The unending debate on whether RE agents are worth it!
I see it as similar to doing a small remodel on your house. Some people can find this painfully easy to do themselves and ridiculous to spend an additional 20%-30% on labor. For others who have zero knowledge, or skills, may find it not so simple.
Sure, you can learn how to do most of this stuff, but some people just aren't cut out for it. I think having a legal-background would be super-important, especially in more expensive market, where hustlers like to play.
