Stemway Company requires a new manufacturing facility. It found three locations; all of which would provide the needed capacity, the only difference is the price. Location A may be purchased for $500,000. Location B may be acquired with a down payment of $100,000 and annual payments at the end of each of the next twenty years of $50,000. Location C requires $40,000 payments at the beginning of each of the next twenty-five years. Assuming Stemway's borrowing costs are 8% per annum, which option is the least costly to the company?
