I even know an attorney who got his real estate license to earn extra "vacation money" for his family.
Doing a few transactions each year doesn't require a lot of time, but it can yield a lot of extra money.
If you help someone buy/sell a $300,000 house, and your brokerage makes 3% of the commission (which is customary), that's $9,000 you get to split with your broker. That's $4,500 extra if you split it with your broker 50/50. Quite a bit of extra vacation money or whatever else you might want to use it for!
You can probably find a broker that offers more generous commission splits, or even better, find a broker that does away with commission splits altogether & just charges a flat fee (the BEST & something I recommend here).
The only requirement is you or your spouse need to get your real estate license.
And it's much easier than you...
