Value by Floor & LineAverage estimated price per square foot by floor range, using unit numbers to infer floors. Higher floors usually price higher — the gap shows how much the view is worth here.
Unit lines by $/ft²Condo units stacked vertically share a unit line — the last digits of the unit number (like 05 in 1205, 1305, 1405). Lines share a layout and exposure, so comparing estimated $/ft² by line shows which position in the building commands a premium.
