Spain

Spain's residential market entered 2025-26 in an expansionary phase, supported by resilient demand (job growth and improved mortgage affordability as financing costs ease) and a persistent supply gap. Transaction activity remains high: in November 2025, 58,546 home sales were registered (+7.8% YoY), with 78.2% second-hand and 21.8% new homes. Foreign demand remains structural: overseas buyers were 14.1% of purchases in Q1 2025 and ~14.4% (≈100,000 sales) in the four quarters to Q2 2025. Prices have accelerated as supply lags: INE's House Price Index rose 12.7% YoY in Q2 2025 (12.8% for second-hand). The Registrars' 2024 annual report shows an average price of \'802,086/m\'b2 (+6.3% YoY). On the supply side, starts and completions improved in 2024 (136,187 homes started; 100,980 completed), yet permit volumes and delivery capacity still trail household formation (e.g., 59,341 new-home permits in H1 2025). CaixaBank Research estimates a cumulative deficit of 515k-765k homes over 2021-2024, reinforcing a scarcity premium in prime urban and coastal markets. Consumers are more price-sensitive (Fotocasa reports 90% of buyers prioritise price), and rental regulation creates divergence between asking rents (portals) and signed contracts, complicating underwriting. Digitally, Spain is a mature portal market: Similarweb ranks idealista #1 and fotocasa #2 (Dec 2025), and leading platforms are embedding AI (idealista "smart text", Fotocasa Brain). Investment sentiment improved: CBRE estimates Spain's real estate investment at ~\'8014bn in 2024 (+20% YoY) and expects 10-15% growth in 2025, with Living a preferred sector amid supply constraints. Key 2025 risks include tighter rental/STR compliance (national registry), shifting foreign-buyer policy, and the end of residence-by-investment via real estate ("Golden Visa"). Opportunities cluster in build-to-rent, flex living, and energy-efficiency retrofit pipelines.

Spain's portal market is entering a period of structural transformation driven by Scout24's acquisition of Fotocasa and Habitaclia (announced 2025), which would — if completed without significant regulatory intervention — create a de facto duopoly between idealista and a Scout24-backed second player. This is a significant structural change for the Spanish market, which has historically operated with a dominant leader (idealista), a strong challenger (Fotocasa), and a cluster of secondary portals (yaencontre, pisos.com, Kyero for international buyers).

For idealista, the competitive environment in 2026 is the strongest test of its market position in its history. Scout24 brings deep product expertise (ImmoScout24 in Germany is one of Europe's most advanced portal platforms), international comparative intelligence, and significant financial capacity. idealista's response is to deepen its AI and data moat: the 'smart text' natural-language search filter launched in Spain in 2025 is the most significant portal feature innovation in the Spanish market in several years, enabling buyers to describe property requirements in natural language rather than selecting filter checkboxes. This reflects a broader strategic bet that AI-native search will become the primary discovery interface for the next generation of property buyers.

The foreign buyer segment adds a distinctive layer to Spain's portal dynamics. Spain abolished its 'Golden Visa' for real estate investment in 2025, which removed one pathway for non-EU foreign nationals to acquire residency through property purchase. However, demand from EU citizens (particularly Germans, French, British, and Scandinavians) for Spanish vacation and lifestyle property remains strong and does not depend on Golden Visa availability. Portals like Kyero that specifically serve the international buyer segment, alongside idealista's English-language interface, continue to benefit from this structural demand.

The short-term rental market in Spain is the most heavily regulated topic in the portal industry. Royal Decree 1312/2024 establishing the Registro Único de Arrendamientos created a national registration requirement for tourist rentals with a display and verification obligation effective from 1 July 2025. Spain's reported €64 million fine of Airbnb for unlicensed tourist rental listings signals that enforcement will be meaningful. For traditional residential portals, this regulatory pressure creates an opportunity: landlords exiting the short-term rental market due to compliance cost and uncertainty will return to the long-term rental market, increasing rental inventory on platforms like idealista and Fotocasa.

For operators in the Spanish market in 2026: idealista is the non-negotiable first portal for residential reach across Spain's major markets. The Scout24/Fotocasa combination warrants close monitoring as it develops, as Scout24's product investment could materially improve Fotocasa's listing quality tools and analytics capability. Smart text search on idealista rewards listings with detailed, narrative-style descriptions that mention lifestyle attributes, proximity features, and neighbourhood context — agents who adapt their listing copy for AI-parsed natural language will see better discoverability. The rental regulatory environment requires active attention to registration number compliance from 1 July 2025.

Spain's new homes market is experiencing developer confidence recovery after the 2022-2024 construction slowdown, with coastal and sunbelt development — Alicante, Malaga, Valencia, and Mallorca — showing renewed developer activity driven by sustained international lifestyle demand. Portals like idealista and Fotocasa are investing in new homes product features: developer project pages, off-plan search filters, and VPOAM (protected housing) filters for first-time buyer segments. For agents with developer relationships, the portal-level new homes tools are increasingly important for early pre-launch buyer registration and digital marketing — particularly for international buyer audiences who are the primary demand driver for new coastal and urban investment developments. Agencies active in coastal and island markets (Costa del Sol, Mallorca, Valencia, Alicante) should ensure their idealista and Fotocasa listings are optimised for English, German, and French-language search terms, as the lifestyle migration buyer segment is the most active demand driver in these submarkets for 2026.
