This process takes some time, mainly because the bank needs to conduct a series of audits and confirmations, and the bank needs to examine and approve the loan application of the buyer to ensure its repayment ability and credit status. At the same time, the bank also needs to evaluate the house to confirm whether its value and collateral meet the requirements. All these tasks will take some time to complete.

After the approval, the bank will transfer the money to the seller's account. This process also takes some time, because banks need to deal with a lot of transfer and settlement work.
