If the mortgage interest rate drops, the original purchase will not be reduced.

Mortgage interest rates are composed of LPR + floating basis points. For example, the current loan interest rate for buying a first home can reach 4.1%, which is LPR-20 basis points, that is, 4.3%-0.2%=4.1%. After the mortgage is approved and the loan is issued, the floating basis point is a determined value. No matter how the LPR changes in the future, the floating basis point will remain unchanged, and the mortgage interest rate is the changed LPT + floating basis point. For example, the current interest rate is 4.1%, and the floating basis point is -20 basis points. Then no matter how LPR changes in the future, the interest rate will always be equal to LPR-0.2%.

Secondly, after the mortgage loan is approved, the mortgage interest rate will change once a year. Most banks adjust it on January 1 every year, and a few banks adjust it based on the lending time. . No matter which time it is based on, every time the interest rate adjustment date comes, the bank will automatically calculate the new mortgage interest rate based on the latest LPR and floating basis points, and then calculate the monthly payment based on the new mortgage interest rate.

Therefore, only the LPR one month before the interest rate adjustment date will have an impact on the interest rate. That is to say, for most banks, only the LPR on December 20 will affect the interest rate adjustment. The intermediate LPR adjustment is meaningless to home buyers who are still making monthly payments.
