End of an era as China's love affair with US real estate fades

For David Wong, the business of selling homes isn't as good this year as it was in 2015, and he's blaming that on a decline in customers from China.

"The residential-property market here, especially for those priced between $2.5 million to $3 million, has been affected by China's measures to control capital flight," said the New York City-based Keller Williams Realty Landmark broker. "You need to cut the price, or it may take a real long time."

Wong is not the only one who has felt the cooling in the US real estate market for foreign buyers. Total sales to Chinese buyers in the 12 months through March fell for the first time since 2011, to $27.3 billion from $28.6 billion a year earlier, according to an annual research report released by the National Association of Realtors. The number of properties purchased by Chinese also declined to 29,195 units from 34,327 units.
