Seven years ago, you paid $324,800 to purchase a rental house. the maintenance expenses average $200 a month and property taxes
Mariulka [41]

The value that would be assigned to this house if you decide to use it as your office would be $ 425300

<h3>How to solve for the value of the house using opportunity cost</h3>

To get the value of the house, you have to get the opportunity cost of the house. This is the foregone alternative or benefits forgone due to another choice.

The formula is opportunity cost = Apprised Value - Selling costs

The apprised value = $439,500.

selling cost =  $14,200

$439,500 - $14,200

= $ 425300

Hence the value that should be assigned to it is $ 425300
