1st thing that’s great about getting started as a realtor is that almost everyone wants you to join their brokerage. So it’s very easy to find them. I would google all the local offices if your area and interview THEM to find which is the best one for YOU!
Awesome advice form @John Warren on knowing your goals before choosing.
Great post to look for help getting started! Yes training is important and getting a great mentor is crucial to beginning success! Some of the bigger brokerages do have fancy training programs to plug into, but for me it’s about finding a brokerage as a new agent where you can get the direct support your looking for to be successful. Real estate training now in this age is everywhere. There’s thousands of podcasts, YouTube channels, and classes you can take from other successful agent to get that as well where a smaller brokerage might not have the fancy training platform to plug into.
In my opinion the mentor is paramount because you will need someone who is going to get in the trenches with you, role play conversations with you so you are ready to talk with sellers and handle their objections about your commission price, why their house isn't a worth $20,000 than what your CMA says, and why they should choose a new young agent like you and I vs a more experienced agent that has sold 100s of homes in their career. Or take you through step by step every document you need to get signed when working with a buyer.
So I would strongly consider joining a team or brokerage with a strong support system where you wont get lost in a sea of 500 agents.
Also look for one if your interested in investing that would tailor to that as well.
Good luck would love to talk and help you get started on your journey!
