Well, there could be a lot of ways, but one of the easiest would be to travel to some open houses on the weekends and chat with some of the realtors holding open homes in your area. After a good conversation you could usually tell who has a pulse on your local market. After doing that set up an appointment and interview the agent for the job. One agent that I know works and lives the San Bruno market is Dave Tapper 415-370-7195. He's been a top agent in San Bruno for many years. Call or google him and I think you might be impressed by his volume of San Bruno transactions.
