Which of the following is NOT typically included in a real estate property listing agreement?

A clause that allows the seller to only receive offers from non-foreign buyers is typically not included in a standard real estate property listing agreement because such a clause may violate fair housing laws and principles of equal opportunity in housing. Real estate listings are generally intended to attract all potential buyers without discrimination based on nationality or residency status.

In contrast, a clear description of the property being offered for sale is fundamental to accurately representing the asset and attracting interested buyers. Authorization for placing sale signs and lock boxes is also a common requirement in listing agreements, as it enables agents to effectively market the property. Additionally, a carryover clause, which secures a commission for the agent if the property is sold within a specific time frame after the listing expires, is commonly included to protect the agent's efforts during the listing period. Therefore, the presence of these elements in a listing agreement reflects standard real estate practices, while the specific clause concerning non-foreign buyers stands out as atypical and potentially discriminatory.
