## Observations

- **Manhattan outweighs every other borough combined** on assessed value in this pull — $92.5B across top 500 MN lots vs $50.3B across the other four boroughs' top 200 each.
- **Queens has the highest *average* top-lot assessment** at $277.7M — skewed by a single $8.5B outlier (likely LaGuardia or JFK airport land). Manhattan's average is $198.9M, Brooklyn $118.2M, Bronx $65.0M, Staten Island $26.7M.
- **Midtown/Hudson Yards density**: Manhattan ZIP `10019` leads with 60 high-value lots — this is Midtown West / Hudson Yards / Columbus Circle.
- **Downtown Brooklyn / Fort Greene**: `11201` leads Brooklyn with 39 lots — consistent with the commercial office conversion wave there.
- **Dominant building class citywide**: `O4` (office, 11+ stories) in Manhattan, shifting to `RM`/`D`-series (condos / large apartment buildings) in outer boroughs.
