CasaValidator: Buy in Spain

Alex Montesinos

About this app

Buying a home in Spain? Check its potential risks first: liens and debts in the land registry (nota simple), real versus advertised size, fair price and the condition of the property.

CasaValidator cross-checks official Spanish public data (Cadastre, Land Registry, ministries) with artificial intelligence and delivers a clear PDF report, with a risk score and recommendations, in minutes.

DISCLAIMER: CasaValidator is a private, independent service. It is not an official app, does not represent any government or public body, and is not affiliated with the Spanish Cadastre, the Land Registry or any ministry. Links to the official sources we use are listed at the end.

WHAT WE CHECK
• Land Registry extract (nota simple, Full plan): ownership, mortgages, seizures and other encumbrances.
• Real versus advertised size: we compare Registry, Cadastre and listing to spot differences.
• Estimated fair price: we tell you whether the asking price is within a reasonable range for the area.
• AI visual analysis: the AI reviews the photos for possible damp, wear or pending renovations and estimates their cost.
• Natural risks: flood zone (SNCZI) and radon zone (CTE DB-HS6) for the municipality.
• Surroundings: safety, nearby services and price trends.

HOW IT WORKS
1. Tell us which property it is and upload a few photos from the listing.
2. The AI cross-checks official data and analyses the images.
3. You receive your PDF report in minutes (the Full report, with the Land Registry extract, within 24 business hours).
