The maintenance fund is what the owner must pay when buying a new house. After paying the maintenance fund and deed tax, he can apply for the new house property certificate.

The second-hand house can be transferred to the maintenance fund after the transfer of the real estate license is completed.

Maintenance fund, also known as "public maintenance fund" and "residential special maintenance fund", refers to the funds paid by the owners of residential properties to a special account according to certain standards for the maintenance of public parts and facilities in the property area and authorized by property service enterprises or other management units. The maintenance fund is raised by the owners of the property, who enjoy the ownership of the maintenance fund according to the proportion of payment, but the right to use it belongs to all owners, and individual owners may not withdraw all the maintenance funds from the bank. Maintenance funds are combined with specific houses, which exist and disappear with the existence of houses and do not change with the changes of specific owners. When the house property right is changed to a new owner, the maintenance fund should also be renamed from the old owner to the new owner.
