An investor wants to purchase a new office property for $$2\mathrm{.}2$ million. However, she decides whether to use a $70$ percent loan at $4$ percent interest for $20$ years.

NOI is expected to be $$150,000$ per year and increase at $2$ percent annually, the same rate at which the property is expected to increase in value. The building and improvements represent $80$ percent of value and will be depreciated over $39$ years $(1-$:$39$ per year with no mid$-$month convention for year $1).$ The project is expected to be sold after five years. Assume a $35$ percent tax bracket for ordinary income, a $25$ percent for depreciation recapture, and $20$ percent for capital gains taxes.

What would the BTIRR and ATIRR be after financing $($assume monthly mortgage amortization$)?$

$-$ Can you perform the calculations please
