Can a developer designate a property company to live in?

I can't. According to the relevant regulations, the state encourages construction units to select property service enterprises through bidding in accordance with the principle of separating real estate development from property management. At the same time, developers are not allowed to designate property companies. Therefore, the property company designated by the developer cannot go through the check-in formalities, and only the property company that has been legally tendered and legally settled can go through the check-in formalities.
