You can refer to the following process for trading:
1. Mortgage loan: The simplest and most direct way is to sell or transfer personal housing to a third person, and apply for personal housing loan to change the loan term, borrower or collateral.
2. Pay off the remaining loan with the buyer's down payment: this is the most widely used mode in second-hand housing transactions at present. This method is suitable for the case that the original owner's loan amount is low or the remaining loan amount is small after a large amount of repayment. Usually, the buyer will recognize the down payment of 30% to 40% of the total turnover of the property, and the seller can pay off the remaining loan with the down payment of the buyer, and then cancel the mortgage registration of the property and make the next transaction.
3. Use the bank loan to pay off the remaining loan: If the seller wants to pay off the loan before selling the property or the buyer is optimistic but unwilling to buy the property with outstanding loan, this method can be adopted. But the premise is that the homeowner can apply for a loan only if he has collateral (such as other real estate) recognized by the bank. In this way, the homeowner can lend a certain amount of money to the bank through mortgage loan to repay the real estate loan he wants to sell, thus contributing to the success of the transaction.
Legal basis: Article 221 of the Civil Law of People's Republic of China (PRC) stipulates that if a party signs a house purchase and sale agreement or other agreement on real property rights, it may apply to the registration authority for advance notice registration in order to ensure the realization of future real property rights. After the advance notice registration, if the obligee without advance notice registration agrees to dispose of the real estate, the real right effect will not occur. After the advance notice registration, the creditor's rights are extinguished or the application for registration is not made within 90 days from the date when the real estate registration can be carried out, and the advance notice registration is invalid.
