I bought a house and went to the bank for a loan. When I signed the contract, I signed it with an average capital. Why did you receive a text message "Recover the loan principal and interest 3 135" today? There are two ways to repay the house payment, the average principal and the equal principal and interest. The repayment amount of average capital varies from month to month. That is, the principal is the same every month, so much and fixed. What changes is interest. This repayment method, in the monthly mortgage, the proportion of principal is relatively large. So the interest will be much less than the other one. Matching principal and interest means that the money paid back every month is the same. The principal is very small, and it is basically interest. Behind it is the principal. So prepayment is meaningless. If you have questions about your mortgage, you can consult your lender. Or go to the bank counter where the loan is made. They will give you a list of how much you should pay back each month, interest and principal. What is the total * * *. Very clear.
