Recently during an inspection, I was asked why I spend a great deal of time looking in the attached garage. I stated that typically we put 2 cars in the garage (approx $55,000 value). We store many outdoor items and kids toys in the garage (approx $2,500 value). And some of us just plain hang out in the garage. Whether its working on those cars, doing some repairs to an item, or maybe entertaining in the summer when it is raining outside. I would consider the garage just as important and the house itself.
