I had a higher expectation for the services of a home inspector. I was under the misguided belief that they would report ANY and ALL issues with a house. But the governing body for Licensed Home Inspectors restricts wheat they can and cannot say.
For example, not mention of Mold can be made in a report as it is deemed to be a "suspected adverse environmental condition".

This a challenge for the inspector as they cannot report an problem without risking their livelihood.
My advise to buyers - Know the limits of the Home Inspectors and use third parties specialists for the items that a Home Inspector will not report on.
