Oliver Kamp has just made the final payment on his mortgage. He could continue to live in the home; cash expenses for repairs and maintenance (after any tax effects) would be $500 monthly. Alternatively, he could sell the home for $200,000, invest the proceeds in 5 percent bonds, and rent an apartment for $12,000 annually. The landlord would then pay for repairs and maintenance. 

Prepare two analyses of Kamp’s alternatives, one showing no explicit opportunity cost and the second showing the explicit opportunity cost of the decision to hold the present home.
