hi jim
justa a thought on your 1st post.
i wouldn't advise having it that way, that is if you're investing on a property here (not necessarily a house and lot / tract of land). instead foreigners can own a condo unit, and lease it (your GF can help while you're away) atleast you get to own the property.
It is BETTER buy something for a wife (not a GF) but its BEST if you own it
