If I remember correctly, you’re not exactly a self-starter. I know several RE agents - they are hard workers. They are usually not employees who get told what to do, but contractors who work for themselves under the umbrella of a designated RE broker.
To sell real estate you have to be energetic & on the ball. You have to know a LOT about both selling & RE law. You have to take tests about that knowledge. Have you seen a RE contract? The one we signed when we were thinking of selling was maybe 20 pages long. Good thing we were working with a friend - we didn’t have to worry about understanding everything in the contract - we knew Larry did understand it & wouldn’t screw us over.
Unless you’ve had a major personality change, I don’t think real estate is for you.
Forgot to answer your question - RE agents do sometimes work on Sunday - if they want. Larry works sometimes on Sunday, but he goes to church first. And he’s Protestant. I used to work at a hospital, which meant working on Sundays & holidays. I was always able to make it to Mass somewhere.
