If the seller resists, use the tenant instability as leverage to renegotiate terms or request an escrow holdback.

And as corporate layoffs in October were at their highest for the month in 22 years, we have some rough waters ahead in terms of consumer discretionary spending.

I'd check the water shut off valves (under sinks) - if they are "old" knob style, id try to turn them to shut off the water and see if they leak (they do tend to do it over time) - replacement can be costly because it will require water shut off to the entire building (unless you have the individual main water shut off) - it will have to be done thru HOA, increasing cost. 

Some old buildings have old floor drains with p-traps and if there is no water in it the sewer gas could come in and make it's way to the vents.

I put a new well in back lot to feed water to all new buildings but since I have recently sold that property along with two other duplexes and retained rights to use water lines I put in for a monthly fee.  

I know to check shutoff valves the water should be turned off.
