Spain has entered a new era of real estate transparency. The newly launched Notarial Housing Portal (Portal Estadístico de Notariado) provides official, deed-verified data from municipal to postcode level—finally giving the market the accuracy it deserves with real transaction prices. Free, transparent, and official, it allows buyers, sellers, and professionals to make decisions with far greater accuracy.
Why It Matters: A Powerful New Tool for Understanding the Market
The portal’s interactive maps and dashboards allow users to explore national, regional, provincial, municipal, and even postcode-level data. Filters let you break down results by property type, size, and transaction numbers. All figures are continuously updated and aggregated from notarised deeds, offering a clear, reliable snapshot of real market activity.
For Marbella, the Costa del Sol, and the rest of Spain, this represents an important shift in Spain’s real estate transparency . Agents, developers, analysts, and buyers can now work from real average prices enabling more precise valuations, smarter pricing strategies, and better-informed decisions across the industry.
What It Shows about Marbella
In the 12 months up to September 2025, the average real sale price in Marbella was €4,228/m², rising to €4,509/m² in the July–September quarter. Prices grew 12.59% during 2024.
These are true closing prices—not the higher asking prices you see on property portals such as Idealista, which reported about €5,400/m² for the same period.
A New Era of Transparency
The Real Estate sector has been waiting for Spain to catch up with other countries and now we have! Never before have we had access to such accurate, granular data—right down to individual postcodes within each municipality. This new level of transparency, made possible by the hard work of Spain’s Notary Council, marks a turning point in the availability, accessibility and quality of property market information in the country.
