Paying the deed tax does not mean that the mortgage will be paid. The two are different procedures, involving real estate transactions and loan applications respectively. Deed tax is a tax that home buyers must pay, usually within a certain period of time after signing a home purchase contract. A mortgage loan is a mortgage loan that a home buyer applies to a bank to pay for the home purchase.
Deeds and mortgage loans need to be handled separately. You need to meet both the deed tax payment requirements and the bank's loan requirements, and pay attention to market dynamics and policy changes in order to successfully obtain a mortgage loan.
