Behind the towering mahogany gates of Miami Beach’s Allison Island, the Wall Street South movement is showing its most permanent face yet. It’s not just about the zero percent state income tax or the deepwater docks; it’s about the ‘Attention: children playing’ signs along the streets.
As old subways struggle with urban decay and rising crime, this private sanctuary is being transformed into a high-security nursery for the next generation of American industry. Here, fresh modern architecture alternates with baby floats and pool safety nets, proving that for the country’s elite, the move to Florida is no longer a seasonal trend — it’s a multi-generational commitment to safety and common sense.
“So for anyone who wants to move here or is thinking about moving here,” he added, “I think if you ultimately weigh the pros and cons, they will quickly realize that South Florida is exactly where everyone seems to want to be.”

Allison Island’s newest neighbor is Google co-founder and billionaire Sergey Brin, who paid $51 million for LVMH CEO Michael Burke and his wife, Brigitte Burke’s modernist, palatial residence in a reported off-market deal. Just a few weeks later, rapper Lil Wayne sold his island mansion for $33 million.

With fewer than fifty single-family homes, the conversation among relocating elites has shifted from, “Can we move?” to, “How fast can we get there?” For the CEOs who come from New York, California and Washington, architecture is the key, but the financial and political environment is all the closer.
“It always starts with the property first, so the client is attracted to the architecture of the property, the style, the location, if it’s on the water,” Kay noted, “but then I think it quickly shifts more to the financial part of the decision. And with the people we’ve dealt with moving here from New York and now California, I think it’s become both an emotional and a strategic decision for them because they ultimately realize that not only can they improve their lifestyle, but they’re also taking a very smart financial decision.”
While the property controlled all the luxurious amenities, the signs of everyday family life felt more impactful. In addition to the flamingo floats and pool safety net, there were baby items on the counter and a high chair ready for use. It was a clear indication that parents and their young children are not just on vacation, but permanently planting their flags in a haven of safety and freedom that they want to call home for decades to come.
“Most of the people we’re dealing with right now are part of this ultra-high-net-worth class. I think the first thing they’re looking for is really safety and security, especially in the current climate,” Kay said. “I don’t think safety and security is really optional anymore, it’s really become a priority for these people.”

“With what’s going on in New York, California, Chicago and other major metro areas, I think the ultra-wealthy class, who are very concerned about privacy and security and ultimately want their families to feel safe, feel like they have the ability to achieve that here in Miami Beach,” he continued. “We’ve really had an inventory problem here in South Florida since the days of COVID. So when buyers see the opportunity to buy something like this, they don’t even hesitate. They’re not thinking in terms of months or even years, they’re thinking in terms of decades right now.”
“The number of people moving and settling here on a more full-time basis far exceeds the number of properties that we actually have to sell to these people. The transaction level and the volume and price growth that we’ve seen over the last few years is something that I don’t think any of us could have predicted.”
While Indian Creek offers isolation, Allison Island offers something rarer in the ultra-luxury world: a neighborhood. Kay notes that the influx of names like Brin is not just a real estate play, but also a cultural play.
“It’s become more of a full-time service, so the families that have moved here now… the reason they’re doing this again is because of the location, the privacy aspect, the security of being behind a guard gate, the scarcity of waterfront land here in Miami Beach, which they no longer benefit from,” Kay explained. “But I think what really makes Allison Island unique is the fact that it has a real sense of community.”
That community offers a level of freedom that has disappeared in other major American cities.

“They don’t have to worry about the unknown or the unexpected. Their kids can go for a walk or ride a bike or do things, and they don’t have to sit there and worry about that,” Kay said. “But at the same time, they know they are upgrading their lifestyle while still ultimately making a very smart financial decision.”
