Which criterion is NOT needed when assessing a property's highest and best use?

When assessing a property's highest and best use, the primary criteria include financial feasibility, legal permissibility, and physical possibility. Each of these elements helps to establish whether a property can be developed or used in a manner that maximizes its value based on market conditions and regulations.

Financial feasibility examines if the potential use of the property can generate the necessary financial return or income, making the investment viable. Legal permissibility ensures that the proposed use adheres to zoning laws and other regulations, confirming that the intended use is permitted. Physical possibility assesses whether the site can physically accommodate the intended development due to size, shape, location, and any existing structures.

Community impact, while an important consideration in real estate and urban planning, is not a strict criterion in the formal assessment of highest and best use. While community impact can influence a property's value and the decision-making process for its use, it is not as concrete a requirement as the other factors. Therefore, it is the aspect that is not essential when determining a property's highest and best use.
