The 8 unit has required more time and energy because it had been poorly managed for years.

Do that before you spend any energy trying to kick him out.If he hasn't paid rent, you can call the police and have him escorted from the property. 

Bad electrical is dangerous.  

But always keep your core values front and center.I’m curious... now that you’ve got this momentum, what’s the next step you’re considering to deepen those relationships and keep the positive energy flowing?

The GC can handle the entire project, coordinate different subcontractors and make sure the project is completed per building codes - especially if the rehab is complex or involves multiple trades like plumbing, electrical, and carpentry.

If the home is 100 yrs old, I'm assuming it's a definite gut which is going to require new plumbing, electrical, heating, cosmetics.I spent about $140K reno on my multi family in the heights on NY ave and there were massive problems with it but it was a gut to 3 units & adding 2 bathrooms, 3 brand new kitchens 4 bathroom reno in total, all new flooring, sheetrock , insulation, framing, doors, electrical, plumbing, paint, parts of roof etc.

Seems like it could be pretty easy to throw in an electric one, no?

Again, your time and energy is better spent increasing accountability and pushing RAD to improve their staffing with individuals qualified to maximize their portfolio at this time.....and in the future spend some time and money to perform adequate diligence before you invest passively. 

A small bathroom can be gutted and drywalled new tile new electrical new shower everything in five days or 40 hours. with two guys. 

To avoid the risk management/insurance that comes with tenants' wood fire use:I'm thinking to seal the chimney cap on roof and run a cord putting an electric Infrared heater fireplace in there, so they can still open the glass and get heat and watch TV over the mantle, but can't burn anything or have any flame.
