Working in RE is one job that you actually have to pay to do. Here, it costs about $2,000 to take the course, do the required background check, take the test, pay your dues to the various organizations, and get your lock box key.
It can take quite awhile to get established. If you are a joiner and everyone in town knows and likes you, it will be easier.
Your schedule has to be very flexible, especially in your first couple years. A few Sundays ago, I had planned a day off to hang out with hubby. But some clients called and wanted to go to open houses, so off we went.
You will have monthly expenses, these will vary by brokerage. Some places can be very expensive to work (typically franchises), some are cheaper.
You only get paid if you are selling, so it can be frustrating to write your brokerage check every month if you don't have checks coming in.
Also, we are independant contractors, so we get a 1099 at the end of the year and have to pay our own taxes. You have to be quite organized in keeping track of your mileage, expenses, receipts and such.
I am not trying to scare you, just paint a realistic picture of what you are going to be up against.
Don't let anyone tell you that you cannot do it. Market, schmarket, those willing to work hard can make it in any market, the weak are leaving the business. And there is nothing like the look on people's faces when they have found "the" house, or the joy at the signing table after you have helped someone buy their dream.
Good luck to you in whatever you decide.
