Why should the key to buying a house be collected in the property?

Of course, you have to take it to the property. The developer informs you to hand over the house, indicating that the community has reached the delivery standard and can be delivered for use. The developer is in the early stage of the project, and the property is responsible for the later service. The turnkey project should be the responsibility of the hotel. You want developers to do it, but people don't want to do it. Moreover, when handing over the house, we have to sign a property service agreement and begin to formally become the owner of the community.
