How to calculate the down payment and monthly payment for buying a single apartment in Shenzhen?

If it is 400,000, the banking policy has been relaxed now. If it is the first time to buy a house, the reputation is good, and the down payment can be around 20%. That is to say, if you only make a down payment of 80,000 yuan, borrow 320,000 yuan from the bank, and make a monthly payment of 2055 yuan/month, if you mortgage for 25 years, it will be 2 1, 9 1 yuan/month.

The less you borrow, the less your monthly payment will be. The higher your loan, the higher your monthly payment. That's it.
