The age limit for mortgage loans in Qingdao is between 18 and 65 years old. This means that applicants must be at least 18 years old and no more than 65 years old. This is because banks believe that people over the age of 18 already have certain financial capabilities and repayment abilities, while people over the age of 65 may face problems such as retirement and reduced income, and their repayment ability may be affected. Therefore, banks will consider the age of the applicant when approving home loans to ensure the safety and reliability of the loan. The specific requirements of different banks may vary. You can consult your local bank or real estate agent for more information.
