Case study
Paradise Land Management Company
Paradise Land Management owns and operates hotels and apartment complexes near a major metropolitan area. They want to expand operations in the near future, the goal being to increase net earnings before taxes. Two alternative expansion opportunities are under considerations: the Densmore complex and the Highgate project. Both projects involve the purchase of land on which apartment building would be constructed and operated.
The site for the Densmore complex is situated in a respectable, quite, sparsely populated residential neighborhood. Land for the 70-unit complex can be purchased for $60,000. Building costs are estimated at $1,680,000. Anuual maintenance costs would amount to $30,000. Apartment units would rent for $410 per month. Paradise is also conidering constructing a recreation facility nearby. It would cost $100,000 and would service both Densmore residents and the residents of the company owned Paradise west, the only existing apartment complex in the neighborhood. Paradise west, with 120 units renting for $290 per month, has had an average occupancy rate of 84% for the past three years. The addition of Densmore and the recreation facility are expected to increase Paradise West's occupancy rate to 90% (probability 0.6) or 95% (probability 0.4). Densmore's occupancy rate is expected to be 90% (probability 0.5), 85% (probability 0.3), or 80% (probability 0.2).
The highgate project calls for 400 units to be constructed on land costing $220,000 in a high density population neighborhood with many competing apartments. Building costs would be $4,200,000. Rental revenue per unit would be $240 per month; anuual operating costs would be $150,000. Highgate's occupancy rate is expected to be 90% (probability 0.2), 80% (probability 0.5), or 70% (probability 0.3).
