Which of the following is an example of a unit of comparison in real estate?

A unit of comparison in real estate refers to a standard measurement or metric that can be used to evaluate or compare properties. The living area of a property is a clear example, as it provides a quantitative measurement that can be used to assess the size and value of residential properties. By comparing the living area of different homes, real estate professionals can determine how much space is available and how it relates to other properties in the market.

In contrast, while school districts, market trends, and location are important factors that influence property value and desirability, they do not serve as standardized metrics that allow for direct numerical comparison in the same way that living area does. School districts can affect the value but are more qualitative in nature. Market trends reflect broader economic conditions but don't quantify individual property characteristics. Similarly, location is a critical aspect of real estate valuation, but it encompasses a range of qualitative elements rather than a single unit of measurement.
