Thanks as always, although I'm unsure whether I will ever be able to understand "since it is the probable event, it's not contrary to what will exist..." that caused a flashback to confusion I experienced during a Philosphy course decades ago...although I often wonder why residential lending appraisals aren't based on prospective opinions because it's the future rather than current value of a property that most affects collaterization in the long run, possibly because the accuracy would be so problematic...
The difference between EA and HC is subtle but important. The label used to identify the assumption is not the test of whether the assumption made is an EA or HC, but it is the knowledge of the reality versus the assumption, as of the effective date of valuation.
- If the assumption premises a condition that is KNOWN TO BE FALSE, as of the effective date, that is a HC.
- If the assumption premises a condition that is UNCERTAIN BUT REASONABLY PRESUMED, as of the effective date, that is a EA.
So, an assumption of completed construction as of a future date, if the future date is the effective date of valuation, is not known to be false, it is uncertain, hence it is an EA.
The nut of the difference is generally related to assignment conditions. If the appraisal is to be "as-is", HC cannot be employed because that would be "as if". There seems to be some debate as to whether an appraisal premised on an EA is an "as is" valuation. Some sources say no, some say it's "as is subject to the EA", some say it's flat out fine.
Another common error stems from the appropriate use of an EA for presumption of future events versus its inappropriate use. Let's say you're assignment is to estimate the value of a four lot subdivision that is under contract to close in 6 six weeks contingent on permit approvals, which are in process and expected to be awarded. Often reports will say that there is an EA that approvals will be in place as of closing or language to that effect. Labeling such an assumption an EA does not make it one. This is a HC unless the date of valuation is prospective as of the date of proposed approval award.
So if the lender has required an "as is" premised opinion (no HC), and will not accept a prospective value (to use an EA), the appraiser can not provide the value consistent with USPAP. This is a tough situation; because of the nuanced and esoteric nature of the jargon definitions, it's hard enough just to think this through let alone discuss the situation with a lender.
