A home loan, also known as a home mortgage loan, requires a home buyer to fill in an application form for a home mortgage loan to the lending bank and provide legal documents such as ID card, income certificate, house sales contract, and guarantee letter. After passing the examination and passing the certification documents that must be submitted as required, the lending bank promises a loan to the home buyer, and handles real estate mortgage registration and notarization based on the house sales contract provided by the home buyer and the mortgage loan contract entered into between the bank and the home buyer. Within the period specified in the contract, the loaned funds will be directly transferred to the account of the selling unit with the bank.
