The Mail Preference Service (MPS) is a consumer service sponsored by The Direct Marketing Association (The DMA)."

However, not for the support of the sponsor or "professionals" running the show. 

@Jorge,The Rollover as Business Startup would likely be more than you are looking for, as it involves a C-Corporation and Profit Sharing plan combination.Making a new contribution to the Roth portion of a 401k each year comes from income you earn in the business that is sponsoring the Solo 401k - which is your after-tax real estate flipping activity.As you build the 401k plan, it can invest in many ways associated with real estate.Flipping houses does not disqualify a retirement plan, it is just a type of activity that comes with a tax burden since the tax-exempt entity is competing with taxpaying businesses.  

A few months ago I paid for a multi-month direct mail campaign with former BP sponsor Michael Quarles' YellowLetters.com but now my calls and emails are going unanswered.

One thinks that General Partners can't take depreciation on their carried interest (until all Limited Partner capital accounts go negative), only on actual cash contributed and the other thinks that allocating depreciation based on overall sponsor ownership (vs cash contributed) is correct.

@Jon Holdman Reg D 506(c) that came along with the Jobs Act will allow solicitation, but limits you to only Accredited investors and adds other burdens on the sponsor.

And then when your sponsor sells the underlying property after 4-8 years, you will have to pay cap gains tax.https://www.biggerpockets.com/blog/apartment-syndication-passive-income-retire-earlyhttps://www.biggerpockets.com/blog/multifamily-investors-cost-segregation-friend

I know that you are supposed to have a broker sponsor you in order to apply for the license, How do I find a broker since I’m not looking for a job within their business?

The plan of the the sponsors is to deliver maybe another 4 to 6% on closing the dst. 

I am about to take real estate license exam and looking for a sponsor, Ohio requires having a sponsor before taking the exam.
