Bellevue / Kirkland (Eastside) · CONDO (long-term rental) · Built 2014 · 1700 sqft

For this fixture, the engine used 53.1% land allocation from source: statistical_premium_floor. This means the engine's component-bottom-up reconstruction cost exceeded 2.0× the implied depreciable basis after subtracting land, the premium land floor was applied to keep the study within audit-defensible territory. This is common for resort-tier properties where land scarcity premiums dominate the purchase price.
The engine computed a reconciliation factor (rf_raw) of 1.6367 (C band). Geographic factor: 1.1 (state resolver).
