What are the nine expenses of property management? I hope to have a specific calculation form or process. Thank you.

1. Salaries and benefits of service personnel

2. Order maintenance cost

3. Public * * * greening maintenance costs

4. Maintenance fee for public facilities and equipment

5. Public * * * environmental maintenance costs

6. Reasonable profits of enterprises

7. Statutory tax

8. Operating expenses of facilities and equipment

9. Public liability insurance costs

The specific proportion of these things are generally the business secrets of the property management company, and generally will not appear in detail on the Internet.
