Expert Insights
Smart analysis for your renovation budget
The 30% Rule
Never spend more than 30% of your home's current value on a single renovation. This protects your investment and prevents over-improving for the neighborhood.
Hidden Cost Buffer
Add 15-20% contingency for unforeseen issues (water damage, outdated wiring, asbestos). Older homes (pre-1980) may need 25% contingency.
ROI by Project
Kitchens and bathrooms typically return 50-75% of cost. Exterior improvements (siding, roofing) return 60-80%. Swimming pools often return less than 50%.
Calculation Methodology
Base Cost = Area x Cost per Sq Ft (by room type and finish level)
Location Adjustment = Base Cost x Location Factor
Demolition = Area x $3-$8/sq ft (if selected)
Labor = Adjusted Cost x 0.55
Materials = Adjusted Cost x 0.45
