Call the offices of some of the custodians that interest you and see how the phones are answered.

Quote from @Kaushik Sarkar: Hi,I am interested to talk to SDIRA custodians preferably local to the DFW Texas area to expand my investments in real estate.

Instead of a custodian/administrator, find a facilitator (i.e. a third-party administrator).

I collaborate with large custodian companies.

This money is sent to a company that acts as the custodian and makes sure all the tenants bills are paid on time.

So for anyone reading this, the difference between Titan (and Solera) vs. other national banks is that their application for a business checking account specifically asks if you are trying to set up an LLC checking account for an LLC owned by an IRA, and if you check "yes," then you have the opportunity to enter the IRA custodian's contact information and clearly identify that the IRA is the owner and that the manager of the account has 0% ownership interest of the LLC. 

I understand that you need a custodian, I understand that you can only transfer the 401(k) once you have stopped working for the employer, and I understand that once you’re 55 years old, you can start accessing your 401(k) so here are my questions…1.)

Checkbook control bypasses the custodian.   

Worst case you can transfer the money from the current custodian into Fidelity and back and forth it would just create work for you and possible wiring fees....

@Erik EstradaThe crazy part was that when I had spoken with the Self Directed IRA custodian, Equity Trust Company, they had given me a list of lenders clients had previously used.
