When selling commercial housing, the purchaser and the selling unit shall sign the relevant maintenance fund payment agreement, and the purchaser shall pay the maintenance fund to the selling unit according to the proportion of 2-3% of the purchase price. The maintenance fund collected by the selling unit belongs to all owners and is not included in the residential sales income. The current deposit standards of the first special maintenance fund are: 90 yuan per square meter for high-rise buildings (including multi-storey buildings with elevators) and 50 yuan per square meter for multi-storey buildings (including villas).

Zhengzhou's housing maintenance fund = 1 18m2× 65 yuan =7700 yuan. If the maintenance fund is paid in Luoyang = 890,000 yuan × 3% = 26,700 yuan.
