If you wanted to continue, I might proceed with> In this inspector’s opinion, movement was within acceptable limits at time of inspection. However, it is suggested to monitor cracks to determine if further movement is occuring. If excessive movement is suspected, you should consult a structural engineer for evaluation.
I work for a home builder and this is a common thing to see in a new home (3 years),especially if the builder uses green lumber. This is the result of shrinkage of materials. If it was structural you would see more than just caulking seperating around a window. Look for bigger signs for structural.
What Peter just said. Separating caulk alone is not indicative of structural issues. I would note this under minor / misc. notes in my summary. Check for moisture, note it and move on if nothing to report. As soon as you raise the flag of “structural” without fairly conclusive evidence YOU might find yourself having to backpeddle and looking like an amateur who just calls out every nitpicking item to cover your bo-hinney. Especially if the report is full of "get further evaluation by licensed contractor (structural engineers, etc.). Report what you see, stick to the facts, not conjecture.
