In appraisal terms, which scenario would be classified as over improvement?

• A. An improvement that costs less than the value added
• B. An improvement that is neutral in value
• C. An improvement that costs more than the value added
• D. An improvement that decreases property value

Answer: (C)

Over-improvement happens when you spend more on a renovation than the extra value it adds to the property. In appraisal terms, the value added is the increase in market value attributable to the improvement. If the cost to install the improvement exceeds the increase in value it brings, it’s considered over-improvement. For example, spending a large amount on a luxury upgrade but only raising the sale price by a smaller amount means the improvement costs more than it adds, which is exactly over-improvement. The other scenarios either add value proportionally, break even, or reduce value, but they don’t fit the definition of over-improvement.
