Not all transactions that occur between a disqualified person and the IRA will result in a prohibited transaction.  A list is provided in the tax code to ensure that taxpayers are aware of what is considered a prohibited transaction.  The tax code states that a disqualified person is considered to have engaged in a prohibited transaction with an IRA if any of the following occurs:

a sale or exchange, or leasing, of any property occurs between the IRA and a DP;
there is lending of money or other extension of credit between the IRA and DP;
there is furnishing of goods, services or facilities between the IRA and DP;
the assets are transferred to or used by or for the benefit of a DP;
any action by a DP who is a fiduciary whereby the fiduciary deals with the income or assets of the IRA in his or her own interests or from his or her own account; or
receipt of any consideration for his or her own personal account by an disqualified person who is a fiduciary from any party dealing with the plan in connection with a transaction involving the income or asset of the plan

This list is not all inclusive, you should work with a company that specializes in SDRA transactions.
