I have the key, but I haven't checked in yet. Do I have to pay the property fee?

The property fee is charged on the day when the house is actually handed over, because you have already taken the key, which means that the house has been handed over, and whether you move in or not, the property fee will be included.

Of course, if you buy a second-hand house, the original owner defaults on the property fee and needs to make up part of it before you can move in.

Regarding some standards for charging property fees, you can take a patient look at the regulations:

Seventeenth "measures for the implementation of property management fees"

The property management enterprise shall sign a property management service contract or agreement with the owners' committee or the owners and users, and clarify the relevant service contents, charging items and charging standards. The agreement on fees in the contract or agreement shall comply with the relevant provisions on price management.

Without the consent of the owner and user, the property management enterprise shall not collect the property management service fee for more than six months in advance at one time, nor shall it collect the deposit, security deposit and other fees for long-term occupation (more than one year) from the owner and user without authorization.
