The 30% rule is a guideline in real estate and renovation, often applied to kitchen and bathroom remodels. It suggests that the cost of your renovation should not exceed 30% of the home's current market value. For example, if a home is valued at $500,000, the renovation budget should be capped around $150,000 to avoid over-improving the property for the neighborhood. This rule helps homeowners maintain a good return on investment. At Lecut Construction, we advise clients in San Jose to consider this rule when planning major updates, as it ensures your project aligns with local market expectations and protects your home's resale value.
