60 years old. According to the Interim Measures for the Administration of Personal Loans, the inquiry shows that:

1. When the borrower applies for housing mortgage loan or mortgage loan, the loan term+current age shall not exceed the bank loan age limit, that is, 60 years for men and 55 years for women.

2. The longest term of provident fund loans shall not exceed 5 years after the borrower retires. If a man retires at the age of 60, the longest loan period can only be extended to the borrower's age of 65, and the longest loan period can only be extended to the borrower's age of 60.

3. So the oldest female mortgage is 60 years old.
