Mortgages for Non-USA based investors

[Jeffrey Asselstine]

I am a Canadian national living in the Middle East, and am looking to invest in the USA. However, I am very unsure as to what options are open to me for mortgage finance.  30 year rates look exceptional, but am not aware if I can avail of these facilities.  Any suggestions would be greatly appreciated.

I have set a Florida Post Code as this is where my brother lives, otherwise, I am not able to post.
