How to calculate the mortgage interest of buying a house? How to calculate the interest on mortgage loan? For example, I want to buy a house of 480,000 yuan, with a down payment of 300,000 yuan and a ten-year mortgage of 6.5438+0.8 million yuan. First of all, this suite you bought is your first property. Have you ever borrowed money before? Let's explain the mortgage interest rate and house purchase loan.

1. The interest rate of the first suite goes down 15% (equal principal and interest 10 year loan). Annual interest rate: 5.78%. Monthly repayment: 1978.56 yuan.

2. The interest rate of the second home rises 10% (equal principal and interest 10 loan). Annual interest rate: 7.48%. Monthly repayment: 2 134.80 yuan.

The interest rate of the second home is the same as that of the mortgage. If it's your first loan to buy a house, press 15%. After a one-time loan, the loan will increase by 10%.

If there is a second loan, the interest rate is the same as the mortgage.
