I think as long as you explain your reasoning, the market trend is whatever your training and experience lead you to believe it is.
Imo, if various appraisers have sound training and relevant experience, they should not come to wdely differing conclusions from looking at the same market data. They should come to somewhat equivalent conclusions.
Two opposite conclusions can not both be corrrect. One of the conclusions from the data will be credible and supportable, the other, not.
An appraisal is an opinion, and statistics can be used to support many different opinions.
It is an opinion developed from market study, and that means more than running statistics.
Thus, if a proper market study is done, which means thorough research of conditions, sales, listings and trends affecting subject market and area, the opinions should correlate to the research . Correct research can not support two opposite conclusions simultaneously. If two oppoiste conclusions are formed, it is more likely that one person did not comprehend the research or is applying the results incorrectly.
Two different appraisers can look at the same data set and arrive at different, well supported opinions of the market trend
I am not arguing this on a personal level, but on a methodology level. How can two differing opinions be both well supported AND credible?
Well supported is only one of the tests,because one can find outlier sales to "support" any opinion of value, and one can frame a statistical search in the same manner. But neither would be credible, if tested against the best substitute comps for subject or credibly developed and explained data search that might include statistics. The same for a market trend, it's either there, or not there, and can be shown through data as well as verified with inerviews and recent experience in the area.
If prices are declining and clearly shown to be declining, how can an appraiser look at the data, and form an opinion that it is not declining, and call that opinion "well supported"? What, exactly, is supporting the opinion?
If a faulty data search is the cause, or the appraiser could not differentiate between the larger market conditiions/prices and the trend effecting subject, then the appraiser mis understood or mis applied the data, and the
opinion is not well supported.
Sticking graphs or charts in a report does mean an opinion is well supported if the greater depth of research shows the true trend is not what a graph, which tends to average prices, showed.
