The appraisal technique best suited for special use properties such as a county courthouse is:

The cost-depreciation approach is the most suitable appraisal technique for special use properties like a county courthouse because it focuses on determining what it would cost to replace or reproduce the property, minus any depreciation. This method is particularly effective for unique properties that do not frequently sell on the open market and have limited comparable sales data, which is often the case for government and institutional buildings.

For special use properties, the cost method allows appraisers to evaluate the expenses associated with constructing a similar building, including land acquisition, materials, labor, and any other costs required to turn the property into a functioning equivalent. This is significant because these properties typically do not generate income in the same manner as commercial properties, making the income approach less applicable. Additionally, the sales comparison approach relies on comparing similar properties that have sold, which may not be feasible if there are not enough comparable sales for such unique structures. The gross-income-multiplier approach, which involves using income data from rental properties to establish value, is also not relevant for a courthouse since it does not operate as a profit-generating entity.

Using the cost-depreciation approach provides a more accurate assessment of value for special use properties by focusing on their specific characteristics and construction costs, making it the preferred choice in
