Exemple Résolu
A residential rental property has a building value of $300,000 (excluding land) with a 27.5-year recovery period.
- Annual depreciation: $300,000 / 27.5 = $10,909.09
- Monthly depreciation: $10,909.09 / 12 = $909.09
- Over the full recovery period, the entire $300,000 building value is depreciated
