There are two answers to this question that vary differently.
As Client
If you are a client of a real estate agent, it could be one deal or it could be a lifetime of business. At Berkshire Hathaway HomeServices our motto is Forever Agent. This motto is a great standard for our agents to make real connections with clients. Trust is a major factor when buying or selling a home so having trust in the agent to protect you in your deal produces better results. Our agents strive to be there for all of our clients needs at every stage of their lives whether it’s a first time homebuyer or someone looking for their vacation home in the Adirondacks.
Job
As a job, when an agent has passed their test they can stay an agent as long as they would like. In New York agents are required to take education course every two years as well as pay fees to continue practicing.
