Buyer's Agents Work for the Buyer and Not the Seller
Done correctly, a buyer's agent's job is to put the buyer's interests ahead of the agent's, to disclose all material facts, keep the buyer's information confidential, provide the buyer with sufficient information to purchase a home and expertly negotiate on the buyer's behalf.
Here are some of the services you can expect to get from a buyer's agent that you might not be able to obtain on your own. Apart from hearing about listings before homes are available to the public, agents can:
Provide comparable sales from the tax rolls.
Provide sales data from MLS based on map searches.
