Credit cards cannot be used to invest in real estate. If a customer invests in real estate, it may be frozen by the bank, but it can be used when paying the deed tax. The deed tax is paid directly to the relevant state departments, not used to pay the purchase price.

Calculation of house deed tax: house deed tax = total house price * tax rate. If the construction area is less than 90 meters, it shall be paid at the rate of 65438+ 0% of the total house price; If the construction area is 90- 144 square meters, it shall be paid at the rate of 65438+ 0.5% of the total house price; If the building area is above 144 square meters, it shall be paid at the rate of 3% of the total house price.
