Sale history and market context

MakeMe Estimate: $43.6M (estimated market value), with a likely range of $41.7M to $47.5M (half of recent verified sales in this segment landed inside that range). Based on 8 verified arm's-length comparable sales (through 2026-06-01). Not an appraisal. How this estimate works. About $352K per unit at the midpoint (124 units).

lower confidence: 1 comparable sale within 3 miles; nearest 1.8 mi. Last arm's-length sale: $50,752,000 in 2021.

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.
