The key word here is “family.” The problem is what if the household is composed of three people who are unrelated, or the seller is someone who lives alone? A better approach would be to address the letter to either the “sellers” or “owners.”

When you include a picture of the buyers, you provide a means for sellers who may have a conscious or unconscious bias against a wide variety of the protected classes based upon race, color, sex, familial status, age and disability. To avoid these issues, stop using photos of your buyers on any letter to the seller.

Any reference to religion is prohibited. Rather than mentioning the kosher kitchen, a better approach is to say, “The buyers really love your upgraded kitchen, especially the two refrigerators and two dishwashers.” In other words, focus on the features, not on who will be using them.

While those who do not speak English as their first language often prefer living in areas where others speak their native language, this is exactly the basis of the Newsday investigation that showed agents often steered their clients to areas where there were “more people like them.” For example, a family from outside the U.S. may prefer selling to another family from their same country of origin. Agents must proactively avoid making any reference to the national origin of any buyer or seller.

Fair housing laws prohibit agents from making references to “familial status.” For example, a seller may be more prone to sell to a young family with their second baby on the way rather than a gay couple or someone who is single.

This question raises some interesting issues. You are not supposed to reference familial status or age, but you can legally discuss age restrictions for 55+ communities.

To avoid having issues with Fair Housing, a better approach would be to say, “My buyers are downsizing from their current 4,500 square foot home and are excited about moving into a lock-and-leave community where they can travel more.”
