From my experience, having a property manager is worth it, especially if you don't live in the immediate area of the rental property. I agree the placement cost can be discouraging or a put off and not all PM are equal. So interview them, look at their ratings and reviews, talk with some of their home owners they work for, if its ok.
I currently have properties I manage myself and other properties with a PM. For each approach, I decide which tenant I accept. You can screen and select your tenant but you need to understand the screening process and what to look for and look at such as, credit scores, credit reports, rental history, income to rent ratio (income 3 times rent rate is my minimum) back ground, creating that worthiness profile.
If you are placing the tenant in order save on the PM cost, its not worth it. Either you jump in and manage your property or give it to a great PM.
Great PM has a price but so does cutting corners.
