How much has this market appreciated since 2016?
The median sold price per living square foot changed from $1,235 in 2016 (n = 5) to $2,294 in 2026 YTD (n = 3), a cumulative change of +85.8%. The calculation is (YTD median sold $/SF ÷ 2016 median sold $/SF − 1) × 100. It measures the change in recorded sale medians, not the return on an individual residence. At least one endpoint has fewer than five usable sales, so the comparison is especially sensitive to the homes sold.
