The Marbella arc: most of the Costa del Sol luxury market
The overwhelming majority of the Costa del Sol register above €1.5M sits inside the Marbella–Benahavís–Estepona corridor. This 35-kilometre stretch contains La Zagaleta, the Golden Mile, Sierra Blanca, Nueva Andalucía, Puerto Banús, and the New Golden Mile — collectively over 90% of the residences we track. That is a statement about listed supply, which we can count, and not about closings, which nobody can: Spain publishes no per-property transaction data.
Within the Marbella arc, prices range from €9.4M median in La Zagaleta to €2.4M median in Estepona's New Golden Mile. The common thread: golf, sea proximity, international airport (Málaga AGP, 25–60 minutes), and a critical mass of luxury hospitality that generates the social infrastructure buyers expect.
Sotogrande: the polo alternative
Sotogrande offers a materially different residential character from Marbella: 2,000 hectares of private estate in Cádiz province, 90 km west of Marbella and 30 km north of Gibraltar. The anchors are polo (three international grounds, including the Santa María Polo Club), Valderrama Golf, and one of Spain's highest-regarded international schools (ISS Sotogrande).
The Sotogrande register above €1.5M holds approximately 39 villas (June 2026), with a median of €3.5M and an average of €5,378/m² — a discount to Marbella prime that reflects the greater geographic remoteness from Málaga airport.
Estepona: the emerging sector
Estepona's New Golden Mile is where new-build supply on the Costa del Sol luxury axis has concentrated, at prices below the Marbella comparable. The active register above €1.5M holds 119 properties with a median of €2.4M and €5,928/m² — roughly 35% below the €9,276/m² we record on the Marbella Golden Mile, asking against asking.
The tradeoff is location: Estepona is 30 minutes from Puerto Banús and 55 minutes from Málaga airport. The luxury hospitality infrastructure — five-star hotels, private beach clubs — is thinner than the Marbella core. For new-build buyers who value larger indoor-outdoor space at a lower entry point, Estepona is the principal opportunity.
