To buy an auction house, it is important to look at the five certificates, namely, the ownership certificate of state-owned land use right, the planning permit for construction land, the planning permit for construction projects, the construction permit and the pre-sale permit for commercial housing. These five certificates are dependent in the above order and are handled in turn. Now that the Internet is developed, the Housing Authority will release information in the local official website while issuing a pre-sale permit for a certain project. According to the serial number of the pre-sale permit, the user, scope and time of use of the pre-sale permit can be inquired from the public.
