The "two books" can be used as a supplementary agreement to the commercial housing sales contract, and are legal documents and guarantee documents provided by real estate development enterprises to the buyers when the commercial housing is delivered for use.
five certificates of real estate and their respective legal functions
"five certificates" refer to: the first one is the state-owned land use certificate. China's "Land Management Law" stipulates that land belongs to the state or collective, and only the state-owned land use right can be transferred, and the collective land use right can only be transferred if it becomes the state-owned land use right through expropriation. Only houses built on state-owned land can be sold. If you can't get the right to use state-owned land, you can't get the real estate license, and the house can't be transferred, mortgaged and rented normally. In order to obtain the right to use state-owned land, it is necessary to pay the land transfer fee to the state, and developers are often unable to obtain the land use certificate due to various reasons such as lack of funds and tension;
the second is the construction land planning permit. According to China's "Land Management Law", construction land should conform to the state's overall land use planning;
the third is the construction project planning permit. Where the house is built, how high it is to be built, and what the floor area ratio is, it must be approved by the planning department;
the fourth one is the construction permit. Only with this certificate can the project be constructed;
the fifth is the sales license (pre-sale license). Without this certificate, the house can't be sold or pre-sold. Generally speaking, if the developer doesn't have the first four certificates, he can't get this certificate. But you can't just look at this card without looking at the other four cards in order to save trouble. Property buyers should check the five certificates together to ensure foolproof.
