Real estate is a comprehensive and complicated concept. Physically, it is composed of buildings and land. Land can be divided into undeveloped land and developed land. Buildings are attached to and combined with the land. Building refers to the product of artificial construction, including houses and structures. [ 1]
The concept of real estate should be understood from two aspects: real estate is not only an objective material form, but also a legal right. As an objective material form, real estate refers to real estate and real estate, including land and permanent buildings on land and their derived rights. Real estate refers to all kinds of houses built on land, including residential shops, factories, warehouses and office buildings. Real estate refers to land and certain space above and below it, including all kinds of underground infrastructure and ground roads. Real estate is also called real estate in economics because of its own characteristics, that is, the fixed position and immovability. There can be three forms of existence: the integration of land, buildings and houses. In the auction of real estate, the auction target can also exist in three forms, namely, land (or land use right), material entities and their rights and interests in the state of integration of buildings and premises. The essence of real estate in the legal sense is a kind of real right, which refers to various economic interests contained in real estate entities and various rights formed therefrom, such as ownership, use right, mortgage right, mortgage right, lease right and so on. Because it is closely related to the government's fiscal revenue and the government's excessive currency after 2008, China's real estate began to develop abnormally after 2008, which caused a serious impact and burden on the city's industry and commerce and citizens' lives. So it is best to have these index futures.
