Property transfer can be mortgaged if you get the real estate license, and there is no specific time limit. However, the mortgaged property should be within the scope of the property that can be mortgaged according to the law. If there is any property mortgage, mortgage registration is required, and the mortgage right is established at the time of mortgage registration.
Legal objectivity:
Article 394 of the Civil Code guarantees the performance of debts. If the debtor or a third party mortgages the property to the creditor without transferring the possession of the property, if the debtor fails to perform the due debt or realize the mortgage according to the agreement of the parties, the creditor has the right to be compensated in priority for the property. The debtor or the third party specified in the preceding paragraph is the mortgagor, the creditor is the mortgagee, and the property that provides guarantee is the mortgaged property.
