I lived in the OC for 23 years and used a lot of agents that had no skill set, and others had a great deal of skills and knew what they were doing in a short time of selling.
I have found selling real estate in a short time in Connecticut that a great broker is worth their weight in gold when they support your career and help you as much as they can as long as you are willing to go the extra miles and do the work. Its all up to you at the end of the day, what you put into it is what you get out of it = )
I would recommend checking out Coldwell Banker, they have mentors that will help you and even hold your hand through your first couple of deals.
