No use for market valuation purposes, but of use for insurable value purposes. I suppose it is out of the question to ask the client to indicate that they need cost for insurance (so-called identifying the intended use), and then leave out the irrelevant parts of the approach (so-called matching the scope of work to the intended use).I think that many appraisers realize that the cost approach is being required by their clients in order to be used for insurance. There are a few clueless appraisers who don't realize this, but they are beyond help anyways. However, most appraisers keep on doing the cost approach even when it is of no use for valuation purposes because the cost approach is required by the client. In many cases, the choice is to do the cost approah or lose the client.
