Spain’s coastal property market is entering one of its most dynamic phases in recent years. Increased international demand, continued infrastructure investment and a strong pipeline of high-quality developments are positioning several towns as standout locations for 2026. While some destinations are already well known, they are undergoing significant changes that are set to reshape local markets and elevate long-term value.

Below is a detailed overview of the areas expected to attract increased attention from buyers and investors throughout 2026.

1. Torrevieja: A Familiar Name Entering a New Phase of Growth

Torrevieja may already be a recognised location on the Costa Blanca, but it now finds itself at the beginning of a major transformation. For many buyers, it will be surprising to see Torrevieja on a list of emerging hotspots, yet the scale of recent investment firmly supports its inclusion.

Several key developments are set to influence the market:

• The opening of the new marina at Easter, which will uplift the waterfront and attract higher-end tourism and commercial activity
• The significant new project in La Hoya, bringing improved infrastructure, green spaces and residential growth
• Continued public improvement works throughout the promenade and central areas

These changes are strengthening Torrevieja’s position as a modern, appealing coastal city. Prices remain competitive relative to other Mediterranean locations, creating strong potential for medium-term appreciation.

2. San Miguel de Salinas: A Market With Room to Expand

San Miguel de Salinas has steadily grown in popularity, particularly among international buyers seeking a balance between coastal access and a quieter residential environment. The town benefits from ample surrounding land, which has allowed new developments to flourish, something that is increasingly rare in coastal municipalities.

Market drivers include:

• Extensive availability of new-build plots, supporting modern residential communities
• High demand for properties in the district on the edge of town, which has become a preferred choice for overseas buyers
• Proximity to Orihuela Costa, beaches and golf facilities, while maintaining lower price points

San Miguel is well positioned for further growth throughout 2026 as new developments reach completion and wider buyer awareness increases.

3. Finestrat: The Costa Blanca’s New Luxury Hub

Finestrat, particularly the hillside areas overlooking Benidorm, has become one of the strongest performers on the Costa Blanca. The zone has emerged as a focal point for high-quality new-build projects and continues to attract a global audience.

Key strengths include:

• Panoramic sea and skyline views
• Contemporary architectural styles across villas, apartments and townhouses
• Strong holiday rental demand due to proximity to beaches, leisure attractions and amenities
• Excellent access to schools, shopping facilities and major transport routes

Finestrat represents one of the most compelling luxury markets in the region, with continued upward movement expected in 2026.

Costa del Sol Markets to Watch in 2026

The Costa del Sol has long been a magnet for international property buyers, yet several towns are experiencing a renewed surge of interest driven by upgraded infrastructure, residential investment and evolving buyer preferences.

4. Estepona: A Leading Coastal Market

Estepona has undergone a complete transformation in recent years and is now regarded as one of the strongest property markets in southern Spain. Continued investment from both the public and private sectors has positioned the town as a modern, attractive and highly liveable destination.

2026 growth factors include:

• Ongoing enhancements to the beachfront, promenade and Old Town
• A robust pipeline of new developments with contemporary designs
• Consistent demand from Northern European markets
• A reputation as a calmer alternative to Marbella without sacrificing premium quality

Estepona is expected to maintain its trajectory as one of the Costa del Sol’s most desirable locations.

5. San Pedro de Alcántara: High Demand Adjacent to Marbella

Located between Puerto Banús and Estepona, San Pedro de Alcántara has seen a marked rise in popularity. Its family-friendly environment, walkable beachfront and recent development activity have placed it firmly on the radar of both lifestyle buyers and investors.

Market strengths include:

• Growing demand from buyers seeking Marbella proximity at more accessible prices
• Attractive new residential projects
• A wide, well-maintained promenade that appeals to long-term residents and holidaymakers alike
• Strong year-round rental potential

San Pedro is increasingly seen as an extension of Marbella’s premium zone, but with its own distinctive character and value proposition.

6. Casares Costa: A Quiet but Significant Emerging Market

Casares Costa remains one of the lesser-known markets on the Costa del Sol, yet its combination of natural scenery, high-quality developments and resort-style communities has made it a rising favourite among informed buyers.

Key advantages include:

• Attractive gated communities with strong amenities
• A peaceful setting close to Estepona but without the associated price levels
• Increasing interest from remote workers and semi-retirees
• Solid long-term potential supported by ongoing regional development

Casares offers a refined coastal lifestyle and is expected to gain further visibility throughout 2026.

Conclusion

The year ahead is shaping up to be pivotal for many Spanish coastal markets. Torrevieja, San Miguel de Salinas and Finestrat provide strong opportunities on the Costa Blanca, each driven by distinct development trends and buyer profiles. Meanwhile, on the Costa del Sol, Estepona, San Pedro de Alcántara and Casares Costa continue to strengthen their positions as some of southern Spain’s most promising destinations for both residential and investment purposes.
