Final answer:
In most real estate transactions, a special agent relationship is used between the buyer and seller.
Step-by-step explanation:
In most real estate transactions involving a buyer and seller, the type of agency that is commonly used is a special agent relationship. A special agent is an agent who is specifically authorized to perform a particular act or transaction on behalf of the principal, in this case, the buyer or the seller.
This type of agency is different from a general agent relationship, which involves a broader authority granted to the agent to handle multiple transactions or ongoing business for the principal.
For example, if a buyer hires a real estate agent to represent them in purchasing a property, the agent acts as a special agent for that specific transaction. They have the authority to negotiate terms, submit offers, and handle the paperwork on behalf of the buyer.
