If your intention is to search in the southern mainland, the ideal choice is to look at the Andalusian coast, focusing on the province of Huelva with towns like Cartaya, or in Almería with traditional hubs such as Adra. For those who prefer the Levante coast, the province of Castellón offers the most competitive prices in areas like Burriana, while if we look towards Catalonia, the province of Tarragona is the best alternative to cut purchasing costs, especially around Alcanar.
On the other hand, if you are more drawn to the north of Spain, the coasts of Galicia and Cantabria hide magnificent opportunities if you focus on coastal fishing towns like Cedeira or Bárcena de Cicero. Finally, if your dream is to live on the islands, it is also feasible to find balanced options if you step away from the most crowded spots and look into locations such as Ingenio in the Canary Islands or more moderate areas of the Balearics like Manacor.
