Typical rates & fees for property management?

[Ari Newman]

I am wondering, what are other investors seeing property management charge for lease renewals and new-tenant placement?  From the people I've spoken to (in Atlanta, GA) Tenant placement seems to be a charge equal to 1 month rent, where lease renewal is anywhere from 1 month rent to no renewal fee.  Just trying to get an idea of what to expect when hiring a new manager.

Thanks

8-10 percent monthly gross rent fee, 1-200 dollar renewal and one month rent for placement
