The down payment interest is 0.53% of the total amount. According to the relevant information, the interest of zero down payment house purchase is much higher than that of normal commercial loans, reaching 0.53% of the total house purchase price. Lowering the down payment will temporarily ease the financial pressure on buyers. In a short period of time, consumers not only have to repay the remaining down payment paid by the developer, but also repay the bank mortgage loan. The burden on buyers has not been reduced, but the repayment pressure is even greater.
