I suspect this would happen if various parties were given the ability to ask questions in nearly every application for what this thread touches on - and I have major concerns about integrity (and credibility) issues involved in putting yourself in a position to defend this position if ever challenged. 

So getting one involved now and sooner rather than later is a great move on your part.

And having a property manager does not mean that you’re not directly involved with a lot of issues with your properties.Given your situation I might rather suggest a REIT investment where you get exposure to the category, but not have to deal with such a large portfolio, or just get your feet wet and see if you like being a landlord by buying a couple of properties  Randy

Understand the fees involved and calculate the total cost for an entire year of management so you can compare the different managers.
