I agree with the comments made, but I'd go even further and take a more mathmatical approach to the decision.
Figure out first what your NET income goal is. For example sake, let's say you want to earn a net income (before taxes and insurance) of $50,000 your first 12 months.
To net $50K, you'll probably need to generate roughly $100K in GCI (Gross Commission Income). Let's just call it $96,000 to make the math easy, and say that you'll need $8,000 per month of GCI.
You can charge whatever commission you want, but for example sake and to keep the math easy, let's say you'll earn 3% for each transaction side you complete. If that were to be the case, you'll need to close $266,667 in sales each month, or about $3,200,000 per year in production.
Again, keeping the math easy, if the average sales price in your target area is $266,000, then you need to close 1 deal a month to meet your goal. If the average sales price is $133K, you'll need to close 2 deals a month, or 24 deals a year.
Find out what the average sales price is for the area or neighborhoods you want to target, and do the math.
Now, looking at the sales activity for your small community, are there enough sales for you to meet your goals? If only 50 homes a year sell in your farm area, and there are dominant agents that take the lions share of those listings, you're probably not going to start taking 12 or 24 deals a year. You'll need a bigger pond to fish in.
Also, most new agents do better starting off focusing on buyers as much as listings. This means holding a lot of open houses to find buyers willing to work with you. Open houses cost you nothing (except time) but provide you a low budget way to start getting your name out in the neighborhood on your open house signs.
If you go with a company that has a lot of listings in the area you wish to work, you'll have plenty of good listings within your company at which to hold open houses.
Any Broker worth their salt will run through these numbers with you, and a more detailed version of what I've summarized. They want you to succeed. They know the sales data.
Don't get your license and go into business without a business plans that sets specific goals based on actual sales data for your area. This is the mistake most agents make and it's why most wash out the first or second year. Buy the book
Millionaire Real Estate Agent and read it cover to cover. You'll be WAY ahead of the game if you do that.
Finally, if Keller Williams is strong in your area, you would do well to seriously consider going with them. They have the best training out there for new agents, in my opinion. Feel free to PM me if you want to know more about the KW system and culture.
Good Luck!
