first unit sold

The first unit of a structure is sold, whether before, during, or after construction.

Sale of the first unit of a structure occurs whenever ownership of an individual segment within that structure is transferred to another party for the first time, whether it happens before, during, or after the construction phase. Pre-sales count for this event as much as regular sales.

The event concerns the first sale of an individual unit within the structure. It is separate from the first rental, the first move-in, and the start of the building's operational use.

A pre-sale is included even when construction has not begun or is unfinished. Physical completion of the unit is not a prerequisite for recording the first sale.
