Have fidelity IRA, want to change to a self directed. need advice

[Nicholas Field]

Hi, 

I currently have a fidelity IRA (2 different ones actually) and I'm looking to buy an investment property and would like to use my IRA money. I understand I can move my money into a self directed IRA and use those funds to do it. This is correct?

What's the process for this? Where can I find a place for a self directed IRA?

If I have a personal mortgage on the property will this make a difference on using it for these purposes? 

Follow up, but separate question: Can Self directed IRAs be used for primary residence?
