Legal analysis: Yes, you must pay the property maintenance fund to buy a first-hand house. Commercial housing sales, buyers and selling units should sign the relevant maintenance fund payment agreement, buyers should pay the maintenance fund to selling units (developers) according to the proportion of 2-3% of the purchase price. The maintenance fund collected by the developer is the same as that of all the owners, and is not included in the residential sales income. The standard of special maintenance fund is: high-rise (including multi-storey with elevator) 9 yuan/square meter, multi-storey (including villa) 5 yuan/square meter (the standard of housing maintenance fund in various places is linked to the economic level, and the specific collection standard is slightly different); Housing maintenance fund = cost price per square meter of construction area x ratio x area. However, it should be noted that the specific standards of maintenance funds are determined by the local real estate department, so the proportion of maintenance funds varies from region to region. Fang Tianxia suggests that buyers go to the local government website or the website of the Housing Authority for enquiries.

Legal basis: Article 13 of the Measures for the Administration of Special Maintenance Funds for Residential Buildings fails to deposit the first special maintenance funds for residential buildings according to the provisions of these Measures, the development and construction unit or the public housing selling unit shall not deliver the house to the purchaser.
