You can sell it if you want. If you sell a house through an intermediary, you can discuss it with the intermediary. There are exchange vouchers in the agency. Of course, there is a charge for this. Another way is to discuss directly with the buyer, first sign a sales contract, then the buyer pays the down payment (this down payment is used to repay the bank loan), and then the bank gives you the real estate license, and then the buyer gives you the balance, and at the same time goes to the transaction transfer.
