Anyone only use property management for their properties?

[Jonathan Tea]

I'm just starting out. I currently have 1 property under my belt. It's an out-of-state property and I'm currently having a property management company handle it. So far it's been pretty positive. I'd like to get more properties and have the management company take care of those too. My strategy is buy and hold rentals, looking for cashflow. Not that interested in flipping. I already have a full time job.

I'm wondering, how many of you seasoned pros have all or a majority of your property under a property management company? Are you in one market or multiple markets? 

As a noobie who wants to scale, I'm wondering if this approach works.
