But you can find a second-hand house dealer to handle the transfer. You need to say the specific cost yourself. In fact, when they apply for re-mortgage, they pay off the mortgage of the house first and then apply for another person's mortgage again. So the charge will be higher. Changing the name requires a new deed tax.
If you have paid off the mortgage, you don't have to pay any fees, just do a notarization and you can transfer it to others.
