I am the landlord, and the contract stipulates that the property fee shall be paid by the lessee, but the lessee is unwilling to pay the property fee. What can the property company do to solve it?

According to the property management regulations, the landlord has the responsibility to protect the lessee of the house. The property management fee shall be borne by the owner according to law. Although the contract between you and the tenant is agreed to be paid by the other party, this contract belongs to the agreement between you and the tenant and is not binding on the property company. Therefore, the property company can finally recover the arrears from the landlord. I suggest you take the initiative to urge tenants to pay property fees in time to avoid greater losses caused by liquidated damages.
