Quote from @Aaron Beal:
My wife and I are Realtors in Washington. We do good for ourselves but I find myself having some Spare time on a weekly basis and would like to do something that might be congruent to real estate.
I know I can put more time into meeting with people and creating relationships, but I was curious if anyone else had some ideas of other things as well.
I'll dive in with my first post here. My wife is a realtor, so I know from experience that the work you are putting in now will take 30 days at a minimum before you see any returns. You have your steady income taken care of with your realtor business, so you would benefit from a quick source of income (buy and refinish old furniture to sell on fb marketplace, handyman services, flipping xyz for a profit, etc.) and a long term investment source of income (rental properties, etc.). Pretty much everything involves communicating with other people, so slip in that you're a realtor and grow that business while you're at it. Also, volunteering your time for charity always feels good even if it doesn't produce any income.
Good luck!
