1. You just helped your friend buy a house with a loan. In fact, the property right of the house belongs to your friend. You need to prove that your friend has signed the corresponding documents, clearly indicating that this is the property in your friend's personal name, and you are just helping him repay the loan as a lender.

If your friend can't repay the loan, you need to bear all the loan responsibilities. If you don't have enough funds or resources to repay the loan, you may face serious financial problems and credit problems.

Therefore, if your friend can't repay the loan, you need to contact a lawyer as soon as possible to understand your rights and responsibilities.
