What is the cost of an HVAC system vs. a heat pump vs. forced hot water vs. baseboard and what is the cost to the tenant? 

Just to add ,  not every inspection covers a visual of the septic tank . if they run the water and all mechanicals, they are working fine . other than a visual there are no signs of it not working . 

The house is rented to college students, with the parents paying and dealing with everything.The house had a burst pipe and water damage in the shared bathroom in August of 2023.

Do I need to contact the city of Chicago to have the water shut off or is this something I can do myself? 

Usually as long as their are no life threatening issues (no HVAC, windows won't open, no hot water), the housing authority will began to pay the rent and give you time to address the required repairs.

I am getting between 0 to 1 "warm" leads per day.

For emergencies (fire, water, structure) they should call Latchel who then, in theory (again, never had to test it yet...thankfully!)

Most of your issues sound water related.

It's funny, I couldn't find a similar warm off-white in the BM book, but they have no problem mixing it for me.
