Well then, we have a serious problem, don't we? Since COVID, I have either reviewed or seen close to 100 appraisals. Not a single one not one had the market increasing. I'm being dead serious here, not one. Every market of mine has seen appreciation levels of 15-25% annually. Checking stable when the evidence clearly shows the opposite is happening can have severe ramifications on the valuation of the property, especially in a market with few comparable sales. Lenders make different types of loans depending on market conditions.
Suppose you have to go back 6-12 months(or more) for comps in a market experiencing that level of appreciation. In that case, you will severely undervalue the subject property because you are supposed to bring those comps up to the valuation date. If, on the one hand, the appraiser knows the market is increasing and deliberately states that it is not well, they have violated the ethics rule. If, on the other hand, the appraiser does not know how to complete a market analysis (which is the meat and potatoes of any assignment), they have violated the competency rule. Either way, appraisers who do this work show neither ethics nor competency. Just wait until the opposite happens and the market crashes. It's one reason USPAP should be eliminated from secondary market work. Let the GSEs and FHA handle it. It's their certifications, their forms, and their rules.
By the way, I don't blame appraisers as much as I blame TAF and their horrid Qualifying education for this mess. You can also throw in the just as bad "Continuing Education," which is another way to fleece appraisers of money. And yes, I know what you'll say before saying it, "TAF sets the minimum standards blah, blah, blah. They own all of it, time to take responsibility and stop shifting blame around.
