Shelton Co. purchased a parcel of land six years ago for $864,500. At that time, the firm invested $136,000 in grading the site so that it would be usable. Since the firm wasn't ready to use the site itself at that time, it decided to lease the land for $49,500 a year. The company is now considering building a warehouse on the site as the rental lease is expiring. The current value of the land is $916,000.
