Self directing IRA money using QRP- Qualified Retirement plan

[Hament Raju Mahajan]

Currently I use Self Directed IRA custodians (Pensco and others) to be able to use my IRA funds for investment in Secured Notes. At times it becomes a time consuming effort to deploy funds to a deal.

I am setting up a QRP where the plan to be attached to my LLC and I could check book control control the IRA funds .

Would like to get comments from some one who has done QRP or know about it. Setting up QRP makes all the sense with the control one has and it seems cheaper to as compared to having a independent IRA custodian , what is the down side to it?
