Then you get down the rabbit hole of integrating platforms and automating your workflows which takes a lot of massaging and some technical skill. 

A $10,000,000 property is inherently more complicated, needs a multiple of different skills to operate, has financing infinitely more complex than the $100,000 property.

It’s currently mostly passive income even though he has the skill for it.

Quote from @Josh Kinnebrew: What are your skills? 

Here’s a blog on investment analysis that I recently wrote if you’re interested. https://www.biggerpockets.com/blog/real-estate-investment-analysis-for-any-asset-classBeing a good developer requires you to be good at at least one of these things: money or equity network, construction knowledge, architectural design experience, project management skills, and a broad network.

Do you have any specialized skills or knowledge that will give you an advantage?

There's little opportunity for you to add any value of your own (whether that's through rehab or other skills you might have).

I would also recommend all three of David's BiggerPockets books for agents, Sold, Skill, Scale.

This will teach you a lot of skills and prepare you for more complex investing in the future

Being an agent will teach you a lot of important skills like sales, negotiating, marketing, and more.
