Hello, I have a number of Chinese nationals looking to buy & invest in the booming Collin County, Texas area.

This isn't a Chinese puzzle. 

Many times when I am in the proximity of Chinese tourists (infrequent I have to say) I have noticed that their social space boundaries are different and they are a bit pushier than what I am used to experiencing with Americans.

True there is no market without cycles. however the australian market is the best performing one in the developed economies. though it is dependent on Chinese , the market might have a correction or soft landing but will never crash. there is  acute shortage of houses sort of controlled release of land.

Go to a stone place, usually named like chinese + "cabinets and stones".

Lots of overseas cash in NY and probably elsewhere in the US as well.http://therealdeal.com/issues_articles/the-year-of...This quote is crazy "Chinese buyers have accounted for roughly 25 percent of all buyers for homes $3 million and up in Nassau County between January 2013 and mid-February, she said."

Their answer was that Chinese PM companies are not like US ones and the owners have to be pretty hands on.

If you had a property you were selling in Chinatown or Little Italy in NYC, would you drop flyers at Chinese restaurants and pizza places?

Chinese investment in the Bay Area is decreasing due to increased restrictions by the chinese government (source).
