The 30% rule for home renovation suggests you shouldn't spend more than 30% of your home's current market value on a renovation project to avoid overspending and protect your investment, ensuring it aligns with property value and neighborhood standards for a good return on investment (ROI). For example, a $400,000 home would have a maximum renovation budget of $120,000 (30% of $400k). This guideline helps prevent overcapitalization and financial strain, but exceptions exist for "forever homes" or luxury properties where lifestyle or unique features outweigh strict ROI.
