Oh great, another Cost Approach Thread . . . .
It is actually Economic Obsolesence. You can include it near the bottom of the Cost Approach on the 1004. The only way to figure it out is to calculate the cost and subtract the value from the Sales Comparison Approach.
I have more experience with the Cost Approach than 99.9% of appraisers, and I know it is garbage. As we learn in Appraiser 101, Cost does not equal value.
The real Cost Approach (Not M&S) is useful to help us predict the future value trend. If a new home costs $100 per sf to build, but current homes are selling for $50 per sf, then we know that at some point, the values will creep up to the costs. This does not mean that values are going up or down. Values could be declining, or stable, but eventually will go higher. No one knows when that will happen.
It could be tomorrow, it could be 10 years from now.
M&S is a good way to CYA, but it is not an accurate indicator of actual costs.
