The maintenance fund is a reserve fund. If the public area of the building is broken, it will be repaired and the money will be withdrawn from it.

Someone buys a second-hand house in this property. If the maintenance fund of this property has been used, it needs to be paid again and made up.

The maintenance fund is generally tens of dollars per square meter, such as 80 square meters, 40 yuan per square meter and 3200 yuan.

However, there is no agreement standard in this country, which is based on the local economic situation and the specific real estate situation. So you have to ask the Housing Authority about this.

Then the question of who should pay is generally written in the contract after buying a house. There is no rule that says who must pay.
