Any question that you have! Your home inspector is there to help you make sure you’re purchasing a high-quality home that’s free of major problems. A great home inspector will be used to answering any and all of your questions. That’s their job. However, avoid questions about cosmetic issues – you don’t want to waste time. Focus on asking questions about the most critical (expensive) aspects of the home, such as the wiring and plumbing, internal structure, major appliances, and other such systems.
