What do you charge to manage other people's properties?

[James W.]

I have a person that has a couple properties he doesn't want to manage.

From what I gather, the tenant used to work for him and as such they have a personal relationship that is causing issues. The tenant isn't the best, and what really needs to happen is the tenant should be evicted, but he doesn't want to be the bad guy.

I'm ok with being the bad guy. Rent is late, I send out a notice. Notice is ignored, I send out an eviction. No problem.

What is the standard fee to take over all this stuff as a "Property Manager"? 

Any feedback is appreciated!
