What distinguishes a buyer's agent from a seller's agent?

The correct choice identifies the primary function of a buyer's agent, which is to represent the interests of the buyer in a real estate transaction. This role involves advocating for the buyer's needs, preferences, and objectives, such as finding suitable properties, negotiating offers, and ensuring the buyer understands the market conditions. The buyer's agent works exclusively on behalf of the buyer, striving to secure the best possible deal and protecting the buyer's rights throughout the purchasing process.

In contrast, the other options do not correctly capture the defining aspects of a buyer's agent. For instance, stating that a buyer's agent represents the seller's interests fundamentally misrepresents the role, as it is a conflict of interest. A seller's agent, meanwhile, typically focuses on meeting the seller's needs, which shows the clear distinction between their responsibilities. The notion that a seller's agent only deals with commercial properties does not reflect the breadth of real estate practice, as seller's agents can work in residential markets as well. Lastly, while financing can be a part of the overall home-buying process, the role of a seller's agent does not solely revolve around assisting in property financing, which further differentiates their functions. Understanding these distinctions is crucial for navigating real estate transactions effectively.
