Legal analysis: before submitting mortgage information, banks will first check the credit records of buyers. If the credit record is not good, the bank will not approve the loan, and the buyers will be liable for breach of contract. If you are rejected because of credit problems, you can provide more proof of assets to the bank, such as deposit certificate, other property certificate or other property certificate. If the property buyers have more assets, the bank will relax the credit requirements appropriately. Secondly, if loans cannot be issued because of changes in government policies or bank regulations, buyers can file a lawsuit to prove that they are not at fault and are really unable to buy a house, thus requiring developers to return the down payment and deposit.
