Which of the following is not considered "valuable consideration"?

Valuable consideration in the context of real estate transactions refers to something of value that is exchanged between parties to form a binding contract. Generally, this can include money, property, or services, which have a measurable economic value.

In the given choices, "Love and Affection" is not considered valuable consideration in legal and real estate terms. While these sentiments are meaningful, they lack the tangible economic value that is required for consideration in a contract. In contrast, the other options—percentages of the purchase price or a specific dollar amount—represent quantifiable financial commitments, thus qualifying as valuable consideration. Even though $1 may seem minimal, it is still a legitimate form of consideration, as it indicates an intention to create a contractual relationship.

Therefore, the correct answer highlights the distinction between genuine economic value and intangible sentiments, clarifying why "Love and Affection" does not meet the criteria for valuable consideration in real estate transactions.
