Let me begin by saying that both approaches have equal merit, but I am an individual agent myself. As in everything in life, there are pluses and minuses to every approach. I'll explain how I work and also what you might expect from a team agent as well.
First of all, as an individual agent, I still have a support team. In fact, I have several support people within my office that are ready and willing to assist at a moment's notice. HOWEVER, in most instances you will always speak directly with me and I will handle most aspects of your transaction personally.
It is my belief that only the most organized and customer-service oriented agents have the skill and expertise to manage millions of dollars in sales as an individual agent. I am extremely organized and efficient and prefer a hands-on approach to my clients and my business. I feel like I can offer more personalized one-on-one service as an individual agent and prefer not to have an unlicensed person handle any part of your transaction.
Team agents have other licensed and unlicensed personnel working for (or with) them in specific functions, such as buyer brokerage, transaction coordination, photographer, etc. These teams of real estate professionals typically assist a greater number of buyers and sellers at one time than an individual agent. Teams may be small (two individuals) or large (5 or more individuals). If you have a question, you may not always be able to speak with "your" agent, but you will be able to reach someone who can assist you. It is simply a different approach to customer service.
As a home buyer or seller, it is important for you to decide whether or not you prefer to work with an individual agent or a team agent...if you even have a preference! Some people prefer the individual attention they receive from an individual agent while others enjoy the ease of access that a team provides. Neither approach is "right" or "wrong" and both offer tremendous advantages to the client.
It is a personal preference, but knowing which you prefer will help make your transaction smoother. Either way, your real estate agent will be on your team...and that is what is most important!
