What sustains Marbella is scarcity, not season. The Golden Mile and Sierra Blanca are effectively built out, and Andalusia's coastal planning rules make new prime supply almost impossible to add - which is precisely what keeps values resilient through every cycle. Buyers arrive from the Gulf, Scandinavia, the UK, and increasingly the United States, drawn by more than three hundred days of sun, direct access through Malaga airport, and a life that runs year-round rather than for a single summer. Spain closed its property-based Golden Visa in April 2025, yet demand at the top never depended on it; this is a buyer who values privacy, proximity, and a community that moves on relationship. La Zagaleta, Sierra Blanca, and the beachfront of the Golden Mile remain the addresses that hold their value when everything else corrects.
