How much do property managers typically charge?

[Frank Shaw]

I have no experience hiring a property manager. How much do they typically charge? What are their primary reaponsibilities? I believe their biggest benefit to a landlord is keeping it n top of rent collection and serving eviction notices ASAP. Also they can handle issues with tenants and provide quick attention.

 Given I am a lender and have seen 1000's of rent rolls across the nation, IMO this number will range from 8-12% depending on the factors @John Warren mentioned above.
