Property Manager Broker Commission Split

[Kim F.]

Would you mind sharing any advice or experience that you have with paying Property Managers a commission for their work

Working for same brokerage for 5 years as a 1099 Property Manager with established properties.. Ownership of Brokerage has changed over once. Since I started managing I have tripled the business income due to adding additional properties. 

I do all of the work except for contract review by broker and they pay for the pm software and overhead of having a physical location for the brokerage (although rents collected and owner payments are all done online). I pay E&O insurance and RE renewal fees, etc.

What would you advise for commission split with brokerage? 

I would like to hire an assistant as the business is growing.  What would you advise for how they get paid? Out of my commission?
