Thanks for the compliment! I consider the 1004MC and the data at the top of page 2 of the URAR as "data to be reported", not data meaningful to me which is to be relied upon while forming my opinion of value. By the time I get around to "reporting" that data my opinion of value has already been formed & my appraisal is finished, just reporting it at that point. ± $500,000 might be a reasonable "range threshold" on a $3 million house. On a $150,000 house I would have to look at the market to see what I thought buyers might consider as suitable substitutes on the high or low end and set my range thresholds there. $100,000-$200,000 comes immediately to mind. Your mileage might vary.
