Spain is renowned for many things: its culture, its gastronomy, its climate… but there is something else that truly sets it apart — its coastline and exceptional quality of life. With countless sunny days throughout the year, the Mediterranean coast invites you to enjoy golden-sand beaches, whether sunbathing or taking long, leisurely walks. All of this explains why coastal locations remain some of the most sought-after areas for property investment. These are destinations with strong economic activity, consistent tourism demand, employment opportunities and, above all, sustained investment.
Beyond the many benefits of living near the sea, purchasing a property on the coast is a smart decision if you are seeking a fast and solid return on your investment in housing.
Are you looking to invest in a luxury seafront apartment or a second home by the beach? Spain offers a wide range of coastal areas with excellent profitability, outstanding quality of life and strong potential for appreciation. In this guide, we highlight the best places to buy a beach apartment in Spain depending on your goals — whether you prioritise investment, lifestyle or tranquillity.
How can you identify the best area to buy a beachfront apartment? Key factors
If you’re considering where to buy a home by the sea, we recommend assessing these key aspects or consulting a real estate adviser to guide you in these decisions:
- Average profitability and market trends.
- Price per square metre and potential for appreciation.
- Services, infrastructure, and the area’s connectivity.
- Lifestyle (leisure, climate, natural surroundings).
The five best coastal areas to buy a home by the sea
Many people look to invest in seaside property, whether as a second residence or as a way to generate income through holiday rentals or long-term lets.
At Prime Invest, we have compiled the five best areas to buy an apartment on the coast, taking into account the price per square metre, their location, infrastructure, and the quality of life they offer.
The Coast of Valencia
Gandía, in the province of Valencia, is the capital of the La Safor region. Located in the southeast of the Valencian Community, it has long been one of the coastal cities offering the highest returns in residential property.
Its main attraction lies in its beaches and tourism services. In addition, its position on the Mediterranean and proximity to areas such as Jávea or Denia make it an appealing city in which to invest, particularly in properties intended for holiday use.
La Manga del Mar Menor – Costa Cálida
Murcia, the autonomous community known as Spain's vegetable garden, boasts unspoilt coastal areas that attract thousands of visitors each year. La Manga del Mar Menor is one of the parts of Spain with the highest levels of property investment.
The greatest appeal of La Manga del Mar Menor is that it is embraced by two seas: the Mar Menor, the largest saltwater lagoon in Europe, and the Mar Mayor, which forms part of the open Mediterranean.
Roquetas de Mar – Costa de Almería
The coastal area of Roquetas de Mar is situated in southern Spain, in the province of Almería. The district includes several municipalities, such as Roquetas de Mar town, Aguadulce, and El Sabinar.
It is a holiday destination where, for the rest of the year, the atmosphere remains calm and family-oriented. It also benefits from a privileged location close to the Cabo de Gata Natural Park, a protected area known for its golden-sand beaches.
Cádiz – Costa de la Luz
Year after year, Cádiz draws thousands of visitors in search of warm summer days on the Cadiz coastline. Its tourist appeal and privileged position on the Atlantic coast win visitors over. For this reason, many choose to take a step further and purchase a home along its shores, in beach destinations such as Tarifa, Bolonia, Sancti Petri, or Zahara de los Atunes, among others.
Marbella – Costa del Sol
If there is one place in Spain where property value and profitability remain consistently strong, it is Marbella. The exclusivity, natural beauty, and quality of life associated with Marbella make it the most sought-after coastal area in Spain for property.
Known for its Golden Mile, Marbella exudes exclusivity and luxury. The city offers high-quality infrastructure, an endless range of leisure options such as social clubs, internationally acclaimed restaurants, numerous golf courses, and the tranquillity of life by the Mediterranean breeze.
Marbella forms part of the Costa del Sol, one of the European regions with the highest number of sunny days per year—no fewer than 320. This is one of the major reasons it stands out as one of the best coastal areas for property investment.
It is also a unique enclave, with natural spaces of great value such as the Artola Dunes, just 14 kilometres from Marbella, and thanks to its proximity to inland towns in the province of Málaga, such as Ronda or Tolox.
Since the pandemic, it has been one of the cities with the highest demand for property. The main motivations for investing in Marbella revolve around the search for a place that offers not only a wide range of activities but also exclusivity, peace, and closeness to nature.
It is an ideal location in which to invest in a first or second residence, or in a property for rental purposes, whether long-term or holiday, thanks to its secure investment returns.
