There is still a difference between second-hand houses and faster houses. There is also an evaluation price of 30%, which is the evaluation price, not the price quoted by the landlord.
If the landlord's offer is higher than the estimated price, you have to make up the money.
If the landlord offers a house with a price of 1 10,000, but the appraised price is only 800,000, then you have to pay back 30% of 800,000, that is, the loan is 240,000, and you must bring it to 760,000. If the bank only lends you 600,000 yuan, then you have to pay a down payment of 400,000 yuan for this room, which is 40% down payment.
