Legal analysis: 1. After marriage, the man repays the loan with his personal property before marriage, and the woman has no right to divide the house. 2. If the loan is repaid with the salary obtained after marriage (the property obtained after marriage belongs to the husband and wife jointly, unless there is a clear agreement), the woman can divide the part of repayment after marriage when divorcing; 3. Both parties agree that the property obtained after marriage belongs to the individual, and the man repays the loan with the property obtained after marriage, and the house belongs to his personal property.

Legal basis: Civil Code of People's Republic of China (PRC).
