Legal analysis: the monthly mortgage payment does not exceed 50% of the wage income at most, but the actual living ratio varies from person to person. For example, if the income is high and the cost of living is relatively low, some people are willing to repay with a higher repayment amount to reduce interest expenses. However, some people are willing to choose a longer repayment period and bear the corresponding interest, but at the same time use the funds for investment to obtain higher returns. For people with low income, the cost of living accounts for a relatively large proportion, and the mortgage is controlled below 40% of the income to ensure that the quality of life will not be reduced.

Legal basis: According to Article 41 of the Law on Commercial Banks, no unit or individual may force commercial banks to issue loans or provide guarantees. Commercial banks have the right to refuse any unit or individual to force them to issue loans or provide guarantees. According to Article 42 of the Commercial Bank Law, the borrower shall repay the loan principal and interest on schedule. If the borrower fails to repay the secured loan at maturity, the commercial bank has the right to require the guarantor to repay the principal and interest of the loan or give priority to the repayment of the collateral. Real estate or equity acquired by commercial banks due to the exercise of mortgage or pledge shall be punished within two years from the date of acquisition. If the borrower fails to repay the credit loan at maturity, it shall bear the responsibility in accordance with the contract.
