Newbie to Self-Directed IRA

[Eric Wu]

This is my first post.   I want to learn about how to invest RE thru SDIRA.   I understand I need to set up a checkbook SDIRA.   Hoping anyone who has gone thru this process gives me a hand and get me started.    Specifically, where can I find these providers?  What are their fees?  How to get a mortgage when buying with SDIRA? etc...
