Final answer:
Overimprovement occurs when someone spends money to improve a property beyond the point where the improvements add value to the property.
Step-by-step explanation:
Overimprovement occurs when someone spends money to improve a property beyond the point where the improvements add value to the property. In other words, the additional money spent on the improvements does not yield a proportional increase in the property's value.
For example, let's say someone invests $50,000 in renovating their home with high-end fixtures and finishes, but the market value of similar homes in the area does not increase by the same amount. This would be considered overimprovement.
