If you don't take the key, you have to pay the property fee.

Legal analysis: after the rough house is closed, if a property service contract is signed, the property fee shall be paid according to the agreement in the contract. If there is no agreement in the contract, the property fee shall be charged when the house is closed. 1. When the owner goes through the check-in formalities at the residential property management office and the owner obtains the key to the new house as the beginning of the owner's check-in, then the owner should start paying the property management fee at this time. 2. After the owner goes through the check-in formalities, the public service fee for property management shall be paid by the owner or user on a monthly basis. For owners who have purchased but have not moved in, they will pay 50% of the public service fee for property management within one year. At the same time, in order to prevent some real estate speculators from leaving their houses idle for a long time, it is stipulated that those who have not moved in after one year will pay 100%. 3. National laws and regulations do not stipulate how long the property fee must be paid, so the time for paying the property fee can be indicated in the signed property management contract. 4. After receiving the occupancy notice issued by the developer, the owner begins to pay the property management fee according to the time specified in the occupancy notice, and all expenses and responsibilities of the house after this time shall be borne by the owner himself. In other words, from that day on, all the rights and responsibilities of the house belong to the owner.

Legal basis: Article 41 of the Regulations on Property Management, the owner shall pay the property service fee according to the agreement in the property service contract. If the owner and the user of the property agree that the user of the property shall pay the property service fee, the owner shall bear joint and several liability from the agreement. Property that has been completed but has not been sold or handed over to the property buyer shall be paid by the construction unit.
