Most states require you to take to classes, one about real estate as a whole and one about your specific state. In order to become a broker (which means you have agents working under you and recieve a percentage of their sale) requires you to work as an agent for 2 -3 years and take 128 hours of brokerage classes. Mainly over saturated, most cases no benifits whatso ever, and tuff to get started, i hihgly suggest you get a job selling new consrtuction for a builder which gets you a steady income and commision in most cases. Move into commercial real estate when your feet are wet and develope land. strip malls, building etc.. its a lot easier than many think just takes time, patience, and a hell of a work eithic. But SO much moeny if done right.
And about the comment of moving to a rich neigbor hood to sell high priced homes, it is true but highly inaccurate. Bread and butter of many top brokerage firms comes from houses around 100k and under since there is a high turnover. High priced houses are tuff to come buy as they mainly go to an agent with more experience or a friend of a friend. Hope this helps. You get out of it what you put into it which makes it a great career path. And those who think its a femist job are just plain asses, they change their mind when they see the income and life style
