How much should bookkeepers cost?

[Abdul Lateef]

Currently looking to outsource bookkeeping/accounting tasks to a bookkeeper. I am realizing a difference between costs of services.

How much should it cost me to outsource to a company (not a freelancer) if i have a couple if properties. And how many hours does it reasonably take for a bookkeeper to oversee a renter property per month if I already have a property manager?
