1, the transaction is unfair. Under the auction sales system implemented in China, the house is still under construction, and the buyers pay all the house price and bear all the risks in the future. When the completed existing home is inconsistent with the agreement, advertisement and verbal commitment, it is often the weak buyers who are forced to accept the housing that does not meet the demand or bear the liability for breach of contract. This is actually in the name of auction sales, to achieve the essence of existing home sales, and to pass on the business risks to the society.

2. The sales are not standardized. Housing is a non-standardized product. Because of the different location and space, the quality of each suite source is different.

3, resulting in unequal competition and inefficient competition. The auction sales system lowers the threshold of the real estate industry, and the strength, brand, technology and strategy of developers are not very important. As long as they have the ability to balance the powerful people of local governments and commercial banks, they can get cheap land resources and low-cost bank loans, which means the success of the project.

4. The legal system of pre-sale of commercial housing in China is not perfect. Ten years ago, China promulgated and implemented the People's Republic of China (PRC) Urban Real Estate Management Law, the Urban Commercial Housing Pre-sale Management Measures, the Commercial Housing Sales Management Measures and the Urban Real Estate Open Management Regulations. However, as the legal system of pre-sale of commercial housing and its standardized market management, there are obviously many defects.

What does the pre-sale system of commercial housing mean?

Pre-sale of commercial housing refers to the behavior of real estate development enterprises to sell the houses under construction to the winning bidder in advance, and the winning bidder pays the deposit or house payment in advance. Specifically, it is customary to call the houses under construction, unfinished, undeliverable, and without property right certificates as faster houses. Developers selling faster houses are called pre-sale, and buyers must sign pre-sale contracts with developers when buying a house. This system is the pre-sale system of commercial housing.

Pre-sale of commercial housing, also known as house pre-sale and uncompleted residential flats pre-sale, refers to the real estate transaction behavior that the real estate development enterprise and the purchaser agree that the purchaser will pay the deposit or advance payment at a certain date in the future and own the existing house. Its essence is the buying and selling of housing futures, which is just a futures contract of housing. It and existing home sales have become two main forms of housing sales in China commercial housing market.
