Hi, I was doing an review for a purchase. The purchase price is $560,000 and the appraisal has an estimate value of $1,200,000. The property has been on the market for 980 days. I did an research and found out that the subject property is a "nonconfoming" property and the original appraisal stated it is "legal" zoning and all the comparables in the original appraisal report were all "legal" zoning properties. I disagree with the value in the original report but I wasn't able to provide comparables to support my opinion of value since there has been no sales of similar condition properties in the neighborhood. I gave a value of $560,000 as my opinion of value in the review and it was based on the market reaction to the subject property since it was listed for almost 3 years and the value was not recognized by the market until recently. Am I did the right thing? Or is there any other way to do this? I appreciate all comments.
