The maintenance fund is only a part of the process of repossession, and it also needs to inspect the house to ensure that there is no problem with the quality of the house and settle all kinds of property fees. The maintenance fund is handled before the delivery of the house, and it is not redeemed if the delivery bill is not signed. Before closing the house, you need to pay attention to whether there is any problem. If there is any problem, you need to negotiate with the developer or the property. Just paying the maintenance fund doesn't mean that the house has been sealed.
