In the P&C world, you'll find strings attached with every agency opportunity. With Farmers (and others), it is a loan, that is forgiven if you meet basic performance requirements. If you don't meet the requirements, you'll be bankrupt from not making any money anyway
In P&C, there is no starting out on your own as a 'newbie' and then switching. Well, you can, but you would be foolish. If you want to see if it's a career path for you, work for an agent first, then decide.
This business is setup all on residuals from renewals, unlike health and most life, where there is a larger upfront commission, and lower renewals, P&C requires you to get a big bulk of your $$$$ from renewals. If you start in one direction, then switch, you'll lose all of the work you have done up to that point in growing a book of business. None of the big companies are going to let you bring your book of business with you.
That said, it's almost impossible to start out on your own as a fully independent agent and be successful. It's sort of like trying to open your own hamburger stand, it might work, but having a McDonalds franchise almost guarantees success. Is this because McDonalds has the best burger? no. Is it because they have the best prices? No. It's simply because they have one of the best business systems in the market, and if you follow the system, you'll be successful. Same goes in many cases for being a captive agent. You're buying into the successful system.
Whether you want State Farm, Farmers, Allstate, AAA or McDonalds, I can point out websites similar to the ones mentioned. It isn't the fact that companies have problems you have to worry about (if you do, give up now), it's how they address the problems that is really the issue. I can safely say that I have confidence in all of the above mentioned companies to do the right thing.
Call a few agents in your town. Tell them your thinking of becoming an agent, and want an 'inside' view. Most will gladly talk to you, good and bad, about their companies, what makes it work for them, what they wish was different. You may even get a job offer from one of the agents out of the conversations.
If you want, PM me, and I'll give you my phone number. I can give you the inside scoop on a lot of the different companies contracts, at least as of a few years ago.
