About heating fee and property fee

If there is no agreement in the contract, the property fee shall be paid by the owner (that is, the big landlord). According to the property management regulations, the property management fee of the rented house shall be paid by the owner, and if otherwise agreed by both parties, it shall be paid by the agreed party. Accordingly, there is no agreement that the owner should pay the property fee.

It's hard to say about the heating bill. Who usually pays with whom. Of course, there is also a landlord, but before you, the landlord only said that he had paid the heating fee for three months, not the late fee, so it is normal for you to pay the late fee.
