Is it leaking or just unstable?

The tenants were understandably concentered about the possibility of mold growth resulting from the water intrusion, so I had a test done which detected some mold.

What happens when the roof starts leaking, the parking lot needs restriped, or the fire system for the center needs a major repair?

The roof is new so shouldn’t have leaks but you never know and would like to know when a problem happens so we can get it fixed without causing more damage because it not addressed can cause more money to fix and further damage. 

it’s all cosmetic. sink basket is sorta leaking, the puddy isn’t holding well. gonna change out the sink basket instead of replacing sink, nothing is wrong with the sink entirely.

Stop the leaks, install window vents and or humidifier I have done dozens of jobs like this. 

We hired a plumber (that we have used for years) to fix a tub spout leak and toilet repair.

They just left a homeowner high and dry, when a personal residence flooded due to a pipe quietly leaking for months!

With technology and on line title records, major loan servicers are set up to detect deed transfers in major counties.  

Even if, say, the roof needs replaced, but it isn't currently leaking and keeping you from renting the unit, then you can punt that option, at least for a bit.And I also second Rob's take on going straight to the contractors.
