Global luxury residential prices rose 3.6 percent in 2024, according to Knight Frank's Prime International Residential Index (PIRI 100), which tracks prime property across 100 markets. Of those 100 markets, 77 recorded positive annual price growth. The top performers were concentrated almost entirely outside the traditional luxury heartlands of New York and London — both of which recorded declines in 2024 (−0.3 percent and −1.0 percent respectively, per the same index) and remain below their most recent peaks. The implication for buyers is not that New York and London are finished. It is that the geography of where serious money is flowing has shifted decisively, and that the buyers who identified Miami, Dubai, and select Mediterranean markets a decade ago were following structural signals — tax environment, infrastructure investment, supply constraints, and institutional capital arrival — that were visible to anyone prepared to look for them.

Miami: America's New Financial Capital

Miami's prime residential market appreciated 84 percent from the start of the pandemic through 2024, according to Knight Frank's 2025 Wealth Report — the fourth-highest appreciation of any market tracked globally over the same period. In the 12 months to September 2024, Miami recorded 230 super-prime transactions (properties above $10 million USD), second globally only to Dubai's 388. The driver is not simply transplanted New Yorkers, though that cohort is real and well-documented. It is the structural relocation of financial services: hedge funds, family offices, and private equity firms that moved their headquarters — not satellite offices — to Miami and South Florida. Citadel's 2022 relocation from Chicago is the most cited data point; it is not the only one.

Knight Frank data shows that $1 million buys approximately 60 square metres in Miami today — four times more than Hong Kong (22 sq m) and nearly twice New York (34 sq m). The window of relative value is closing: the gap between Miami's price-per-square-metre and equivalent gateway cities has narrowed materially since 2019, and supply in the premium waterfront segments that function as the long-term store of value remains genuinely constrained.

Dubai: The Genuinely Global City

Dubai led the Knight Frank PIRI 100 in both 2023 (15.9 percent annual price growth) and 2024 (16.9 percent). Prime residential prices in the emirate have risen 147 percent since the start of the pandemic, according to Knight Frank's 2025 Wealth Report — the highest appreciation of any market tracked globally. Yet Dubai remains notably cheaper per square metre than comparable global cities: $1 million buys 91 square metres in Dubai versus 22 in Hong Kong and 33 in London, per Knight Frank's 2024 buying power analysis.

The structural driver is tax. The UAE imposes no personal income tax, no capital gains tax, and no inheritance tax. The government's introduction of long-term residency visas — 5-year and 10-year Golden Visas — for property investors and qualifying professionals formalised what was previously an informal relationship between Dubai and its transient wealthy population. In 2024, super-prime transactions (above $10 million) numbered 388 — exceeding New York's 230 by a significant margin. Dubai is no longer a market driven by speculation. It is a market driven by permanent relocation of wealth.

The Italian Riviera: The Last Great Value in European Luxury Property

Among European markets, Iberia has consistently outperformed the broader region. The Algarve and Ibiza both recorded 12.3 percent and 12.0 percent annual price growth respectively in 2023 (Knight Frank PIRI 100), and Iberia occupied five of the top 20 global rankings that year. The underlying driver parallels Dubai's in one respect: tax policy. Portugal's Non-Habitual Resident (NHR) regime offered flat 20 percent rates on Portuguese-source income and full exemptions on most foreign income — significantly modified at end-2023 for new applicants, but its decade of operation reshaped buyer demographics in Lisbon, Porto, and the Algarve irrevocably. Spain's Beckham Law continues to provide favorable rates for qualifying new residents.

The Ligurian coast of Italy — the stretch between Portofino and Alassio — remains structurally undervalued relative to the French Côte d'Azur. Supply is genuinely limited by geography and Italian planning law: the coastal zone is protected, and most inventory is heritage property that cannot be replicated at scale. Unlike the Côte d'Azur, which has absorbed institutional capital and now trades at institutional prices, the Italian Riviera still reflects local market dynamics — offering villas at significant discounts to equivalent properties in Cap Ferrat or Antibes. This gap is closing as the same buyer cohort that discovered Lisbon discovers Portofino.

Where Is the Next Miami?

Knight Frank's 2025 Wealth Report identified Seoul as the top-performing prime market globally in 2024, with 18.4 percent annual price growth driven by local wealth creation and the expansion of investable luxury residential developments — a different dynamic from Miami or Dubai, where international capital was the primary driver. The structural conditions that preceded Miami's decade of appreciation — favorable tax treatment, improving infrastructure, growing professional class, significant supply constraints, and the initial arrival of institutional capital — are the signals worth monitoring. Markets currently exhibiting some combination of these characteristics include Abu Dhabi, select Southeast Asian cities, and secondary European markets where lifestyle factors are attracting high-earning relocators.

The pattern is consistent. The next market will announce itself through the same signals that Miami and Dubai announced themselves a decade ago. Most buyers will notice when the appreciation is already mature.
