Large is defined by complexity and stakeholder count as much as by dollar value. A single building with concentrated high-value machinery can be a straightforward assignment; four school campuses with a district calendar, a demolition schedule and a restoration contractor already on site is not, at any value.
What changes past that point is the constraint: not how fast property can be recorded, but whether the record holds together across several buildings, several weeks and several crews. See what makes a commercial loss a large loss.
