Would that type of framework work?

I hope that framework helps you!

The basic framework will outline any separate property and any community property.

I'm familiar with this type of framework.

But its nice to see that the general frame work could work.

Understanding the general framework and options upfront is smart....then you of course navigate and learn more as you're approaching an actual, live deal.

Am I in the right paths and with clear framework based on what BRRRR strategy all about?

If you are putting the investors together and taking fees, etc, you are syndicating and the same legal framework that applies to the sponsor buying the real estate applies to you. 

It all has to do with attitude and approach.The IRS rules themselves are a pretty basic framework that is easy to operate within as long as you stop and ask questions of a qualified professional before taking action.BTW, there are about 4 dozen providers of self-directed plan services that outperform the company you mentioned. 

Employment status, amount of funds, geography, age, investment strategy, and a variety of other factors will inform your decision.A checkbook plan in either the IRA or 401(k) framework will generally provide advantages over the services of a 3rd party custodian.
