  1. I live in Idaho, Have $340k in cash in IRA and want to set up check book control self directed IRA and buy apartment building.
    I need to see your fees, the upfront and importantly the ongoing fees.
    Time is critical, I am in the process of selecting my provider.

    On 3-15-2012, I rolled over an IRA in the amount of $50,000. to the First Trust Company of Onaga. I recently received an invoice for account fee, special asset fee and activity fee for a total of $155.12. I believe these fees to be excessive for what little Onaga does for my account. I have asked my broker to transfer my account to another bank who has lower fees.
