Miami-Dade on pace to break $10M+ sales record
Miami-Dade County is projected to break its annual record for residential transactions exceeding $10 million by year-end, driven by a sustained influx of cash-rich buyers relocating from high-tax jurisdictions. This trend underscores the region's status as a primary destination for UHNW individuals seeking privacy and favorable tax structures, with inventory tightening in prime coastal enclaves like Star Island and Palm Beach.
$28M Chelsea penthouse tops NYC weekly deals
Related Companies closed the sale of a full-floor, 6,300-square-foot penthouse at The Cortland in Chelsea for $28 million, marking the most expensive residential transaction recorded in New York City for the week ending September 18, 2026. The deal highlights continued demand for large-format luxury units in Manhattan’s emerging premium neighborhoods, even as broader market sentiment remains cautious.
Moroccan royal family’s Neuilly mansion sold
A confidential 1,325-square-meter hotel particulier in Neuilly-sur-Seine, previously owned by the Moroccan royal family, was sold to a private French buyer. The property, featuring eight suites, a pool, and a 105-square-meter rooftop with views of the Bois de Boulogne, represents one of the notable trophy asset transfers in the Parisian periphery this month.
"Stealth wealth" drives off-market trophy purchases
Fortune reports that ultra-high-net-worth individuals are increasingly utilizing "stealth wealth" strategies to purchase multimillion-dollar mansions without leaving a public paper trail. By leveraging LLCs, trusts, and private brokerage channels, buyers aim to minimize visibility in luxury real estate records, a trend that complicates traditional data tracking for market indices like those from Knight Frank and Savills.
Local view
Fox Business highlights that Mayor Zohran Mamdani’s proposed pied-à-terre tax in New York has created "confusion" rather than immediate capital flight among wealthy buyers. Brokers report that while high-net-worth clients are scrutinizing tax implications, many are adapting their purchase structures rather than abandoning the Manhattan market entirely.
In Greece, New Greek TV reports that British millionaires are flocking to the Athenian Riviera, motivated by specific tax regimes that differ from the earlier Golden Visa incentives. This shift is fueling a luxury property boom in coastal Athens, as buyers seek residency options paired with lifestyle amenities.
Context & numbers
- Prime Market Growth: Knight Frank’s latest Wealth Report indicates global prime residential prices rose by 3.2% in 2025, with the Middle East leading regional growth at +9.4%. The UHNW population is expected to grow by 28% over the next five years, sustaining demand for trophy assets.
- Tax Policy Shifts: Greece plans to increase the property transfer tax for non-EU buyers from 3% to 15% starting July 2027, potentially accelerating demand before the implementation date. Meanwhile, UK "mansion tax" discussions continue to influence buyer behavior in London’s prime central districts.
- Dubai Momentum: Sotheby’s International Realty notes that Dubai’s luxury sector continues its upward trajectory, driven by record-breaking villa and branded residence sales. Inventory is tightening as new launches become more curated, supporting price growth.
On the radar
- Mamdani Tax Implementation: Watch for further clarity on the NYC pied-à-terre tax details, which could impact Q4 transaction volumes in Manhattan’s top tier.
- Greek Tax Deadline: Investors may rush to close deals in Greece before the 2027 tax hike, creating a short-term surge in non-EU buyer activity.
- Monaco Supply: Limited inventory in Monaco’s Mareterra development continues to drive record prices, with few new listings expected in the near term.
