The developer forced me to pay the property fee and heating fee, which has been more than half a year since the delivery date on the contract. What should I do?

Strictly speaking, property fees and liquidated damages are two concepts. If it were me, I would handle it like this.

1, read the commercial housing sales contract carefully to see whether the developer meets the delivery conditions, mainly depending on the verification of the commercial housing completion acceptance record and the measured area table, and whether the water, electricity, gas, heating and roads promised in the contract are met.

2. If the developer fails to notify you to take over the house before the delivery date agreed in the contract, or fails to show you two certificates when notifying you to take over the house, you have the right to return the house, so the postponed date belongs to delayed delivery.

I suggest the property fee like this:

Directly hire a lawyer to sue the developer for delaying the delivery of the house before the house is closed, and ask the developer to bear the property fee and heating fee other than the liquidated damages in the lawsuit. If you close the house, just keep the official invoice.
