The house I rented was entrusted by the landlord with property management. How to sign a rental contract?

Look at the landlord's power of attorney to the property company and see if there is a lease contract. If a lease contract is signed with the entrusted property, it shall be signed directly with the property. If not, you'd better sign it with the landlord himself. In addition, is there a rent charge clause in the power of attorney? If yes, you can give the money to the property and let the property issue an invoice or receipt. If there is no such clause, you can't give money to the property. You should pay the landlord directly and leave the evidence in your hand. It is best to transfer money by bank, with proof.
