Sale history and market context

MakeMe Estimate: $869K (estimated market value), with a likely range of $609K to $1.1M (half of recent verified sales in this segment landed inside that range). Based on 4 verified arm's-length comparable sales (through 2026-06-01). The county roll carries a nominal improvement value for this parcel, so the estimate leans on comparable sales and the county-confirmed building area rather than the county land and improvement split. Not an appraisal. How this estimate works.

lower confidence: 1 comparable sale within 3 miles; nearest 1 mi. This property type carries wider measured error; treat the estimate as a starting point.

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.
