Is Spain Still a Good Property Investment? Why Sotogrande Stands Out in 2026

Spain is coming off a record year. In 2025, 714,237 homes changed hands, the most since 2007. In 2026, sales are down 3% so far, and in July notaries signed 11.1% fewer home sales than a year earlier.

The main reason is the cost of borrowing. The European Central Bank raised interest rates in June and September, its first increases since 2023. Twelve-month Euribor, the rate most Spanish mortgages follow, averaged 3.247% in September, against around 2.17% a year earlier. New home loans in Andalucía fell 9.3% in July alone.

But this is a market cooling from a record, not collapsing. House prices were still up 12.2% in the second quarter (idealista), Spain is short of around 750,000 homes (Banco de España), and foreign buyers made up a record 15.98% of purchases in the same quarter, led by the British, Dutch and Germans. Household debt is at its lowest share of GDP since 1999, so there are few forced sellers. We set out the full picture in our Sotogrande Property Market Q3 2026 report.

When borrowing gets more expensive, the areas that hold up best are the ones that depend on it least: places where buyers pay cash, come from abroad and buy for lifestyle as much as for return. Along the Costa del Sol and its western edge, prices in the prime areas are still rising.

Sotogrande is the most affordable of these prime locations, about a third below Marbella per square metre, yet among the fastest rising.

Sotogrande is a private residential estate on Spain’s southern coast, in the province of Cádiz in Andalucía. It belongs to the municipality of San Roque, sits at the western end of the Costa del Sol and borders Gibraltar. It is known for golf, including Real Club Valderrama, which hosted the 1997 Ryder Cup, as well as polo, its marina and an international school.

The estate has distinct areas: Sotogrande Costa by the beach, the Marina with its waterfront apartments, Sotogrande Alto on the ridge above, and La Reserva, where much of the new-build and off-plan stock is.

Sotogrande runs on a different clock because its buyers do. Between half and three quarters of the homes we sold in the third quarter were bought without a mortgage, and every buyer who did borrow could have paid cash. This year, 82% of our buyers came from abroad. For them, Euribor is a headline, not a monthly payment.

Currency has helped too. The pound buys about 2.4% more euros than a year ago, so a €3 million villa costs a London cash buyer roughly £62,000 less than it did last year. Compare that with a family in Madrid on a €1 million variable mortgage, now paying around €10,800 more in interest in the first year.

That’s why we describe Sotogrande as insulated, not immune. It isn’t sealed off from the rest of Spain, but the forces cooling the national market reach it far more weakly.

Asking prices in Sotogrande reached a record €4,082/m² in September, up 11.1% in a year, according to idealista. At Open Frontiers, enquiries and offers are both up on 2025, and sellers are giving less room to negotiate, not more. The Marina hit a record €4,375/m² (+21.8%), Sotogrande Costa, where rebuilds are reshaping whole streets, is up 21.4%, and Sotogrande Alto, which idealista groups with La Reserva, rose 9.9% in three months.

It’s rare. Of the 752,661 home sales signed before Spanish notaries in 2025, just 205 were in Sotogrande, roughly one in every 3,700. In a market this small, a handful of sales can swing the official averages, as we showed in our analysis of Sotogrande’s real price growth.

It’s still good value. Even at a record, it sits about a third below Marbella per square metre.

It has a track record. After the last crash, Spanish house prices fell around 37% from peak to bottom. Yet Marina apartments bought new in 2006 have since sold for more than their original price. By contrast, the rest of the San Roque municipality, outside Sotogrande, still sits about 15% below its 2010 peak.

Sotogrande has always been a place people come back to, with Gibraltar’s airport a short drive away. Since 15 July, the EU–UK treaty has also removed physical border controls at Gibraltar.

For owners who want to rent when they’re not using the home, a tourist licence has become an asset in its own right. Since April 2025, a new holiday let in an apartment building needs the approval of three fifths of the owners, but existing licences stay with the property when it’s sold. San Roque is granting new licences again where the building’s community allows it.

Open Frontiers has worked in Sotogrande since 1996. We follow this market sale by sale, from the Marina to La Reserva, and publish regular market reports, such as our Sotogrande Property Market Q2 2026 report, so our clients can decide on evidence rather than headlines. Whether you’re looking at an investment, a second home or both, we’re happy to talk it through.
