Example: Buy a house of 120 square meters at a unit price of 20,000 yuan.
120X20000=2400000 .
2400000X0.3 = 720000 down payment
2400000-720000= 1680000 loan.
The existing provident fund is 40,000 x12 = 4.8 million yuan, which can be borrowed from the provident fund.
1680000-480000 =1200000 commercial loan.
