Many homeowners invest in renovations expecting a high return, but some home updates fail to add value when selling. To avoid costly mistakes, homeowners should not overspend relative to their neighborhood, take on unnecessary debt, or invest in highly customized features. Updates such as luxury landscaping, extravagant pools, solar panels, sunrooms, and smart home lighting may not recoup their costs. Other potential pitfalls include bold paint colors, excessive carpeting, converting rooms, or installing high-end features in modest homes. Thoughtful, balanced upgrades help homeowners maximize their return on investment while maintaining enjoyment of their space.
