Lines and Floorplans
A line is a stack of identical residences, the same plan and views, one above another. Each line’s last sale is the cleanest comp a buyer can get.

| 02 | 3 / 3 | 1,661 | — |

Each line’s last sale joins this table when the unit-to-plan mapping loads; a “—” line is a plan whose floor placement awaits confirmation.
