The property contract indicates that the owner's house has problems and the property company will repair it, but the contract does not indicate how to collect the property fee.

I don't quite understand what you said. There is something wrong with your house. It should be the real estate that is responsible for maintenance. Property is generally coordinated. If the property is maintained, it is not impossible;

The standard of property fee should be written into your purchase contract, isn't it the same when you buy a house?

I don't know which city you are in, and I dare not comment on the standards implemented. Please make the problem as clear as possible.
