Homeowners often invest in renovations to boost property value, but not all updates provide a return on investment. Some of the most regretted home updates include excessive landscaping, swimming pools, solar panels, wall-to-wall carpeting, and removing bedrooms or garages. High-end finishes in modest homes can also reduce resale appeal. The key is to balance personal enjoyment with smart financial decisions, ensuring renovations align with neighborhood standards and potential buyer preferences.
