Idealista's May 2026 Asking-Price Tape Marks €3,142/m² Across Portugal — Seventh Straight Monthly High as Lisboa Crosses €6,124, Santarém Climbs +30.9% YoY and the National Index Notches +10.2%
idealista's May 2026 index puts the national median asking price at €3,142/m², a seventh straight historic peak, with Lisboa at €6,124, the Algarve at +10.7% YoY and Santarém leading district capitals at +30.9%.
The idealista price index for May 2026 puts the national median asking price at €3,142 per square metre, a fresh historic peak and the seventh consecutive monthly high in a series that has not produced a backward step since November 2025. The tape, released at the start of June, brackets the residential market in a continued upcycle even as transaction volumes show the first signs of buyer caution flagged in early-May data.
The year-on-year change holds at +10.2% with the quarter-on-quarter print at +2.4%, keeping Portugal inside the top three OECD jurisdictions for annual residential price growth this cycle.
Regional Spread Widens
The regional cuts reinforce how thinly the national headline summarises a market split into separate price worlds. The Área Metropolitana de Lisboa leads at €4,391 per m², up 9.2% on May 2025, with the Algarve a close second at €4,057 (+10.7%) and the Região Autónoma da Madeira third at €3,647 (+9.1%). The Norte prints €2,555 (+8.2%), the Alentejo €2,049 (+19.9%) and the Centro €1,794 (+15.4%) — the cheapest region on absolute price but the third-fastest mover on annual change.
At district-capital level the dispersion is sharper. Lisboa city sits at €6,124 per m², roughly double the Setúbal figure of €3,108 and almost six times Castelo Branco's €1,050. Porto holds second city at €4,064, Funchal third at €3,863, Faro fourth at €3,792 and Setúbal fifth, completing a top tier where every entry now sits above the €3,000/m² mark for the first time on the idealista series.
Interior Districts Carry the Annual Move
The fastest year-on-year movers among district capitals are no longer the headline metros. Santarém clears +30.9% on the year, Portalegre +28.2% and Beja +23.6%, the three pulling the Alentejo and Centro regional aggregates higher. The signal is consistent with the idealista narrative through the first half of 2026: stock pressure has migrated inland as buyers priced out of Lisboa and the Algarve hunt for absolute affordability, and as remote-work residency arrivals lengthen the radius of viable commuter zones around regional capitals.
The Centro region's +15.4% annual move sits against a backdrop of one of the country's lowest absolute price levels at €1,794 per m², the cheapest of the seven NUTS II regions. Castelo Branco, Portalegre, Bragança, Vila Real and Beja round out the five cheapest district capitals, all four-figure entries between €1,050 and €1,472.
Caution Signals Versus the Headline
The May tape lands in tension with idealista's own early-May read on transaction volumes, which flagged a moderation in both completed sales and the pace of new asking-price uplifts as families weighed Euribor's trajectory against listing prices. The Banco de Portugal's 27 May Financial Stability Report named residential property correction risk as one of the two macroprudential watchpoints for 2026, alongside climate shocks, and the supervisor's own residential price model put market overvaluation at around 30% for the most recent observation.
What the May figure does not yet capture is the impact of the Regime de Arrendamento Acessível Simplificado, scheduled to replace the 2019 Programa de Apoio ao Arrendamento on 1 September 2026, or any second-half cooling that would close the +10.2% headline gap versus the +6% to +8% range that several bank research desks have built into their 2026 base case.
