1. Take your ID card or valid certificate to the real estate trading center in the area where the house is located, fill in the inquiry application form (you are not sure what to check, just check all), and go to the inquiry window. The registered housing contract will have a unique record number. You can provide the record number for inquiry, and you also need to provide your own identification when inquiring.
2. Online inquiry: open a browser, search for "real estate registration information", and click the URL in the search results to enter. After entering the homepage of online real estate, click "Real Estate for Sale" on the navigation bar, and the list information of real estate currently on sale will be listed at the lower right. Enter the name of the purchased building in the "Project Name" box below the navigation bar, and click "Query" to display the basic information of the building.
It should be noted that the prices of different floors and different units in the same building are different. You can choose your own room number for filing price inquiry on the basic information page of the property.
