Daily I see signs that have a picture very popular Real Estate Agent. Interestingly the picture and the name on the sign represents a Real Estate team with "buyers agents", "sellers agents", "transaction coordinators", but you may not ever see the person on the sign.
The quality of the effort expended on your behalf could vary based upon the specific agent you have working with you.
Consider the alternative. The agent you know and the agent who will work directly with you to buy or sell your home or property. Your agent should know the area, know the property, provide personal attention and have your answers.
A real estate team might not provide what you want or need. So consider the alternative.
