Property Management Fees: Conflict of interest?

[Leon Green]

As a property manager I'm familiar with many trends in fees/revenue generating practices that property managers charge. Some of these practices do not align the property manager and property owner's interest. For example, when a property manager keeps late fees instead of passing on those late fees to the property owner, the property manager benefits when the property owner potentially incurs fees for not being able to pay their mortgage on time. I'd like to hear your thoughts on what property manger fee practices you think are fair and which practices you think create a conflict of interest.
