I appraise in SD county and I can appraise land parcels anywhere in town. Including the older areas that are fully built out. Same throughout the other counties in this region. It just takes more time, effort and research than pumping out a 1004 on a tract home, and it usually requires the use of a wider geographic area and more adjustments to compensate for location and other attributes. Bear in mind that the buyers/sellers of land parcels are not the same as for properties with an existing use.
The main reason to not use a CA is if none of the market participants are using it. Which is almost always the case for existing uses. Just because it's possible doesn't automatically make it necessary to get to MV. I daresay the inclusion of a CA in most SFR assignments calling for it will be driven by the user's request, not the appraiser's need of it to get to MV.
"Cost approach was not necessary to develop an opinion of MV but is included solely at the Client's request."
If/when that's the case.
Another reason is the inaccuracy of Cost Tables or Services, in combination with the very rough approximations of architectural, construction and fixture details in the subject and comparable properties. CA is never better than a rough approximation, - unless you are going to run it off actual construction construction costs for the subject as of the effective date of appraisal - or some relatively close date, such as date of purchase (which to be accurate should be updated to cost as of effective date, only there are limits to what you can profitably accomplish). Two independent appraisers doing the CA on the same subject property for the same effective date, could not be expected to be close in value, unless they were using the same cost data.
