I rent a house and ask for an invoice when I pay the property fee, but the property said that I must provide a copy of the rental contract before I can issue an invoice. Is this reasonable?

Unreasonable, but after renting a house, you have to go to the residential property for handover. The property will keep the relevant information of the tenant, including a copy of ID card, rental contract, etc. Because now the national census is basically looking for a property, and the property needs to know all the residents in the community. Maybe you didn't provide relevant materials. In order to understand the living conditions of the house, the property is intentional. If you really don't want to provide it, you can ask the landlord for help.
