Even the house itself contains commodities in the form of building materials such as 2x4 wall studs, drywall, concrete, shingles, and paint. Every commodity you purchase resides somewhere. We can now intelligently deduce that most of our commodities reside on a plot of land. But wait a minute, we also purchased that plot of land the house sits on. Even though real estate isn't considered a commodity item it is however similar in its attraction to a buyer.
