Is Idealista legit? What our data says about fake listings
Yes, Idealista is a legitimate platform: it's Spain's most visited property portal, with more than 10.8 million users a month. But in Barcelona, 4.3% of the long-term rental listings we analysed over the last 30 days showed enough signs of fraud for us to block them. The company is real. Some of the people advertising on it are not.
That distinction is the whole answer. Idealista is a portal: agencies and private owners publish listings on it, and it doesn't own, visit or rent out the homes. So "is Idealista legit?" really means two things. Is the company trustworthy? Yes. Is every listing? No, and the risk is concentrated in one place: long-term rentals in the big cities.
Idealista, the company
Idealista was founded in 2000 by Jesús Encinar and is based in Madrid. It also runs property portals in Portugal and Italy. In 2024 the private equity firm Cinven bought a majority stake in a deal that valued the business at 2.9 billion euros. In September 2025, GfK DAM, the panel that measures Spanish online audiences, counted more than 10.8 million monthly users on Idealista, well ahead of Fotocasa (4.3 million) and every other property portal in Spain.
Searching and contacting advertisers on Idealista is free for tenants and buyers.
How many Idealista listings are fake?
Nobody outside Idealista can give an exact figure, and Idealista doesn't publish one. What we can share is what our own scanner sees. Prio scores every new Idealista listing it picks up against a set of fraud signals, and holds back the alert when the score crosses a threshold. Over the 30 days to 26 September 2026, this is how often that happened:
| Listings on Idealista | Analysed | Blocked as likely fraud | Share |
|---|---|---|---|
| Long-term rentals, Barcelona city | 4,556 | 195 | 4.3% |
| Long-term rentals, Madrid city | 5,337 | 145 | 2.7% |
| Long-term rentals, all of Spain | 40,093 | 822 | 2.1% |
| Homes for sale, all of Spain | 120,948 | 135 | 0.1% |
Three things stand out. Rentals are where the fraud is: listings for sale barely register. Barcelona's rate is higher than Madrid's and about double the national rental average. And the figure is a count of listings that crossed our threshold, not of confirmed scams.
How reliable is that threshold? We regularly check a sample of flagged and unflagged listings by hand. So far, every listing that scored above our threshold has turned out to be a scam, and we also find scams that score below it. The figures in the table above are a lower bound.
What this means in practice
At a rate of 4.3%, if you contact twenty rental listings in Barcelona, the chance that at least one of them is a scam is better than even. That's not a reason to avoid Idealista. It's a reason to check every listing before you send money or documents.
Warning signs of a fake Idealista listing
These are common patterns in the listings our system flags. Most flagged listings show several at once.
- A price well below the going rate for the neighbourhood. If a flat costs much less than similar ones nearby, find out why before you go any further. Our Barcelona rent price map shows what flats actually cost in each area.
- Only one way to get in touch. No phone number, or a phone number and nothing else. Real agencies and most owners are reachable in more than one way.
- A request for money before a viewing. Fotocasa's own advice is blunt: an owner who insists on payment before you can visit is almost certainly running a scam.
- A WhatsApp number written into the description. An attempt to move the conversation off Idealista, where the platform can't see it.
- The same phone number on unrelated listings. One "private owner" advertising several different flats, sometimes in different cities.
- A very short description with little detail. A couple of lines and nothing concrete about the flat.
- "I'm renting it for my son / sister / a friend." A story explaining why the person you talk to can't show you the flat themselves.
- An A energy consumption rating on a flat that isn't a new development. The top grade on an existing flat deserves a second look, and it's a detail fraudsters often fill in carelessly.
- A foreign phone number. Plenty of honest owners live abroad, but combined with other signs it's a reason to be extra careful.

Idealista vs Fotocasa vs Badi: who checks what?
None of the big platforms visits every property, so none of them can guarantee that a listing is real. Here is what each one says it does.
| Platform | What it says it does | How to report |
|---|---|---|
| Idealista | A quality team reviews listings and removes those it suspects are fraudulent. If you contacted a listing that is later removed as fraud, Idealista emails you to warn you. | Report form on every listing. Idealista says it checks every report. |
| Fotocasa | Validates advertisers by phone and moderates listings after they are published. | "Report" button under each listing, and a form if you have been scammed. |
| Badi | Lets users verify their profile and asks everyone never to pay or share bank details outside the platform. | Report a user or room in the app. Badi says it investigates every report. |
The common thread: all three moderate, and all three rely partly on users to report. Most checks happen after a listing is published, so a fake advert can be online long enough to reach you. Your own checks are the ones that count.
If you think you've been scammed
- Stop all contact and don't send anything else, including ID documents.
- Report the listing to the platform, using the listing reference.
- Call your bank immediately if you paid by transfer or card. The sooner you ask, the better the chance of stopping the payment.
- File a complaint (denuncia) with the police: the Policía Nacional, or the Mossos d'Esquadra in Catalonia. Keep screenshots of the listing and every message.
Frequently asked questions
Is Idealista safe to use?
Yes, as long as you treat every listing as unverified until you've seen the property. Idealista is a legitimate company and Spain's most visited property portal. The risk comes from some advertisers: in the 30 days to 26 September 2026, 4.3% of the Barcelona long-term rental listings we analysed showed enough fraud signals to be blocked. Never pay anything before a viewing.
How do you spot a fake listing on Idealista?
Look for a price well below the going rate for the neighbourhood, only one way to get in touch, a request for money before a viewing, a WhatsApp number in the description, the same phone number on unrelated listings, a very short description, a story about renting on behalf of someone else, an A energy rating on a flat that isn't a new development, and a foreign phone number. Most scams show several of these at once.
Can you get scammed on Idealista?
Yes. Idealista removes listings it suspects are fraudulent and lets you report any listing, but fake adverts do get published, mostly long-term rentals in the big cities. The usual scam asks for a deposit or the first month's rent before you've seen the flat. If you've paid, report the listing, contact your bank straight away and file a police complaint.
