Why do many landlords not hire management?

[John Liaaz]

I notice that it's a mixed bag when it comes to management on here. Half prefer to manage all their properties themselves and the other half won't touch a property without a manager/management company. Why is this such a polarizing topic in real estate investing?

Coming from a small business world, I couldn't imagine owning my business and doing all the work AND being on call 24/7 for customers. I never had any issues hiring employees and managers. So when I started real estate, that's the first thing I did upon acquiring a new property, started looking for management companies. I was surprised when I came to online forums to find that so many people DESPISE property managers and do everything themselves. 

I have manager for my small business, I'm paying him $40k+ a year! I pay that because it makes my life easier, I don't want to deal with a bunch of min wage employees and customers asking for me. Same thing for tenants.

It seems to me that many real estate investors are opposed to management it unlike your average small business owner.

What would be the reason for that?
