The Costa del Sol has cemented its position as one of Spain’s leading new-build property markets, accounting for one in five newly built homes advertised for sale nationwide.
According to Q3 2026 data from Brains Real Estate, 11,233 new-build properties were listed across 14 municipalities along Málaga’s coastline. The average asking price reached €6,154 per square metre, representing a 3.3% annual increase and standing 27.8% above the national new-build average.
Estepona leads the country in new-build property listings, with 2,279 homes advertised for sale, surpassing Madrid’s 1,959. Mijas follows with 1,878 properties, Marbella with 1,685 and Fuengirola with 1,415, highlighting the concentration of residential development along the Costa del Sol.
Benahavís remains the region’s most expensive municipality for new-build homes, averaging €7,939 per square metre, followed closely by Marbella at €7,656. Meanwhile, Manilva recorded the strongest annual price growth at 15.8%, followed by Vélez-Málaga at 15.4% and Casares at 13.7%.
The figures also reveal significant differences between coastal markets. New-build properties in western Costa del Sol municipalities average €6,266 per square metre, compared with €3,954 in the eastern coastal municipalities.
The region’s combination of international buyers, second-home demand and residential investment continues to attract developers, particularly in Estepona, Marbella, Mijas and Fuengirola.
With new-build supply concentrated along the western coastline and prices continuing to rise, the latest figures reinforce the Costa del Sol’s importance within Spain’s residential property market.
