My DH is the sales manager of a large office of a successful independent company in our area. He has been in real estate for probably 20 years. I have knwon him for 18 of those years.
Some things I have learned over the years:
~Everybody wants to be a realtor during a good market, because they see realtors pulling down big bucks for seemingly a little work. Right now in our area, the market has been wild, with homes selling for ridiculously high amounts of $$, so evrybody wants in.
~In a slow market, being a realtor can be a very hard job, very-time consuming, with a small yield.
~The people who seem to do best at it overall are the ones who make it a career. Sure, you can hit big if it's a hot market, but once the market cools down, the thing that is going to keep you afloat is the client base you've built and how you have served them.
~There are many new rules, regs, and laws governing real estate, so it is nearly impossible to do it part-time and do it well. There's just too much to keep track of and too many changes. If you don't feel you want to devote full-time to it, then it's probaly best, if you get your license, to work on a referral basis.
When I met DH, the real estate market in our area had just been through a high and was in "crash" mode. DH stuck it out, and built a good reputation and a good client base. He didn't necessarily earn thousands of dollars for those first few years of our marriage, but he served his clients well, acted with integrity, and had a good reputation. But there were some lean years financially, even though he busted his butt working tons of hours. But part of the drawback of real estate is that your income is directly affected by the market and what it's doing. You could be the best realtor in the world, and if the market is slow, you're either going to have to bust your butt to keep a certain income or your income will drop.
DH loves mhis job. He has loved helping people find a "home" as oppposed to a house, he has helped many lower income families be able to buy a home because he was willing to go the extra mile to research unusual loan options etc for them. Thse don't make him the tons of money people think realtors make, but they do give him a good deal of satisfaction.
Best of luck with your decision.
