💡 Pro Tips from Real Experience

DIY vs Tradesperson: Use the DIY toggle for jobs you'll do yourself - it only charges for materials, not your time. This gives realistic costs for hands-on developers.

Always add contingency: I've never had a renovation come in under budget. 10-15% contingency is realistic for most projects.

Get multiple quotes: Prices can vary by 50% or more between contractors. Always get at least 3 quotes.

Plan for delays: Renovations always take longer than expected. Factor in 20-30% extra time.
