Based on the initial asker's questioin, how to sell a house still with mortgage.?

Here is the example from my question. If I bought a house in Jan and started paying mortgage, somehow need to sell in March. The new buyer pay me off with cash, which means he does not need to get loan from the bank. will the bank allow me to pay off the mortgage debt in one go and so soon, so that the bank actually can not earn much interests from my mortgage as it has only been 2 months. Do the major banks in aus allow earlier payment for loan or mortgage?

The person who purchased the house is a fool as they do not have clear title to the house.

Normally, when you sell a house, the buyer/rep and or solicitor turns up with the cheque. they give your money to your solicitor who gives the bank their share and gives you the rest, less their fees.

Thus, the bank also signs that you have clear title to the house and can pass that title to the house.

Usually, if the bank loans you money to buy property, they have a lien (?) on the title to the property that declares that they have an interest in the property,aka it is being used to secure a loan they made to you.

Only a fool would then pay you cash for the property.

yes, you have the right to sell your home and pay off the loan even if its only been a couple of months.
