I chose a large brokerage to start with for the excellent training. Coldwell Banker took a lot of % of commission but did not charge monthly fees. I moved to Keller Williams shortly after for a more manage-able commission split but I did incur hefty monthly fees. About five years in (well trained and en route to obtaining my brokers license) I moved to a flat rate broker (www.REeBroker.com) in California and I am delighted with the results.
I would go with a broker that you believe will teach and train you well. Ask for client referrals, see how your "new" office manages clients and client satisfaction. Go someplace where things are being done right.
The right answer could also relate to how you thrive. My brother went to a small private college with under a dozen students per class. I went to a large university with 800 students per class. We both thrived, very differently. So, discern where you thrive.
Also if you do not have the capital for about six months of self-employment with monthly fees, you may have to self-train. You could go to a small or flat rate brokerage with no fees and mentor under another agent. When I got my first listing, I asked an advanced Coldwell Banker agent to shadow with me. I gave her a part of the commission, she went with me and took the listing, and I did all of the marketing. When we received an offer, she sat with my clients and I and we accepted it with her assistance on the contract.
Unfortunately, your license doesn't really teach you how to navigate the contracts. You'll need classes for that.
The main piece of advice I can give you is this: attract good clients, work for good people you like. Do not accept opportunities to work with people who make you feel uncomfortable or bad. The main reason young agents don't stay in the biz is because they didn't like their clients. So, choose very good clients. Work hard for your clients.
And then get training in the way that you can best afford it. This can be either a monthly fee with a strong company; or a percentage of a transaction with an advanced realtor you admire and trust. There are national coaching programs, too, but I recommend you go with a local expert for your progress so that you can learn the rules and contactual particulars in your community.
