2. Do the loan contract and mortgage contract have the same date?

1, not needed. The loan contract comes first, and the mortgage contract can be signed later than the loan contract. A loan contract refers to a contract in which the parties agree that one party will transfer the ownership of a certain kind and quantity of currency to the other party, and the other party will return the similar kind and quantity of currency within a certain period of time. After the loan contract comes into effect, the debt will be repaid. In order to ensure the performance of debts, sometimes creditors will ask debtors to provide guarantees. The mortgagor sets mortgage guarantee to the mortgagee with certain property (including real estate and movable property). When the debtor fails to perform the debt, the mortgagee may give priority to the payment from the disposal of the collateral according to law. A contract signed to ensure the realization of creditor's rights is a mortgage contract. A mortgage contract is a guarantee contract signed by the mortgagee (usually the creditor) and the mortgagor (either the debtor or the third party).
