② You can inquire through the Internet: you can directly log in to official website, the local price bureau, or log in to official website, the local housing authority. After logging in to Housing Security official website, you can choose the commercial housing project you want to query, then enter the specific name of the building, then select the building and room number you want to query, and then you can query the specific pre-sale price. In general, the selling price of a house can be lower than 15% of the filing price. If it exceeds 15%, then this type of house does not meet the filing requirements, that is to say, it cannot be purchased.
