If it doesn't work out If you are not happy with an agent, thank them for their time and choose another. Repeat the process to find an agent and try again. Most agents are professional and service-oriented, so you shouldn't encounter much bad luck. When you do, don't hesitate to end it and move on. If all goes well If you are happy with the agent, make a commitment to stay with him or her.
Agents work most diligently when they know they have a loyal client.
You will not do yourself any favors by jumping indiscriminately from agent to agent. The worst thing you can do is to call listing agents for each and every advertised home. It is never to your advantage to deal directly with the listing agent. In some jurisdictions, agents can ask you to sign them on as your buying agent. This means that they are legally obligated to act on your behalf instead of the seller's.
