MIAMI—For all the talk of foreign buyers flocking to Miami to snap up condos, there's another demographic that's migrating south: New Yorkers. Indeed, multiple condo developers and sales teams are reporting a marked uptick in New York condo buyers returning to Miami.

At Palau in Sunset Harbour, the latest boutique condo by SMG Management, developers report that nearly 40 percent of buyers are from the United States, and a large number of those are from the Northeast and New York in particular. The majority of the rest accounting for local buyers.

Meanwhile, Edgardo Defortuna, CEO of Fortune International, which is most recently developing Jade Signature in Sunny Isles Beach, reports an approximate 15% increase in New York buyers overall this year. And at The Ritz-Carlton Residences in Singer Island, where the developer recently announced 80% sales, the sales team reports that there have been 12 Northeast buyers in the last six months alone.
