1. Interest rate change: The mortgage interest rate is usually adjusted according to the policy changes of the central bank. If the central bank lowers interest rates, your monthly repayment may be reduced.
2. Change of loan term: The repayment period of mortgage is generally twenty or thirty years. If the repayment period is over 5 years, the repayment period will be shortened and the monthly repayment amount may be reduced.
3. Changes in capital cost: The capital cost of a bank refers to the cost that a bank needs to pay to obtain loan funds, which is generally closely related to the market interest rate. If the bank's capital cost is reduced, your monthly mortgage repayment may be reduced.
4. Adjustment of repayment methods: In some cases, banks may adjust repayment methods, such as early repayment and deferred repayment. These adjustments may lead to changes in the monthly repayment amount.
It should be noted that the change of monthly mortgage repayment amount may be caused by one or more of the above reasons. If you want to know the specific reasons, it is recommended to consult the relevant staff of the local CCB, and they will give you an accurate answer.
