In the absence of a formal purchase contract, the developer has to pay the house, should the property fee be collected, and when will the property fee be calculated?

According to your meaning. You can hand over the building without signing a contract. I would like to ask which city you are in, whether you bought an existing house or an unfinished building. Generally speaking, you have to sign a house purchase contract within 14 days after the deposit before you can hand over the building. Why haven't you signed the contract yet? . Looks like a big problem. The property fee is paid after you check and accept the building (the maintenance fund is required for repossession, and the decoration deposit has never been heard of).
