21 Unit Deal w/ SDIRA and Joint Venture

[Jermaine Williams]

I recently transferred my Traditional IRA to a SD IRA Custodian. I haven't invested with it yet and this would be my first deal under IRA. I have an opportunity to go into a J/V on a 21 Unit apartment deal. The numbers are great, the deal is great, and business partner has great terms on the financing through his solid bank relationships. My 50% investment into property would be 50% of down payment for the Mortgage. I'm looking for clarity and feedback in the following areas and I know Custodian can answer some but would appreciate the thoughts of the BP community:

-Do I need a LLC for this?

-How to form the J/V agreement to protect myself and IRA from any disqualified actions? (such as my involvement in the management of the property)

-Has anyone done something similar and what was your strategy.
