lower confidence: 3 comparable sales within 3 miles; nearest 1.4 mi. This property type carries wider measured error; treat the estimate as a starting point. Comparable-sale caveat: the estimate is 56% above the $283.97/SF median of the shown comparable sales.

The shaded range is the model's measured error band; about half of verified sales in the segment land inside it. Diamonds: recorded arm's-length sales. Not an appraisal. How this estimate works.
