In a residential area, the commercial housing needs maintenance after the warranty period, and the resettlement housing also needs maintenance. It can't be said that the commercial housing will be repaired after paying special maintenance funds, and the resettlement housing will be repaired after paying, which will affect the living environment of the whole community. It is obviously unreasonable to use the maintenance funds paid by the owners of commercial housing to repair houses for the owners of relocated households. Therefore, in a property management area, both commercial houses and relocated households should be treated equally, and special maintenance funds should be paid, that is, relocated households should pay 2% of the price of similar commercial houses to the development and construction units, which will hand them over to the Housing Authority when they receive the last batch of sales contracts.
