Good property manager terms?

[Austin Davis]

I am in the process of looking interviewing property managers. In my initial email to one of them, I asked for what they charge and he said for single family houses, they charge 1 months rent per year. I own three 4-plexes and he said that we could negotiate the terms. I would like to negotiate fair terms that incentivize the manager to run the property the way I want, which would be to fill units fast with tenants that stay long term and keeping the rent just under market rate. Any suggestions on terms, incentives and things to look out for would be much appreciated! Thanks!
