"Mortgage" means that during the repayment period of individual housing loan, the borrower sells the house as collateral, and with the consent of the loan bank, the buyer of the house continues to repay the unexpired loan of the seller. Simply put, it is to buy and sell the house that is still mortgaged again, and the buyer of the house will continue to repay the mortgage of the seller. At present, there are two situations in the second-hand housing market in Beijing: point-to-point mortgage and inter-bank mortgage. Due to the different credit standing, loan willingness, monthly payment ability and purchase fund arrangement of buyers, buyers can apply for different loan terms, loan amounts and repayment methods according to their own needs while refinancing. In practice, the way of refinancing is that the seller repays the loan in advance, so the buyer's loan can be inconsistent with the seller's outstanding loan. \x0d\\x0d\ Specific operation process of sub-mortgage: 1. The buyer and the seller sign a sales contract to confirm in advance whether the buyer has the ability to repay the loan. \x0d\\x0d\ 2。 If the bank agrees to the buyer's loan, it chooses to apply for point-to-point lending or inter-bank lending (note: if the seller repays less than one year, it usually chooses point-to-point lending or the same branch lending; If it has been one year, you can choose to transfer money across banks). \x0d\\x0d\ 3。 The buyer applies to the bank for refinancing, submits relevant materials and pays relevant fees, including guarantee fees (the normal lending time of the bank is within three working days after the transfer). Banks usually designate their recognized guarantee companies or intermediaries to undertake the guarantee responsibility of advance payment. That is, after lending money to the buyer, if the seller defaults or the buyer defaults, resulting in the house not being sold, the guarantee company or intermediary agency shall be liable to the bank for compensation. The resulting guarantee fee in the re-mortgage loan is between three thousandths and eight thousandths of the loan amount. At the same time, the seller needs to sign a letter of commitment to the bank, guarantee company or intermediary agency, and the buyer needs to issue a letter of guarantee to the bank. \x0d\\x0d\ 4。 The application for re-mortgage has been approved by the bank (generally it takes 5 working days). After the bank confirms that it can repay the loan, the guarantee company or intermediary agency designated by the bank where the buyer applies for the loan will handle the repayment formalities with the relevant funds. \ x0d \ x0d \ 5。 After completing the loan repayment procedures, the guarantee company or intermediary agency will cancel the mortgage registration for the seller. \x0d\\x0d\ 6。 After completing the mortgage cancellation procedures, both parties will go to the housing management department for transfer accompanied by the guarantee company or intermediary agency. \x0d\\x0d\ 7。 The guarantee company or intermediary agency will collect the real estate license on its behalf, and after the mortgage registration is completed and the certificate of other rights is obtained, it will be handed over to the buyer.
