Question: The "Opportunity Cost of Down Payment + Moving + Closing" was characterized in class as a very real annual cost of home ownership. Your friend, however, remarks, "I don't really see this as a cost of owning a house. Nobody has to be paid this cost. It's just a reflection that your broker's statement about the value of your financial portfolio is not as great as it would have been if you'd continued renting, but that's not really a cost." How would you respond to your friend's statement? Explain fully.
