Which phrase would NOT be considered discriminatory in real estate advertising?

The phrase "Families welcome" is considered non-discriminatory in real estate advertising because it conveys an inclusive message that invites families to reside in a property or community. It does not exclude any specific group of people based on race, color, religion, sex, handicap, familial status, or national origin, which are protected classes under the Fair Housing Act. This phrase promotes diversity and reflects a welcoming attitude towards individuals or families looking for a place to live.

In contrast, other phrases listed illustrate elements of discrimination. "No children allowed" explicitly excludes families with children, which is a violation of fair housing laws. "Single apartments available" could suggest limitations based on family status, and depending on how it is presented, may indirectly imply preferences against families or individuals with children. "Low-income housing" is a descriptive term for certain properties, but it may also be interpreted in ways that inadvertently discriminate based on economic status, thereby potentially indicating biases in housing options.
