So Denis-My point is that while the AI recognizes that the SCA approach may include some of the same techniques as the income approach, if one were to use the same analytical technique in both approaches, then can one really ethically hold out that appraisal report as utilizing both the income and SCA approaches? To me that might be mis-leading to a client. Just because the other more traditional anlalytical methods recognized by the AI may be weaker in terms of the credibility of the results doesn't mean that it should habe been abandoned- does it? Isn't that the primary reason for having a reconciliation?
Look, we all know that there are things we do because it is practical and makes the most sense-but when that practicality moves us closer to the ethical/un-ethical line I would prefer to be very very careful to state exactly what I did and why I did it. To me that would mean that I would state in the report that although the SCA was provided, it relied primarily upon the capitalized income method which is most commonly used in the income approach. IF it walks like a duck and quacks like a duch-it's rprobably a duck!
By the way Denis-thanks for your patience with me on this issue.
Sandy-
First, let me make a distinction between AI, the organization, and AI course material. The AI does not decide what it will teach; the AQB decides what is to be taught and what material must be covered and how it is covered. The AI is just one recognized education provider. I happen to think they are one of the better ones around (full disclosure: I am a member; non-designated). So, what they teach isn't something that they concocted by their lonesome; as one text book author said in a class I took, "it is the recognized method of teaching appraisal practice".
Next, I understand your concern about applying an inappropriate analysis technique. I'm against that too! :new_smile-l: Where we differ is what constitutes
inappropriate. Many appraisers (myself included) would have no problem adjusting a unit of comparison (in the SCA) by the cost-difference
if that is how the market reacted. I'd cite this as the reason and cost as my basis- that adds credibility to my report as I'm detailing my analysis and rationale. What you and I are discussing is if that same process can be applied to the SCA if it is an income measurement? My answer is yes.
When an appraiser makes an adjustment on the SCA grid, she or he is doing one of two things:
A. Attempting to mimic how the market reacts to those differences.
B. Attempting to predict how the market would react to those differences.
Sometimes, I cannot tell you why the market reacts the way it does; I can just show (based on historical data) that it does. A good example of this would be the appeal of a certain type of house-design; perhaps California Craftsman command a superior price in one of my markets because of the perceived appeal. About as good as I can get with that is to measure how (via paired/matched sales) what the reactions have been in the past. I cannot quantify "appeal" any further than its historical trend (selling at a premium); and, within that premium, there is probably going to be a range. What defines the difference within that range? I simply do not know; there is no credible way for me to figure that out (as a rule). And, I probably don't need to figure it out; it just may be within that buyer pool, individual tastes account for a 5% range of premium to Craftsman homes. So be it. In this case I can only show how the market reacts and I cannot explain it quantitatively other than to say there is a premium awarded to Craftsman, and based on history, it ranges between X and Y.
However, what if I can not only determine how the market reacts but why it reacts? What does that do to my analysis? In my opinion, it improves the credibility and allows the reader the ability to better interpret and judge my results.
We are back to trying to figure out why a fourplex sells for more when it is near the lake. These are non-owner properties (my given), so there is no owner-appeal premium. However, what we do notice is that the rents are higher. When we do a little analysis, we see that their is a correlation between rents, the lake, and higher values. Our matched-pair analysis shows that there is a difference.
But it is our income analysis that shows what the difference is based on. We now not only know how the market reacts but why the market reacts as it does.
This is powerful information. We can conclude (reasonably so) that for non-owner occupants, the location difference is dependent on rental differences and the value of the location difference can be directly measured by the difference in rents. We can also take this rule and test it against other properties. What we may find is this:
1. A few anomalies.
2. Some locations that we subjectively thought would be better appear to have no rent difference (and consequently no added value).
3. Some locations that we subjectively thought would be better do appear to have rent differences.
With this information, we now have an argument to make or not to make a location adjustment
even if it appears subjectively to be superior. In the real world this is a good thing to know; if I get questioned by a UW why I did not make an adjustment for a fourplex on what appears to be a busy street, I can show that there is no market premium or discount for those locations based on the rent. I've supported my non-adjustment in the SCA by means of income analysis!
In summary, I say this: On the basic level, the adjustments in the SCA grid are designed to reflect how the market would or will react to differences in units of comparison. I think we can all agree.
And, paired sales analysis could show the differences without the benefit of anything else. If, however, I cannot only determine how the market reacts but why it reacts, I've just improved my analysis of the subject and my ability to analyze other, similar properties. And if the "why" of how the market reacts happens to be cost or income, I'm going to explain that in my analysis and use cost or income as a basis of my adjustments in the SCA.
But, that's me!! :new_smile-l:
And, Sandy, just because that's what I believe doesn't mean it is right. (and don't worry, if it isn't, I'll be targeted by some of the bigger guns on this forum! :laugh: ).
One last thing: I want to second Greg B's recommendation of accumulating an appraisal library. I've noticed that many of the top-notch appraisers that contribute to this forum reference in their posts the various texts they have read and reviewed. Their level of conversation on these topics is several grades higher than mine because of their professional research. And, yes, I've treated myself to an early Xmas gift and have purchased a number of appraisal books to read. If one is really committed to becoming a professional, then this is a step in that direction.
