The promotor has a set fee or charge in order to pay for his hard work and is clearly set in the beginning or the promotor will be in on the deal which will be his payment of setting it up, (skin in the game, his money involved). tax reasons about capital gain?

Anyway, the creator and promotor of this strategy had to endure years in tax court, but eventually it resulted in a somewhat favorable outcome. 

I am a big self-promotor.

the only one making any real money here is the promotor charging you for this rehashed information.  

You can then sell-on the property prior to completion.Prominent builders/promotors will also offer bank-guaranteed stage payments thus protecting your investment in the event of breach of contract.

Tax lien investing can be profitable but it is nowhere as easy or risk free as the promotors would have you think. 

Then it just became a natural progression at about 30 I decided to hang up my Brokerage hat and took my first semi job with a syndicator  ( now a PPM promotor or crowdfunder) in San Mateo I did site acquisition and management of the entitlement process for subdivisions from Nevada co. to El dorado and Sac... along with North bay area.Then I found hard money lending and mentored with a gentlemen that had one of the most successful HML companies in Alameda county and he has no succession plan an no heirs..

Keep in mind here that it is not as easy or risk free as promotors would like you to think. 

There're few folks here that implicitly promoting syndication/SPV/investment group or club and such LOL , sometimes one or two folks that implicitly promoting syndication/SPV or everything in between , they need to ethically put explicit disclaimer such as "I am receiving commission and compensation from syndication business as I'm the co-promotor/co-syndication of such and such"...just like when someone promoting Ohio real estate heavily we know they're Ohio realtors so it's ethically understandable LOL

Account Closed  its really amazing when you do well for investors don't take the attitude that the investor should make a little while us promotors make the lion share ,, how much money you can raise.this is one of the HUGE mistakes and disconnects I see on BP all these newbies looking for that 8 to 10% private investor..
