Best In Luxury Real Estate™

🏆 Ranked #1 in the Nation’s Most Affluent Counties Among Luxury Housing Markets — ALEX Intelligence, 2026. Santa Clara County leads the nation with a median household income of $164,281—surpassing even San Francisco and Marin County—proving that elite real estate is no longer just about price, but about income concentration. This data, drawn from ALEX Intelligence’s proprietary 2026 analysis of U.S. luxury markets, reveals a powerful shift: wealth is not just buying luxury homes—it is creating them. The top 10 counties are not defined by their highest prices, but by their highest median incomes. This means the future of luxury real estate lies not in speculative bubbles, but in sustainable, high-income ecosystems.
