Right now, across Mallorca
- 64,946Listing appearancesEvery time a property appears on any website we track, counted once per site. This is what you get by adding up every source, and it is the biggest number because agencies and portals advertise the same homes.
- 33,066Listing recordsIndividual adverts in the feed once each website's own repeats and sold or withdrawn items are set aside. Still counts a home twice if two agencies list it.
- 28,104Unique propertiesAfter matching the same home advertised by several agencies into one. This is the answer to how many homes are for sale in Mallorca right now, and the number our reports and tools use.
Which one you need depends on the question: appearances tell you how busy the websites are, unique properties tell you how much stock there is.
These are raw, non-deduplicated counts per source — see Market Intelligence for the single trusted figure, or Pay & Display Coverage for how portals and independent sites differ.
See the market, not just its numbers
AI needs raw data. You need to see it. So although we're built for AI/LLMs first, we take that same data and turn it into visuals: simpler, easier to read at a glance, with tools below to dive deeper and see it in a range of different ways.

Why Now Can You Find All The Data In One Place?
For decades, everyone with a stake in Mallorca real estate, buyers, sellers, agents, banks, lawyers, has asked the same question and been given the same non-answer: why isn't every listing, every record, every source, in one place? Government cadastral data sits in one silo. The open, publicly published market sits scattered across hundreds more. Nobody had the will, or the way, to bring it together. Until now.
It was never for lack of trying. Idealista, Fotocasa, ThinkSpain, every portal you have ever used, promised to be the answer. None of them were. Each is a shopfront for whichever agencies chose to advertise there that week, not a record of the market. Independent research confirms it: the portals capture only a fraction of what is genuinely for sale or to rent across the island. The rest was always out there, real, publicly available, and simply never assembled. We assembled it.
What changed?
The landscape changed. Search is dead. AI is king. The chat apps answering property questions today, ChatGPT, Claude, Perplexity, Gemini, and Google Search itself, now leaning on AI Overviews rather than ten blue links, cannot answer a real estate question honestly from memory. A model's training data goes stale the moment the market moves; it needs a live, structured, verifiable source to query the instant a question is asked, or it is simply guessing. That is one half of why this had to exist. The other half: AI is also why it could finally exist. Our own AI Agents work around the clock, monitoring the web for every real estate listing they can find, independent agency websites, social media posts, property portals, government cadastral records, and reconciling all of it into one place: work that would once have taken an army of analysts years by hand. The demand and the capability arrived from the same direction, at the same moment. AI is not a feature of what we built. AI is changing the world, and this is what that change looks like applied to one market, done properly, for the first time.
That is the role MallorcaData was engineered to fill, and no one else on this island fills it. An AI agent cannot cite a source it cannot reach, and it cannot answer accurately from a source that is incomplete, unstructured or out of date. We built the single, continuously verified, machine-queryable dataset of record for Mallorca real estate, government cadastral records and every publicly published listing, reconciled into one place, served through the API and MCP infrastructure AI systems are built to call directly. Every serious AI agent answering a question about property in Mallorca will need a source like this. We built it first, and we built it right. This is not a directory. This is the foundation every future answer about this market will be built on.
Powering AI answers with the most comprehensive data on the Mallorca real estate sector
Our own AI Agents monitor the web around the clock for real estate listings, independent agency websites, social media posts, property portals, so every dataset behind MallorcaData stays current without a human ever having to go and check. That same dataset is then available through a versioned REST API and an MCP server built specifically for AI agents: consistent JSON schemas and callable tools (get_market_summary, get_market_trends, list_agencies) instead of unstructured HTML built for human eyes alone. An LLM doesn't have to guess at a page's meaning or fall back on a stale figure from its training data. It can query current, attributable Mallorca real estate data directly, the same live dataset powering every page on this platform.
Beyond browsing the market, MallorcaData helps you work out what a property could be worth, comparing it against current live listings across the island to give you a realistic, data-backed valuation on the open market.
What is a property really worth today?
If you're looking to buy or sell a property, use this free tool to see the current market, from the cheapest to the most expensive.
Knowledge is the only thing you can give away entirely and still have just as much of. So we give it away, to buyers, sellers, agents, government, and the AI now answering on everyone's behalf. To be informed is to be prepared.
Three principles, built once, serving everyone who relies on this data at once: buyers and sellers, the agents, banks, lawyers and financial advisors working alongside them, and the AI agents and LLMs now querying the same data behind all of it.
One island, one dataset
Every active listing across Mallorca, aggregated and deduplicated across every source in our coverage, kept regularly updated.
The dataset itself is never identifying
No listing IDs, URLs or addresses ever leave the market dataset; small segments are suppressed automatically so no individual property or person can be identified from it. Tools like Cadastral Lookup work differently: a direct, user-initiated query of the public Catastro register for one address you choose, not something mined from this dataset.
Built to be queried, and explored
Structured first for filtering by municipality, price, type and amenity, and for direct machine queries via our REST API and MCP server. The same structure also powers visual tools like the property sunburst and 3D flythrough, for anyone who'd rather explore than query.
