Sorry age... not trying to dump on you... just read the original post and created a lot of uncertainty. I was cutting 9 out of 10 appraisals last year when the market shifted... and it got really disheartening to say the least. My old boss and I worked on a review the other day... the original report nailed the value, but the adjustments were so ridiculous, every comp had to be regridded. His value range ran from 1.5M to 3.5M on his six comps. Low and behold, he guesses right and said 2.0M. But if he had applied the correct site adjustments based on very good market data of land sales instead of saying "site adjustments were based on X dollars per sq ft", his comps would have been money.
Good luck in retirement. Not sure how good market data can screw you on a report... would make me wonder what was possibly out there that went against your data. My question is: Would you still reconcile the same number today based on that effective date if you relooked at the data. If your gut says it's a huge push, maybe there are issues. Anything within 5% of value by "market standards" is typically agreeable. It sounds like you missed by 15-20% based on the review. Good luck.
