Who owns the property right of the sales office?

Legal analysis: it depends on the specific situation: who will manage it and see the ownership of property rights. If the developer does not sell, its ownership belongs to the developer, who decides to manage it by himself or entrusts the property company to manage it. The sales office belongs to all owners (included in the owner's house price) and belongs to the property management company entrusted by the owner.

Legal basis: Article 61 of the Law of People's Republic of China (PRC) on Urban Real Estate Management shall apply to the land administration department of the local people's government at or above the county level for registration, and the land administration department of the local people's government at or above the county level shall issue a land use right certificate after verification. If a house is built on the land for real estate development obtained according to law, it shall apply to the real estate management department of the local people's government at or above the county level for registration with the certificate of land use right, and the real estate management department of the local people's government at or above the county level shall verify and issue the certificate of ownership of the house.
