Why do you have to pay the real estate fee in September of a year?

Look at local government documents. Some local documents stipulate that only three months' property fees can be collected in advance.

(Take Article 9 of the Measures for the Administration of Xi Property Service Charge as an example: the property service fee is charged on a monthly basis.

If it is really necessary to get it in advance, it can not exceed three months at most. )

If you can't find a local certificate, you can go to the property management office of the local housing authority.

Ask this property company if it is appropriate to do so.

(In addition: Why do you say that the house in September 2002 17 has to pay the annual property fee?

Does it mean that 12 was charged for the whole year? )
