Armor Investment Company is considering the acquisition of a heavily depreciated building on $10$ acres of land. It expects to rent the building as a storage facility and expects to collect cash flows equal to $$100,000$ next year. However, because depreciation is expected to increase, Armor expects cash flows to decline at a rate of $4$ percent per year indefinitely. Armor expects to earn an IRR on investment return $($r$)$ at $13$ percent.
