A developer plans to start construction of a building in one year if at that point rent levels make construction feasible. At that time the building will cost $1,400,000 to construct. During the first year after construction would take place, there is a 60 percent chance that NO/ will be $180,000 and a 40 percent chance that the NOI will be $91,000. In either case, NO/ would be expected to increase at ? percent per year after the first year. Required: How much should the developer be willing to pay for the land if he wants a 12 percent rate of return? (Round your answer to the neorest whole dollar amount.)
