I can borrow as much as I want. To apply for a loan by mortgage, the specific loan amount needs to be combined with the actual situation. The maximum amount of bank loans is 70% of the assessed value. Generally speaking, the amount of mortgage loan is different for different mortgaged properties. Under normal circumstances, the mortgage rate of commercial housing can reach 70%, the mortgage rate of shops and office buildings can reach 60%, and the mortgage rate of industrial plants can reach 50%. Article 7 of the Law of People's Republic of China (PRC) Commercial Bank, when a commercial bank conducts credit business, it shall strictly examine the credit standing of borrowers, and ensure and guarantee the timely recovery of loans.
