I really wanted to use a PM, but at this point I'm seriously contemplating just letting my RE agent list it, screen the tenants & get a good handyman, plumber, electrician etc. to handle whatever issues come up. 

No more than you should become a master electrician, master plumber, HVAC tech,  insurance agent, loan officer, and maybe other licensed people.   

I am also a licensed electrician and very familiar with construction and project management.    

The issue was electrical and a licensed electrician made the repair on a GFCI in a bathroom. 

Establish a local network of trusted professionals, such as a handyman, plumber, electrician, and a local real estate attorney who can address urgent issues promptly.

@Steele Kruzel if you are looking for a local plumber, electrician, title company, CPA, etc....then we should check with other investors in our market. 

(I'm not an electrician so I rely on others for this info) I'd ask the electrician to look at the appliances in your unit to make sure the electrical supplies from the new box to the unit will be safe.

You would be exposed to doing work without a permit, the cost of the actual permit and, worst case, having to rip it all out and have a licensed plumber/electrician do it again.I've heard most municipalities around my area no longer charge the work without a permit fine.

And yes plumbers , electricians , handymen can be expensive , you have 2 options pay someone , or repair it yourself . 

Electricians are truly my hardest find.
