@Jonathan Duhon I don't know that there is "a champion of networking", and I feel like anyone who would boast this title is blowing smoke for self promotion. 

They are ultra profitable.   

Management companies don't seem ultra profitable, and cash flow seems like a real problem in the early stages.Would this split be different if I decided to hire a management company rather than do it myself?

Then judge technical proficiency as opposed to boasting or marketing hipe.

The above article is a helpful reminder to step away from the busyness and ultra speed multitasking to give your mind some time to think strategically.  

For ultra wealthy folks, they bought mansion in area like Atherton and Los Gatos since 90/early 2000.

Behr Ultra premium plus worked great when I used it - one light grey coat covered a deep red.

There's also a craigslist ad going around about joining an REI team, of course they're boasting 10k a mo. potential which concerns me as possibly being a scam, but if I could learn a thing or two from it and possibly network in the process maybe it would be worth looking at?

Maybe in an ultra-hot market you could just sell outright (flip) and collect the extra cash but now you're looking at significant tax implications and there's no long term residual income.  

Football players or any ultra high income earners are targeted because they are seen as less financially savvy and more importantly they have MONEY.
