Which factor is NOT typically considered when assessing the contribution of an improvement to a property's value?

When evaluating how an improvement impacts a property's value, the assessment generally includes objective criteria such as construction costs, market demand for the property, and the likelihood of an increase in sales price resulting from the improvement.

Homeowner's personal preference, however, is subjective and can vary greatly from one individual to another. This preference reflects personal taste and lifestyle choices rather than measurable market factors. While a homeowner may feel that a certain improvement enhances their enjoyment of the home or its attractiveness, this does not necessarily translate into increased market value or appeal to potential buyers.

Other factors like construction costs and market demand are critical because they have direct implications for the investment's return potential and how the property aligns with the preferences of the broader market, which are far more relevant in formal property value assessments.
