Frequently Asked Questions
What is PropDatos?
PropDatos is a curated directory of real estate data sources, APIs, and providers available in Spain. We compile technical details, pricing, access methods, and use cases to help developers and builders find the right data for their applications.
Is all this data really available?
Yes. Every source listed on PropDatos is a real, verified resource available to developers. We include official government datasets (Catastro, INE), commercial portals (Idealista, Fotocasa), and specialized providers. Availability and pricing vary by source.
Do I need to pay for all data sources?
No. Many sources are free or open-data (Catastro, INE, datos.gob.es). Others are freemium or commercial. We clearly indicate the pricing model for each source so you can plan accordingly.
Can I use this data for commercial applications?
It depends on the source. Government datasets like Catastro and INE typically allow commercial use under open licenses. Commercial portals like Idealista have paid API plans for commercial use. Always review the licensing terms for your chosen source.

Why Spanish Real Estate Data Matters
Spain is one of the most dynamic real estate markets in Europe, with growing demand for data-driven property analysis, automated valuations, and smart building management. Whether you are building a proptech startup, conducting market research, or developing urban planning tools, access to reliable real estate data is critical.
From the Cadastro (Spain's official land registry) to commercial property portals like Idealista and Fotocasa, the Spanish real estate data ecosystem offers a rich variety of sources for builders. Government open data portals provide cadastral boundaries, energy certificates, and building permits, while commercial providers offer real-time listing data, price indices, and market analytics.
PropDatos catalogs these sources to help you find exactly what you need — whether it is raw property data for machine learning models, API access for real-time integrations, or bulk datasets for market analysis.
Key Data Categories for Spanish Real Estate
Cadastral and Registry Data
The Catastro and Registro de la Propiedad are the foundational data sources for property ownership, boundaries, and valuations in Spain. The Catastro provides open access to cadastral references, property areas, and geographic coordinates through both a web portal and INSPIRE-compliant WMS/WFS services.
Property Market Data
Real-time and historical property listing data from portals like Idealista, Fotocasa, and Pisos.com enables market analysis, price tracking, and automated valuations. Several commercial API providers aggregate this data into structured feeds for proptech applications.
Building and Energy Data
Spain's building stock data, including energy performance certificates (CEE), construction permits, and building condition assessments (ITE), are increasingly available through government open data portals and specialized providers.
