Suppose that an industrial building can be purchased today for $$270,000\mathrm{.}00.$ If it is expected to produce cash flows of $$27,000\mathrm{.}00$ for each of the next $7$ years $($assume CFs are received at the end of each year$)$ and can be sold at the end of the seventh year for $$326,700\mathrm{.}00,$ what is the internal rate of return $($IRR$)$ on this investment?
