A group of private investors borrowed $30 million to build 310 new luxury apartments near a large university. The money was borrowed at 7% annual interest, and the loan is to be repaid in equal annual amounts (principal and interest) over a 50-year period. Annual operating, maintenance, and insurance expenses are estimated to be $5,000 per apartment, and these expenses are incurred independently of the occupancy rate for the apartments. The rental fee for each apartment will be $13,000 per year, and the worst-case occupancy rate is projected to be 75%.
