Coverting my Roth IRA and or 401K to Self-Directed?

[Armand P.]

Hi BP,

I'm considering converting My Roth IRA and 401k retirement accounts to self-directed so I can invest in real estate. However, I'm still employed and read that I'll need to open a IRA LLC in order to invest. Would I still reap the tax benefits with a self directed IRA?

The custodian on all my accounts is through fidelity. 
 
Thanks,

Armand
