When you are purchasing a home, one of the most important steps you can take is to have a professional inspector evaluate the property. The inspector’s job is to point out flaws and defects on the property, especially if they will impair your ability to use the home. Major problems are referred to as structural or mechanical defects and include the roof, foundation, and HVAC systems. These are critical parts of the home that you would expect to be in good working order when you are considering a purchase. However, over the year’s buyers have begun to lose sight of the purpose for the home inspection, and it is becoming more common for their repair requests to be unreasonable.
