Ed owns Oak Knoll Apartments. During the year, Fred, a tenant, moved to another state. Fred paid Ed \($1,000\) to cancel the two-year lease he had signed. Ed subsequently began renting the unit to Wayne in the same year. Wayne paid the first and last months’ rents of \($800\) each and a security deposit of \($500.\) Ed also owns a building that is used as a health club. The club has signed a fifteen-year lease at an annual rental of \($17,000.\) The owner of the club requested that Ed install a swimming pool on the property. Ed declined to do so. The owner of the club finally constructed the pool himself at a cost of \($15,000.\) Which of these amounts must Ed include in gross income during the current year?
