>>Personally, unless I am having a difficult time with an oddball appraisal, I find that the cost approach is not useful 99.9% of the time.<<
mmmh.
If I told you that there were court cases where the judges ruled that no single approach to value was "better" than another and that the aggregate (all three) was given weight in their decision favoring the client of an appraiser who performed all three approaches over a the appraiser who used a single approach to value, would you ignore that fact?
For new construction in a newer subdivision of uniform houses where you do the sales approach only, and I do the cost approach only using local builders information, I promise you, I will be just as close as you are day in day out.
And if I can do that, then I can do the same for a 5 year old house. How about a rural property? I just turned in today an appraisal of a 4,418 SF home, 15 years old, (4) barns, 1200' long concrete driveway, on 138 acres. It sold in 1997 for $630,000. Comps? 3100 SF house, same age, equal barns but with additional poultry barns, 45 acres ($695,000); 230 acres with two older houses ($710,000); and 4,800 SF 6 year old house, additional house, shop, on 260 acres ($758,000) These are the ONLY rural residential sales in that school district in the past 2 years of over $400,000.
Do you really think the sales approach can be used without using COST related methods???? And do you not think the Cost Approach is just as valid?
Judy is right, just do it on a URAR and go on. But don't gloss over the Cost Approach, nor back into the numbers. A serious and valid effort to do it right will give you insights you cannot get with a single approach to value.
