New developments in Spanish property for 2026: opportunities and trends for British investors

Moving to or investing in Spain, particularly on the Costa Brava, has never been more attractive than in 2026. For IMMO 365 Costa Brava, an agency specialising in sales to the British market (in the areas of Roses, Empuriabrava, Platja d'Aro and Cadaqués), several favourable factors are coming together: climate, quality of life, strong demand and good prospects for appreciation.

We will first look at the major market trends, then focus on what makes the Costa Brava so attractive, before giving you the keys to making your project a success.

Spanish property market trends in 2026

Supply under pressure, prices rising moderately

The shortage of new or renovated housing in Spain is a key factor supporting prices: according to a study by Singular Bank, prices could rise by around 9% between 2025 and 2026.

Another figure: an increase of around +4% to +5% in 2025 in certain areas, indicating an active market, but without a speculative bubble.

This is therefore an interesting period for French buyers: prices remain reasonable compared to other Mediterranean countries and the trend is upwards, encouraging quick decision-making.

The drivers of property growth

Among the drivers are:

• Significant foreign and secondary demand on the coast: holidays & second homes.
• Supply constraints (land, regulations, energy expenditure, standards).
• Environmental awareness and energy efficiency in the property sector: insulation, solar panels, eco-friendly construction.
• Attractive potential returns on rental investments (seasonal or annual) in tourist or coastal areas.

What are the concrete prospects for 2026?

For a British investor or buyer targeting the Costa Brava:

• Given the moderate rise in prices, it seems wise to buy before a stronger ‘rise’.
• Prioritise well-located properties (sea view, proximity to amenities, nature) to maximise value.
• Find out about new regulations (tourist rentals, energy standards) to avoid unpleasant surprises.

Focus on the Costa Brava: advantages & location

Why is the Costa Brava a remarkable investment opportunity?

The Costa Brava, in the province of Girona in Catalonia, combines Mediterranean coastline, typical villages, unspoilt nature and relatively easy access from France. The IMMO 365 Costa Brava agency operates in key areas: Roses, Empuriabrava, Platja d'Aro and Cadaqués.

These places appeal for their quality of life, charm and the combination of sea and nature.

Nature as a factor in value appreciation

One of the major advantages for French buyers is the proximity of large protected natural areas. Natural parks add value to properties because they provide a sustainable, protected environment that is not subject to massive urbanisation.

Among the major parks are:

• Cap de Creus Natural Park: located in the north of the Costa Brava, a spectacular coastline between land and sea.
• Aiguamolls de l'Empordà Natural Park: a wetland between Roses and Empuriabrava with remarkable biodiversity.
• Montgrí, Illes Medes and Baix Ter Natural Park: between land and sea, an underwater reserve and a magnet for nature lovers.

This ‘nature’ dimension is a strong marketing argument for French investors, who are often sensitive to preservation and quality of life.

Key areas & property types

• Roses / Empuriabrava: ideal for second homes, seasonal rentals, quiet and natural, yet well connected.
• Platja d'Aro: a little more of a ‘seaside resort’ and lively, a good compromise between tourism and stable residential living.
• Cadaqués: high-end, unique charm, more exclusive, therefore more expensive, but with strong potential for appreciation.
• Tip: favour properties with sea views, close to amenities, and check the condition (renovation, insulation) as costs can rise on this coastline.

New developments and 2026: what to watch out for

Standards & sustainability

Spain, like the rest of Europe, is seeing its energy and environmental standards tighten. New and renovated buildings must be efficient in terms of insulation and consumption and, if possible, integrated into a sustainable framework. This point is increasingly being taken into account by French buyers.

For IMMO 365 Costa Brava, this is an argument to be emphasised: ‘investing in a sustainable property = lower running costs + better resale value’.

Seasonal rental investment: new rules

The Spanish coast is in high demand for tourist rentals. However, some municipalities are tightening controls (rental registration, tax, safety standards).

In 2026, it will therefore be necessary to:

• Check that the property complies with tourist rental regulations
• Also consider long-term rentals, which are less ‘flexible’ but more stable
• Anticipate maintenance costs and late payments (management from abroad)

Timing and use of the investment

For a British buyer, there are two overlapping uses: second home + investment. The 2026 market suggests:

• Buy now to take advantage of prices that are still affordable and anticipate the increase.
• Choose the location carefully to recoup the amount invested and obtain a return on your investment.
• Don't just focus on the price per square metre, but also on the ‘perceived value’: accessibility, views, proximity to nature, quality of construction.

Checklist for a successful project with IMMO 365 Costa Brava

Before purchasing

• Define your budget and use (residence vs. rental).
• Visit several properties in the targeted areas (Roses, Empuriabrava, Platja d'Aro, Cadaqués).
• Check the condition of the property: renovation work, insulation, facilities, sea view.
• Find out about taxes, purchase costs and taxation as a foreigner.
• Check whether the property is suitable for tourist rental or as a second home.

At the time of purchase

• Negotiate based on the condition and location.
• Ensure that the technical and energy diagnostics are up to date.
• Plan for management, maintenance and possible renovation costs.
• Ensure that the local agency (such as IMMO 365 Costa Brava) has a good understanding of the French-Spanish market (language, taxation, follow-up).

After purchase

• If renting: choose between seasonal or long-term depending on return and time available.
• Property maintenance, enhancement (e.g. proximity to natural park, sea view).
• Monitor market developments: prices, demand, regulations.
• Consider resale or inheritance: properties in good locations on the Costa Brava have strong potential for appreciation.

Frequently Asked Questions (FAQ)

Should you buy now or wait?

It seems sensible to buy now in 2026: supply is under pressure, price increases are moderate but confirmed, and the coastal area is well positioned. Waiting could lead to paying more while having less choice.

What are the additional costs of buying in Spain?

In addition to the purchase price, you should expect to pay: solicitor's fees, purchase taxes, property tax, possibly management/rental fees if you rent out the property, renovation or energy efficiency upgrades.

Is a property in a natural park a good investment?

Yes: properties near or within protected areas such as the Costa Brava's natural parks benefit from more stable values, a preserved environment and attractive rental potential (quality of life, nature). For example, the Costa Brava's natural parks are among the most beautiful in the region.

However, it is important to check the constraints (local regulations, access) and choose a property in the right location.

Is this a risky market for a British investor?

All investments involve risk: regulation, interest rate fluctuations, seasonality. But the Spanish coastal market, and the Costa Brava in particular, has solid fundamentals (foreign demand, nature, quality of life) that reduce the risk. With the right support (such as IMMO 365 Costa Brava), French investors can secure their project.

What kind of return can be expected from seasonal rentals?

The return depends greatly on the location, the condition of the property and how it is managed. The highly touristic areas of the Costa Brava can generate attractive income, but maintenance costs, low seasons and remote management must also be taken into account. It is advisable to make a personalised estimate before committing.

Conclusion

The year 2026 looks set to be a strategic moment to invest in Spain, and even more so on the Costa Brava. Thanks to solid demand, limited supply and the strong appeal of the coastline, the conditions are right for British buyers looking for a quality property close to nature in a tourist or residential area.

With the expertise of a local agency such as IMMO 365 Costa Brava, you can not only choose the best location (Roses, Empuriabrava, Platja d'Aro, Cadaqués) but also access multilingual support tailored to your needs.
