Joyce,
I'm not sure how we got from 'paired sales' to explaining adjustments to state investigators, but
I'll play along. My first residential class had an instructor with 30 years of experience, could
have retired, and when he got about 6 weeks into the class told us, "Everything I've told you is
appraisal theory and practice, but the reality is after you leave the property you have to go
across the street, look at the property, and figure out how your going to appraise it." So I've
always had that attitude that you really should approach the appraisal problem with an objective
view of how your going to come up with that supportable estimate of value.
Now I don't think I've read an appraisal report where I couldn't find the numbers that
made sense and the one's that I could drive a truck though, that were soft and weekly
supported. While there are probably some markets with cookie cutter houses where paired
sales is a valid, useful technique. But its not my market.
I'm always more than happy to do a narrative explanation on how I developed an adjustment.
And there's a page in the work file that has some hand drawn graphs with some average
calculations with a circle around a few numbers that were developed and used in the report
that are circled, and they clearly look like work product and not suitable to be included
in the report. They aren't precision, they are opinion.
Fortunately, I think most state examiners know by now that appraisal isn't science and the
paired sale isn't all that pairey. I get a kick out of the antique and auto shows where the
experts are opining values based on their experience and gut, and know 'about how rare'
the item is, and come up with a value or a value range. Real Estate Appraisers have a
a 100 pages of regulations accompanied with 150 pages of explanations of the regulations
intended to make us responsible for any shenanigans. So, I still see appraisal as more
art than science, with an explanation about how I got where I did, but I think appraisers
are kidding themselves if they think they are 'proving' value to the god of USPAP.
