Raul Martinas, a professor of languages at Eastern University, owns a small office building adjacent to the university campus. He acquired the property 10 years ago at a total cost of $608,000that is, $70,000 for the land and $538,000 for the building. He hasjust received an offer from a realty company that wants to purchase the property; however, the property has been a good source of income over the years, and so Martinas is unsure whether he should keep it or sell it. His alternatives are as follows: a. Keep the property. Martinas's accountant has kept careful records of the income realized from the property over the past 10 years. These records indicate the following annual revenues and expenses: Martinas makes a $13,450 mortgage payment each year on the property. The mortgage will be paid off in eight more years. He has been depreciating the building by the straightline method, assuming a salvage value of $80,700 for the building, which he still thinks is an appropriate figure. He feels sure that the building can be rented for another 15 years. He also feels sure that 15 years from now the land will be worth three times what he paid for it. Rental receipts $160,000 Less: Building expenses: Utilities $27,750 Depreciation of building 18,292 Property taxes and insurance 22,250 Repairs and maintenance 9,200 Custodial help and supplies 44,000 121,492 Net operating income $ 33.503 b. Sell the property. A realty company has offered to purchase the property by paying $224,000 immediately and $33,000 per year for the next 15 years. Control of the property would go to the realty company immediately. To sell the property, Martinas would need to pay the mortgage off, which could be done by making a lump-sum payment of $114,500.
