Why it matters

Money Landscape
California's current 57% share of the country's most expensive ZIP codes represents a notable shift from the 73% share held in 2019. While the state remains a national leader in high-cost housing, these figures illustrate how price concentrations have fluctuated over the last seven years.
Prospective buyers in high-cost California markets should review how these local median prices compare to their own borrowing capacity and long-term budget goals. Consult with a qualified financial professional to assess how regional housing trends impact your personal real estate strategy.
The takeaway
While California ZIP codes still make up the majority of the nation's most expensive markets, their total share of the list has decreased since 2019. Homeowners should track their local ZIP code's median pricing against these annual benchmarks to understand their home's relative market position.
