Sonja and Sons, Inc., owns and operates a group of apartment buildings. Management wants to sell one of its older four-family buildings and buy a new building. The old building, which was purchased 25 years ago for $100,000, has a 40-year estimated life. The current market value is $80,000, and if it is sold, the cash inflow will be $67,675. Annual net cash inflows from the old building are expected to average $16,000 for the remainder of its estimated useful life.

The new building will cost $300,000. It has an estimated useful life of 25 years. Net cash inflows are expected to be $50,000 annually.
