The home is empty and the lights and water are off.

On my first purchase (personal home) inspector went to the water heater and it wasn't lit and inspector didn't even try to light it, so he just checked the box as 'needs addressed' and moved on.The only other time I had an inspection on a purchase: inspector noted a few missing shingles with no more comments other than missing. 

I just got back from my local grocery store, and there is plenty of TP, water, and hand sanitizer to go around.

I ALWAYS have separate pros inspect the roof, HVAC, structural (if something is seen that warrants it), sewer main (or, septic, including separate sewer scope for drainfield AND perk test), and water well (bacteria and pump flow, etc.), if not on public water. 

We also have a lot of homes with a lead water pipe, which needs to be replaced, which usually means digging up the front yward to the street.

The tenants on the property i'm looking to buy are reporting that they need to add water to the toilet after use in order to get it to flush and often that results in water coming up from the bathtub. 

The most cost effective way to treat for any airborne virus, is to use bleach according to food safety specs or regulations.A bleach and water solution used for cleaning, is your friend.

I have already cannibalized the property and used the hot water heater, stove etc in other rentals. 

Call the local water authority and get some actual numbers.You're forgetting CapEx.
