I hope this give you a better insight as to how the industry works. 

I'd like to pursue sales, and for a while I thought I'd be looking in the tech industry.

In a nutshell it is a cash flow industry with high yield (6% to 11% net pretax) affordable at USD$30K to $70K on average, and most importantly services are transparent.

I've been in the construction industry since i was a teenager and thats a long time ago.

I regularly attend workshops and seminars to stay updated on industry trends and best practices.

I did a ton of research and talked to dozens of people in the insurance industry before reaching a decision.

I'm just an investor in SFR/small MF and the vineyard/wine industry near there.

As a few others have mentioned I think the 15% fee for MTR is the typical industry standard but it can depend on the area

After graduating college with a degree in both marketing and finance I transitioned to the lending side of the real estate industry.

At the time when the chemical industry discovered farmers as a huge market all sorts of herbicides and pesticides (the are banned today) were introduced, stored and disposed of basically into the ground: the farmer did not want to have stuff growing between the barn and the farmhouse anyway, so seemed like a good spot to kick that barrel over.
