Mr. Ford,
As usual, I tend to disagree with everyone else on this. If you are forced into completeing an approach then under USPAP your work doing that approach has to be credible even if the results stink. This means your land / site value (which I sort of suspect you were required to have provided even if you did not do a Cost Approach.. as it is a Fannie requirement) has to be supported. Your depreciation has to be supported. The entire approach has to be supported.
The above is exactly why appraisers should not be getting forced into providing approaches not relevant to the subject property for the intended use via blackmail. You know, I know, nuts.... everyone that responded knows they are wanting it for insurance purposes and nothing else. To comply with USPAP, this forces the appraiser into an extreme amount of work they did not bid for in the fee agreed to. Or, the appraiser completes a pulled out of their rump approach, with no to little support for anything in it, and uses some trumped up statement about giving the approach little to no weight as if that excuses their development of the approach failing to comply with USPAP. Mainly they have absolutely nothing to support that depreciation estimate in their work file. Most of them also have absolutely nothing, or something completely inappropriate, to support the land / site value estimate.
Bottom line? All of this is wrong. It is all symptomatic of an entire industry that has been beaten down like a bunch of dogs. Not allowed to actually charge for the work involved and needed to comply with the standards of the industry, and everyone involved coughing and looking the other way because they are stuck in the same boat with all involved giving up. All except an appraisal board that nails industry members hides to the wall when they get a complaint and their entire approach fails to comply with USPAP due to no work file evidence that they properly extracted out that depreciation and those land / site values when it was complex to do so for a property that it shouldn't have been required at all anyway.
