A buyer's agent is most commonly compensated through a commission that is a percentage of the final sale price of the property. This commission is typically paid by the seller's agent or broker as part of the overall transaction. When a property is sold, the seller agrees to pay a commission, which is then split between the seller's agent and the buyer's agent. The buyer's agent's share compensates them for their services in helping the buyer find suitable properties, negotiate offers, and guide them through the purchasing process. This arrangement aligns the agent's incentives with successfully closing the sale, ensuring they are motivated to assist the buyer effectively throughout the transaction.
