I have heard that there is an ultraviolet light you can put in your AC unit and it will remove smells.

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?

The point of these professionals is that they were to warn me about stuff like this.

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.  

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.

That might work for a light rehab, but if you’re reconfiguring walls, adding new kitchens and baths etc., then $25/ft2 probably ain’t even in the ballpark.
