Most agents act as both buyer and listing agents. Those that sell high volume usually have teams underneath them. Too few isn't a significant issue as real estate agents work under brokers which can guide their actions. You also don't NEED a buyer agent, you can go see separate properties and purchase them without an agent. PM me if you want more info, as I am a realtor.
