According to a new UBS Global Real Estate Bubble Index report, Miami has surpassed Los Angeles and New York City as the global housing market with the highest bubble risk, with a score of 1.73 that exceeds the 2006 pre-crisis peak. The report cites Miami's rapid home price appreciation, worsening affordability, and rising maintenance costs for older condos as factors driving the bubble risk.

Why it matters

Miami's designation as the world's riskiest housing market raises concerns about the sustainability of the city's real estate boom, which has attracted an influx of wealthy residents fleeing high-tax states. A potential housing downturn could impact the broader economy and disrupt the lives of middle-class residents struggling with rising costs.

The details

Over the past 15 years, Miami has posted the strongest inflation-adjusted housing appreciation among all cities studied by UBS. While Florida's tax-friendly climate continues to lure billionaires, local homeowners are facing a perfect storm of record-low affordability, massive condo repair bills, and surging insurance premiums. The report notes that worsening affordability and widening gaps between prices and rents have historically served as precursors to housing crises.

  • The UBS Global Real Estate Bubble Index for 2025 placed Miami in the top spot for highest bubble risk.
  • Over the last 5 years, inflation-adjusted home prices in cities with elevated or high bubble risk increased nearly 25%, while rents rose about 10% and incomes about 5%.

What’s next

The report suggests that while a sharp housing correction in Miami is unlikely in the near term, the city's real estate market remains highly vulnerable to a potential downturn.

The takeaway

Miami's designation as the world's riskiest housing market underscores the fragility of its real estate boom, which has been fueled by an influx of wealthy residents seeking tax havens. This raises concerns about the long-term sustainability of the city's housing market and the potential impact on middle-class residents struggling with rising costs.
