Completely agree and wouldn't normally purchase a rental in these markets personally.  

I'm experimenting with several small touches to see what impact they have.

Witnessing the dissipation of substantial (multiple seven figures) personal capital, especially in efforts to steer through these turbulent times, has been a sobering experience.

I know of several excellent property managers in the North Alabama area that would service the Harvest area, including several that I've never worked with personally, but have a good rep in the area. 

Like any tool, you have to know how to use it correctly or you could get, "injured".We use it to quickly sift through multiple options - and that's about it.BP has a Rental Calculator that includeds everything you are asking about: mortgage P&I, property taqxes, home insurance and percentage for maintenance & vacancy.It also includes Cap-Ex percentage, but in our experience it's a waste of time to worry about this.

Basically your time, resources and experience will dictate this ppsf. 

All via Skill, Training, Experience and Expertise. 

So it's just personal preference and budget for a host.

I am basically a newbie but have some experience in a foreign country (Brazil).

My first property was chaotic with tenant troubles, so Ohio being a landlord-friendly state and Parma Heights being A-class location, I'm eager to get involved and experience the difference.
