Caution advocated on real estate purchases in Portugal as Chinese buyers burn their fingers, reports Bloomberg.

Billboards in Chinese at Lisbon's international airport peddling luxury properties leave little doubt about who is buying real estate in Portugal.

While the ads offer a chance at securing a so-called golden visa to live in Portugal in exchange for property investments of at least 500,000 euros ($559,000), they leave out the golden rule of such purchases: never rush into a deal.
