Find and analyze BOE auctions
in seconds

The BOE Auction Portal is a flat listing: no map, no valuations, no profitability calculation, no charge analysis. MapaSubastas collects the data from the BOE, the Tax Agency and the Social Security portal, geolocates it and cross-references it with the Cadastre, Street View, market valuations and court data so you can discard what is not worth it and find the opportunity in seconds. It is a professional data intelligence tool for investors who value their time.

The difference is massive. With ChatGPT or any generic AI, you do all the work: find the auction, download documents, copy and paste the relevant information, explain the legal context of each case… and still risk it making up critical data. Every auction is different — procedure type, jurisdiction, prior charges, occupancy status — and a generic AI has no access to this data nor understands its legal specifics. MapaSubastas is radically different: our AI engine already has integrated data from the BOE, the Cadastre, the edict, and the charge certification for each auction. It automatically analyzes all documentation and generates a structured legal report in seconds, without you having to upload or explain anything. It's the difference between a generic assistant and a professional tool built specifically for real estate auction investment.

In auctions, mistakes are expensive. The Pro Plan gives you our automatic AI analysis of charges and land registry notes for every active auction, ready to consult instantly without spending credits. And if you find an auction without prior analysis, you can upload the land registry note yourself for our AI engine to generate the Legal Report instantly with your included credits. You also get Cadastre PRO, Urbanism PRO (5 layers: land use classes, flood zones, protected areas, coastlines, and drovers' roads), court data (CGPJ), and the agency radar. If you're just getting started, the Personal Plan already includes Comparables, Profitability Calculator with saved scenarios, valuations, Area snapshot, and assignment transfer hot deals.

No, you don't need to subscribe. You can buy individual credits from just €2 and use them to generate AI legal reports for the auctions you're interested in, with no commitments or lock-in. It's the fastest way to try our technology with minimal investment. If you later want full access to all tools, you can always switch to a plan, but to start analyzing auctions with artificial intelligence, a few credits is all you need.

Yes, all prices shown on our website include VAT. No hidden costs or surprises at checkout.

We don't use inflated "listing" prices from real estate portals. We use automated valuation models (AVM) from Cassandra AI and actual closing data. Our profitability calculator (included from the Personal Plan onwards) lets you deduct Transfer Tax, renovations, and preferential charges to estimate your real net margin and save the scenario to fine-tune it later.

Our specialized artificial intelligence engine processes in seconds what a professional takes hours to review, and does so with very high accuracy. However, it does not replace the judgment of a specialized lawyer or advisor: it's a screening and preliminary analysis tool that allows you to instantly discard unviable operations and focus your resources on those that are worthwhile. For opportunities that pass that filter, at MapaSubastas we offer complementary professional services such as on-site property visits, personalized legal advice, and comprehensive support throughout the entire award process. This way you cover quick analysis with technology and deep analysis with professionals specialized in auctions.
