Excuse me, when did the property fee of residential quarters start to be collected?

The property fee is calculated from the moment you hand over the house. The property fee before delivery is paid by the developer. When you move in, you have to pay the full property fee, and the vacant house pays part of the property fee, which varies from place to place. If you don't pay the property fee before handing over the house, you don't have to pay it. If the developer doesn't pay, you have to pay yourself.
