Flipping houses regularly in such a plan does incur tax known as UBIT since the tax exempt entity is conducting a business and competing with taxpaying businesses as opposed to just making passive investments.  

Opportunity Zones can be used to minimize tax payments or even reduce to zero.Opportunity Zones were created under the TCJA to; Allow U.S. investors to defer all 2018 capital gains for eight years if the profits are reinvested and held in an Opportunity ZoneLower the amount of capital gains taxes resulting from the sale of a capital asset by 10% or 15% if the proceeds therefrom are held for five or seven years, respectively, in an Opportunity Zone project.Provide for a full exemption from capital gains taxes on all future capital gains on the invested funds if an investment is held for ten years following investment.

Loans can be processed from the Solo 401k at 50% of the account balance but cannot exceed $50,000.Also, Roth 401k contributions are allowable regardless of income level, thereby affording taxpayers, who would not otherwise be eligible, to take advantage of the Roth component.
