Paul is the manager of a motel. As a condition of his employment, Paul is required to live in a room on the premises so that he is there in case of emergencies. Paul considers this a fringe benefit, since he would otherwise be required to pay $600 per month rent. The room that Paul occupied normally rents for $60 per night, or $1,500 per month. On the average, 90% of the motel rooms were occupied. As a result of this rent-free use of a room, Paul is required to include how much in gross income?
