1Article 12 of the Provisional Regulations of the People's Republic of China on the Assignment and Transfer of Urban State-owned Land Use Rights stipulates: "The maximum term for assignment of land use rights shall be determined according to the following purposes: (1) 70 years for residential land; (two) fifty years of industrial land; (three) fifty years of land for education, science and technology, culture, health and sports; (four) forty years of commercial, tourism and entertainment land; (five) comprehensive or other land for fifty years. "

It should be noted that some of the above years refer to the highest year. When transferring land, the state may also limit the service life of commercial land to 40 years and industrial land to 50 years. The maximum service life of commercial land is 40 years, and that of industrial land is 50 years ...; On the other hand, if the commercial land is more than 40 years and the industrial land is more than 50 years, it does not meet the statutory time limit and is not allowed.

In your case, it is a single-family villa. It depends on what the land use is when the government signs the transfer contract with the developer or individual. 50 years is certainly possible. Residential land not exceeding 70 years (or residential land), even if it is only signed for 20 years, as long as you are willing to buy it.
