J&R Construction Company is an international conglomerate with a real estate division that owns the right to erect an office building on a parcel of land in downtown Sacramento over the next year. This building would cost $$19$ million to construct. Due to low demand for office space in the downtown area, such a building is worth approximately $$18\mathrm{.}5$ million today. If demand increases, the building would be worth $$19\mathrm{.}7$ million a year from today. If demand decreases, the same office building would be worth only $$17\mathrm{.}5$ million in a year. The company can borrow and lend at the risk$-$free annual effective rate of $4$ percent. A local competitor in the real estate business has recently offered $$334,000$ for the right to build an office building on the land. What is the value of the office building today?
