If you want to buy a house, you need to check whether there is room information in the place where you are registered, just check whether there is a room in the city where you buy a house. Even if there is a house in my hometown, it is also the first suite, so I need to check the property where the household registration is located. If it is required to check the city where the house is purchased and the place where the household registration is located, if there is real estate in the place where the household registration is located, it will be recorded in the number of houses purchased.
