The method of decreasing month by month is called average capital repayment method, which means that the principal will remain unchanged every month, and the interest will decrease with the decrease of your unpaid loan. The other way is called equal principal and interest repayment, and the repayment amount is the same every month. At first, the principal was less and the interest was more, and then the principal was paid more and more every month, and the interest was less and less, but the total repayment amount was the same every month.

Housing loans mainly include the following:

1. Housing provident fund loan: For residents who have already paid the housing provident fund, low-interest housing provident fund loans should be the first choice when buying a house.

Housing provident fund loans have the nature of policy subsidies, and the loan interest rate is very low, which is not only lower than the loan interest rate of commercial banks in the same period (only half of the mortgage interest rate of commercial banks), but also lower than the deposit interest rate of commercial banks in the same period. In other words, there is a spread between the mortgage interest rate of the housing provident fund and the bank deposit interest rate. At the same time, when handling mortgage and insurance related procedures, the housing provident fund loan will be charged by half.

2. Personal housing commercial loans: The above two loan methods are limited to employees who have paid the housing provident fund, and there are many restrictions. Therefore, people who have not paid the housing provident fund have no chance to apply for loans, but they can apply for personal housing secured loans from commercial banks, that is, bank mortgage loans.

As long as your balance in the loan bank accounts for not less than 30% of the funds needed for house purchase, and it is used as the down payment, and the assets recognized by the loan bank are used as collateral or pledge, or the units or individuals with sufficient compensation ability are used as guarantors to repay the principal and interest of the loan and bear joint liability, then you can apply for using the bank mortgage loan.

3. Individual housing portfolio loans: The maximum amount of provident fund loans that can be issued by the housing provident fund management center is generally1-290,000 yuan. If the purchase price exceeds this limit, the insufficient part shall apply to the bank for commercial housing loans.

These two kinds of loans are collectively called portfolio loans. This business can be handled by the real estate credit department of the bank. The interest rate of portfolio loan is moderate, and the loan amount is large, which is more for the lender to choose.

According to the repayment formula of general mortgage loans, it can be divided into two types:

I. Calculation formula of equal principal and interest:

Calculation principle: from the beginning of monthly contribution, the bank collects the interest of the remaining principal first, and then the principal; The proportion of interest in monthly payment will decrease with the decrease of residual principal, and the proportion of principal in monthly payment will increase with the increase, but the total monthly payment will remain unchanged.

It should be pointed out that:

1, the maximum amount of urban provident fund loans should be combined with local conditions;

2. For residents who have borrowed money to buy a house but whose per capita area is lower than the local average, and then apply for buying a second set of ordinary self-occupied housing, the preferential policies for buying ordinary self-occupied housing with the first set of loans shall be implemented mutatis mutandis.

Second, the average capital calculation formula:

Monthly repayment amount = monthly principal+monthly principal and interest

Monthly principal = principal/repayment months

Monthly principal and interest = (principal-total accumulated repayment) x monthly interest rate

Calculation principle: the amount of principal returned every month is always the same, and the interest will decrease with the decrease of the remaining principal.
