Is it possible to have multiple self directed IRA?

[Franky Juwana]

I'm soon will purchase a mortgage note, and for tax purposes and I think Self -direct IRA is a better choice for me and my wife. Now the question is, can an individual/couplehave multiple Self-Directed IRA? because I believe 1 account max is $5500/year and couple is $11000/year, because we dont want to wait for 2 years or more just to purchase 1 note.

    So, does anybody familiar or have similar experience that you could share for us to make a better decision, I'd call few companies too but I'd figure to drop in BP a line cuz I know some experts are here too. 

thanks all
