In this market, I’d say you do.
When money was freer and people were buying and selling homes as quickly as they could, all kinds of people got into the realty business. But not all of them have the experience to guide you through the maze that is real estate today.
A good agent can show you houses in your price range and explain all of your financing options. Choose an agent with a track record of selling homes, who knows the neighborhoods you’d like to live in, and who can help you figure out how much the home is worth and how much you can afford.
Ask friends and neighbors for referrals, and interview several agents before signing on with one.
