Consider an income property that is under evaluation for purchase with a $$468,317$ loan, $5\mathrm{.}1\%$ interest rate, compounded annually, amortized over $21$ years. The NOI at the end of year $1$ is $$56,690,$ year $2$ is $$48,304,$ and year $3$ is $51,792.$ At the end of year $3,$ the property is estimated to sell for $$556,914.$ Discount the equity cash flows over the $3-$year holding period at $10\mathrm{.}0$ percent. Using the principles of mortgage equity capitalization, what is the estimated total property value with a holding period of $3$ years?
