The Culver Inc, a manufacturer of low-sugar, low-sodium, low-cholesterol TV dinners, would like to increase its market share in the Sunbelt. In order to do so, Culver has decided to locate a new factory in the Panama City area. Culver will either buy or lease a site depending upon which is more advantageous. The site location committee has narrowed down the available sites to the following three very similar buildings that will meet their needs. Building A: Purchase for a cash price of $611,000, useful life 25 years. Building B; Lease for 25 years with annual lease payments of $71,370 being made at the beginning of the year. Building C: Purchase for $657,400 cash. This building is larger than needed; however, the excess space can be sublet for 25 years at a net annual rental of $6,800. Rental payments will be received at the end of each year. The Culver Inc. has no aversion to being a landiord.
