Overall, International Interest in U.S. Real Estate Has Waned

Despite plummeting prices, international interest in United States property cooled in the last year, according to an annual survey by the National Association of Realtors, a U.S. organization of property agents.

From May 2008 to May 2009 foreign nationals purchased an estimated 154,000 homes in the United States, down from 170,000 in the previous 12 months, the survey found. Twenty-three percent of the agents questioned reported at least one contact with an international client, down from 26 percent in 2008 and 32 percent in 2007.

And agents in the top four states for international sales — Florida, California, Texas and Arizona — reported their international business actually increased 35 to 45 percent in the period.

In May 2009, with currency exchange ranges fluctuating, the average U.S. home price was $218,300, compared with $278,100 in Canada and $237,900 in Britain, according to the association’s data.

International buyers paid a median price of $247,100 for existing homes, compared with a median sales price of $198,100 in 2008, the new study found. Buyers from India paid the highest median price, $322,200.

Most international buyers came from Canada, Britain, Mexico, India and China, in that order, the survey showed. And while the numbers from Canada, Britain and China declined, those from Mexico and India increased.
