Mortgage of unlicensed real estate after borrowing is regarded as fraud. Judging from the relevant information, it is a kind of fraud to use false real estate as loan collateral, but it is specifically punished according to the crime of loan fraud, not according to the crime of fraud. Article 193rd of the Criminal Law of People's Republic of China (PRC) has one of the following circumstances, which constitutes the crime of loan fraud. Whoever defrauds a bank or other financial institution of loans for the purpose of illegal possession, if the amount is relatively large, shall be sentenced to fixed-term imprisonment of not more than five years or criminal detention, and shall also be fined not less than 20,000 yuan but not more than 200,000 yuan. If the amount is huge or there are other serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than five years but not more than ten years, and shall also be fined not less than 50,000 yuan but not more than 500,000 yuan.
