- We only count a match once we're confident it's genuinely the same property; we'd rather under-count duplicates than wrongly merge two different homes.
- The teal wedge shows the exclusive share; the grey track shows the duplicate, multi-agency share.
- Areas with very few listings on the market are left out, since a handful of listings can swing the percentage wildly.
In plain terms: this page shows exactly how many properties are exclusive (marketed by one agency on one website only) and how many are duplicate listings, the same property showing up on 2, 3, 4, or 5+ different agency and property websites at once. If you see the same home on two different websites, that's a duplicate listing from a buyer's point of view, even though each website may be showing it through a different agency.
Worth bearing in mind: it's common for an owner to list the same property with more than one agency at once, and what looks like a single "agency" is sometimes really a network or syndicate of several separate agencies working together and cross-posting the same listing under different names. Between the two, one physical property can end up appearing as several separate listings spread across many different websites. The figures on this page reflect that reality rather than correcting for it: what follows is a breakdown of the listings currently live on the market in Mallorca, exclusive and multi-agency alike.
How many websites is each property on? · island-wide
Based on 39,743 listings. A property listed on 2 or more websites is a duplicate listing from a buyer's point of view, even if each site shows it via a different agency. Collapsed to 19,170 unique properties, 90% of which sit on a single website. That is a different measure, not the same share counted twice: the figures above count listings, this one counts properties.

How thorough do you need to be?
Set your search and we'll tell you what share of matching properties are exclusive to a single website, plus which portals (Idealista, Fotocasa, and the rest) are actually showing them.
What this means if you're buying
Most listings on this page are exclusive, marketed by a single agency, on a single website. That has a direct, practical consequence: your dream property is very unlikely to be sitting on every portal you check. To see a genuinely complete picture of what's on the market, you'd need to search across dozens, if not hundreds, of individual agency websites, not just the handful of big property portals most buyers start with.
Even the largest portals, the likes of Idealista and Fotocasa, only ever show a slice of the total open market. A listing that's exclusive to one small local agency, on that agency's own website, may never appear on a major portal at all. Relying on a single site, however big its name, means missing a meaningful share of what's genuinely for sale.

Frequently asked questions
It means we're confident the property is being marketed by a single agency, on one website only. "Multi-agency" means we've matched the same property listed by more than one agency, or on more than one property website, at the same time; in other words, it's a duplicate listing from a buyer's point of view, even though each website may show it via a different agency.
We compare listings on things like location, size, price, photos and description to identify strong matches; we only count a property as multi-agency (a duplicate listing) once we're confident it's genuinely the same home, not just similar. That's why we call this "firm-confidence" matching: we'd rather under-count duplicates than wrongly merge two different properties.
For a buyer, a property listed on several sites at once suggests it's open-market and you're one of several routes to the seller. For a seller, exclusive listings are sometimes marketed more heavily by a single agency, while multi-agency listings can mean wider reach but also more competing enquiries through different channels.
It often reflects local market practice: some areas or price brackets are more commonly handled through sole-agency arrangements, while in others it's standard for several agencies to market the same property simultaneously.
It's recalculated from the live listings currently on Mallorca's property websites, so the split shifts as listings are added, removed, or picked up by additional agencies.
