How this is calculated: The base cost is determined by multiplying your square footage by the selected renovation level cost per square foot. Additional costs are added for specific room renovations (kitchen, bathrooms, etc.). The property type multiplier accounts for complexity, and the labor rate adjusts for regional cost variations. Finally, a contingency buffer is added to account for unexpected expenses. This is an estimate only; actual costs may vary based on materials, labor, permits, and unforeseen conditions.
