You might even ask IL's own Attorney General, Lisa Madigan who is VERY pro-tenant and anti-investor.

I am not anti-septic just outlining things you might consider.  

Proper winterizing would have drained all water from pipes except for traps; traps get RV anti-freeze added to the water in the trap.

I've never done one, but you might be well advised to know the government has an interest in closely scrutinizing these intermediary (midco) transactions under a number of different anti abuse regimes that come complete with onerous penalties and other sanctions.

To be fair a lot of them smoke outside of their homes as they are equally as anti-smoke as I am and are respectful of their spouses and housemates.

They will check for everything to ensure safety and habitable. i.e. doors/locks, lights, detectors, windows/screens, appliances (stove with anti-tip plate), hand rails, wiring in the unit and in the basement, lead paint (if children).....etc6.

I don't know either, but it would not surprise me if more tenant-friendly environments (SF, NYC...) have anti-discrimination laws that mean you have to tread very carefully when charging higher rents and deposits.

They had some anti-gentrification people protesting it pretty aggressively. 

I am definitely not trying to be "anti tenant," but the way they both described the mold is that it is literally a "bed shaped" space where it begins and ends at the bed, from the head to the foot and top to bottom and isn't present elsewhere.
