SDIRA Disqualified Person

[Ron Read]

I'm looking to purchase a piece of single-tenant commercial real-estate in my SD-IRA. The single tenant is a business which myself and my wife own a silent 1/3 stake in. Our partners are unrelated third-parties whom control the other 2/3, and manage the business.

Is the business a disqualified person?

Follow-up:  If the answer is no, and at some point in the future an immediate member of my family ends up working for the business as a non-managing employee, does that change things?
