Out of the 15 years the seller has owned the complex, there has never been a fire incident under their ownership until this year.I was planning to upgrade all the electrical anyways in each of these units, but how should I approach handling this fire incident in light of closing?

We spent a lot of money on attorneys to make sure it was worded correctly and not discriminatory in nature.

So that naturally lead me down that path.

In some pictures, the lighting is on so I can assume some of the electrical is in working order.

Then with the attorney's green light, you can proceed with an eviction through the district court.Good luck! 

The code also addresses light and ventilation.  

Heating is Electric by old radiator or fireplace with natural gas, and A/C window units though out the house.

I had a guy who could do plumbing repairs, replace shower surrounds, replace countertops, do light electrical repairs (like changing out a plug socket). 

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.

I could control the lights outside for the seating area and the fans which kept mosquitoes away.
