Which of the following is an example of discrimination in real estate?

Discrimination in real estate refers to unfair treatment of individuals based on certain protected characteristics, such as race, color, religion, sex, national origin, familial status, or disability, as outlined in fair housing laws. Refusing to show a property to someone based on their race is a direct violation of these laws, exemplifying discrimination.

This action not only denies equal opportunity in housing but also reflects a prejudiced mindset that can perpetuate systemic inequalities within the housing market. Fair housing laws are designed to ensure that everyone has access to housing options without facing bias or exclusion based on their identity.

The other scenarios do not directly involve discrimination against individuals based on protected characteristics: adjusting rental prices based on income could be a reflection of market conditions rather than discrimination; offering different commission rates to agents does not pertain to characteristics protected by housing laws; and adjusting property taxes based on location is often related to zoning and local government policies rather than discriminatory practices. Thus, the scenario that clearly illustrates discrimination is the refusal to show a property based on race.
