Well, Canadians like warm weather and florida has cheapened. Other than that, we are the real estate version of safe money market account. Chinese and russians will always want the safe ny condo even if it means giving up 20% in their home market. It's about what could go wrong over there(10% down in ny means nothing)

Wouldn't the percentage be up just because Americans are buying fewer?

Same in Canadia: http://www.theglobeandmail.com/news/national/foreign-investment-cuts-both-ways-in-toronto-condo-market/article4246468/

Think it is just that people no longer trust putting their money in the markets (and useful to launder).

Or just that Americans are buying even less.
