is less than three or the residential scale is relatively small, with the approval of the real estate administrative department of the district or county people's government where the property is located, a property management enterprise with corresponding qualifications may be selected by agreement. This regulation has curbed the nepotism between property management companies and developers to a certain extent.
