How can an arm's length transaction best be defined?

An arm's length transaction is best defined as a transaction in which the buyers and sellers act independently and in their own self-interest, ensuring that the terms of the agreement are fair and reflective of market conditions. This type of transaction typically occurs between parties who have no pre-existing relationship, preventing any undue influence or favoritism that could affect the transaction price.

In the context of real estate and property valuation, an arm's length transaction is critical because it provides a reliable standard for determining market value. When assessing the value of a property, transactions that are conducted at market value are essential indicators, as they reflect the true worth of the property under normal market conditions. This stands in contrast to other sales types, such as quick sales or transactions influenced by special relationships, which may not yield an accurate representation of the property’s market value.

Understanding the distinction between an arm's length transaction and other types helps clarify the importance of market conditions and fairness in property assessments, guiding professionals in making informed judgments regarding valuations.
