Spain’s‑prime mansion market is riding a wave of record foreign demand, with nearly 100,000 properties acquired by international buyers last year. From Marbella to Madrid, global wealth is competing for expansive estates in tightly held enclaves — but which locations are truly leading the market?

Spain’s prime property market is forecast to rise by up to 10% in 2026, fuelled by sustained international demand across southern and eastern hotspots. With branded residences and lifestyle-driven investment surging, certain markets are emerging as clear frontrunners for the year ahead.

Suspended above the Atlantic in Los Gigantes, this 370 m² cliff-top penthouse pairs panoramic ocean views with rare privacy and a private infinity pool. Offered at €2,090,000, it represents one of Tenerife’s most dramatic residential opportunities — and a setting few properties can rival.

Estepona has quietly become the Costa del Sol’s fastest-rising luxury powerhouse, with new-build prices reaching €7,000 per square metre. Backed by major public investment and international demand, three key enclaves are redefining its status within the Golden Triangle.
