I don't know where you are looking at the house. If it is Chengyang, the first-hand house only needs to pay the house deed tax and the house maintenance fund. If it is a second-hand house, it needs to pay 5.6% business tax, 2% personal income tax, deed tax and the house maintenance fund. According to whether the house area and the property certificate are over five years, the tax will be reduced or increased accordingly. Does a family of three mean the couple plus the elderly or the children? If you are only an old man now, it is recommended to buy a house with three apartments. You will definitely have children in the future. If you are a couple with children, just one apartment with two apartments will be enough.
