First, please do NOT think you're going to generate enough cashflow to live off of within 3-5 years. 

The goal is legitimate: due to complex tax rules, you have opportunities to game the system by selling some of your investments and intentionally generating either gains or losses.

A single property is simpler to manage, carries lower financial risk, and offers streamlined tax reporting but may generate taxable income sooner.

Does anyone have experience with how much the annual revenue might be?

The key rules are as follows:1) Syndicator MUST have significant skin in the game, including 10% of the money raised in the first deal, 8% of the second, and 3% of the third2) The only fees allowed are 5% of revenue for property / asset management, which is enough to put food on the table, but not incentivize people to just buy, buy, buy3) The only compensation is 20% of the profit (less on the first 2 deals)4) Rapid acquisition is not allowed. 5% Is minus all operating cost correct ? 

but without the whole "broadcasting" thing that you mention, I don't think I would have generated the outreach to the people of my age today who ask me for guidance on their first investment.

What this implies to the typical RE investor is obtaining significant cash flow is a big challenge right now and relying on other RE profit sources (such as a value add and not doing a value subtract) may be a more certain path of generating returns.  

OR it may be the spark needed to build out your next RE revenue strategy.  

Because it's my money, I care more (I get 92% of the revenue, PM only 8%, and PM team member near 0%), I only had my units to manage (PM team member has other owners and units), and, with humility, I am smarter and harder working than the team members assigned to my portfolio (3rd party PM has to hire at a level that makes the business model financially work for them). 

If your area is popular over Christmas, you could still get booked and with slashed prices you just lost some revenue.
