ummmm...Frederick...
I am all with David and of course George on this one. Market value is all about what it is worth
as of the effective date for most appraisal assignments. You find this by analyzing the MARKET, not just a single prior sale of a subject.
Of course you SHOULD analyze and comment on subject prior sales. More comment needed if the prior sale(s) seem out of line, less if in keeping with neighborhood/area trends.
~ prior sale of subject appeared to be within market norms.
OR
~
prior sale of subject date 2months ago appears to be well under/over market norms because~~whatever you found out - or even what you were unable to find out~~
...distress sale (relocation, repo, damaged by fire flood.... etc etc.)
...non-arms length transaction (family)
...factory closing (factory now reopened)
... had caught fire and was subsequently substantially remodeled.
...for unknown reasons sale appears to have closed at well above market!
lots of reasons why a subject or a comp prior sale may have occurred that spiked high or low compared to the rest of the sales in the area. Like George if I know about listings I comment on those also.
Your analysis of the SUBJECT present/market value had best be based more on what the subject is worth as of the effective date than on any past activity.
If past activity indicates 'some other factors' at play they would best be discovered and explained, but not CONSIDERED in present value unless they do in fact relate to present value!
Frederick: it is refreshing to note that some of us can find and quote USPAP and Fannie , but you gotta remember that the report is based more on your scope and certifications... what is says your mission was and how you reported it!
Doing high dollar homes where one new to town poorly advised person got stupid and paid way over market for a home does NOT a
market make!!! No matter HOW much every realtor in the are wants you to believe it
Take a deep breath David. breathe. Breathe... it is damn hard to do that when you are biting your tongue, yah?!?!
