How to deal with the landlord's deduction of 300 health fees from the property?

First of all, you need to check whether there is any relevant clause about health expenses in the rental contract. If it is clearly stipulated, it can be done according to the requirements of the contract.

If there is no clear stipulation in the contract, you can communicate with the landlord to explain that you think the health expenses should not be borne by you, and try to provide relevant evidence to support your point of view. If the landlord still insists that you pay the health fee, you can consider asking the property company for help and seeking their advice and help.

When communicating with the property management company, you can provide relevant evidence, such as: rental contract, health cost sharing agreement, etc. , and ask for their opinions. If the property management company thinks that you should not bear the health fee, they can make suggestions to the landlord or intervene in mediation.

If the landlord still insists that you pay the health fee, you can consider consulting the relevant legal institutions to understand your rights and legal channels. In this process, you need to keep all relevant evidence and documents and follow legal procedures.
