Does the developer know that the mortgage will be paid off in advance?

Developers will know when they pay off their mortgages in advance. The lender will be notified by SMS, asking the lender to choose a suitable time to make an understanding pledge. However, if the mortgage has not been lifted, it will not have much impact, but the house will always be in a state of mortgage, and it cannot be sold or applied for mortgage again. However, after the mortgage is paid off, it is best to take time to go to the bank as soon as possible.
