Unrealistic Inspection Expectations

Climbing up on the roof of a large commercial building and looking at the HVAC units lined up there, it struck me how unrealistic some buyers are when they hire us to inspect commercial properties.

This client only hired us for a half day despite our office suggesting that it would not be nearly enough time.
The client said they just wanted the main items looked at. Everyone has a different idea of what that would include.

So what are the main items? Foundation, roof, roof structure, electrical, HVAC, plumbing, bathrooms, exterior, structure?
Just the roof, the electric panels and all the HVAC units along with the furnaces and their components used up every minute, in fact every second of the half day.

The building was the size of 20 houses, costing about the same as ten houses and they thought an inspection price equivalent to about three houses was too much to spend, so went and hired us for four hours!
About the same time as we would spend Inspection a 3000 SQ Ft house.

We are really good at our job, we do find problems
and we find more problems if we are given the time!
