MIAMI—There's plenty of talk about how popular Miami is among foreign buyers. New data backs up that talk.

Attention from foreign consumers searching U.S. properties is increasing, according to the latest figures from the Miami Association of Realtors. South Florida, the top area in the nation for international real estate buyers, remains the focus of consumers from a diverse group of nations.

In March, Miami ranked second only to Los Angeles among the top 10 overall most searched U.S. cities by non-U.S. consumers throughout the month. Miami moved up from fourth place in earlier rankings. Fort Lauderdale ranks eighth. If the Miami-Fort Lauderdale market were combined, the ranking would be even higher.
