The property fee in the previous property contract was proposed by the property. What standard should property fees be paid?

The standard of property management fee shall be subject to the agreement in the property management contract or the commercial housing sales contract. Developers and property management companies are not allowed to raise prices unilaterally unless the government adjusts prices. Both parties shall implement the property management fee according to the standards agreed in the property management contract. If one party changes it without authorization, it shall bear the liability for breach of contract: it can be mediated by the price department or settled through arbitration or litigation. The adjustment of property management fees must meet the relevant requirements, such as occupancy rate, the passing rate of owners' meeting, etc., and it is not necessary to go up if you want.

This depends on the specific situation. General property let you vote, you give up. If there is an agreement, the new agreement shall prevail. If you don't agree, follow the original execution.
