The most common scams in housing rentals
The modus operandi of real estate scammers is based on urgency and necessity. The most common scam is that of the supposed owner who resides abroad (for work or medical reasons) and requests a deposit or reservation payment to send the keys by courier.
Another widespread variant is the cloning of pages of recognized agencies or platforms such as Airbnb or Booking, sending fake payment links that perfectly imitate official banking gateways.
"No legal agency or legitimate owner will require you to transfer money before physically visiting the property and reviewing the contract."

If you notice any of these signs in an ad or conversation, stop all contact immediately:
Suspicious Patterns to Avoid
-
Abnormally low prices: Luxury flats in Eixample or Gràcia for €600 or €700. Unrealistic bargains in high-demand areas don't exist.
-
Inability to view the apartment: Constant excuses about keys being in another city, current tenants being sick, or unforeseen landlord travel.
-
Extreme urgency to collect: Pressure ensuring "there are 10 people waiting" and that you'll lose the spot if you don't transfer a deposit in minutes.
-
Untraceable payment methods: Request for money via Western Union, MoneyGram, prepaid cards, cryptocurrencies, or transfers to foreign accounts.
How to verify that the apartment and the landlord are real
Before making any disbursement, carry out these security checks:
- Request a Property Registry Extract: At the Property Registry you can check for less than €10 who the real owner of the apartment is and if it matches the person who is renting it to you.
- Requires the Certificate of Occupancy: Official document from the Generalitat certifying that the space is legally suitable for habitation.
- Check the agency's AICAT number: In Catalonia, professional real estate agents must be registered with the Register of Real Estate Agents (AICAT).
Golden rules for secure payments
Follow these non-negotiable principles when formalizing the bond or reservation:
Secure Payment Protocol
-
Always after visiting the property: Never transfer money for a property you haven't seen in person or through a trusted representative.
-
Matching Spanish bank account: The IBAN must belong to a registered banking entity, and the account holder must be the contract owner or the accredited agency.
-
Signed reservation document: Every financial payment must be backed by a document specifying the rental terms, amount received, and refund clause.
-
Deposit of bond at INCASÒL: The landlord is legally obliged to deposit your security deposit with the official body of the Generalitat (INCASÒL) and provide you with proof.
What to do if you have detected a scam or have been a victim
1. Contact your bank urgently: If you have just made a transfer, immediately ask your bank to stop or reverse it due to cyber fraud.
2. Report to the Mossos d'Esquadra or National Police: Provide all evidence: screenshots of the ad, WhatsApp conversations, emails, transfer receipts, and recipient account details.
3. Report the listing on the real estate portal: Notify the portal where you saw the listing (Idealista, Fotocasa, Habitaclia) so they can delete the ad and block the scammer's account.
Frequently asked questions
Is it legal to ask for money before I see the apartment?
No. Demanding payments to visit a property or to "hold your place in line" is a completely fraudulent practice. Property viewings are always free of charge.
How do I know if a real estate agency in Barcelona is trustworthy?
Check that the agency has a visible physical office, an AICAT registration number in Catalonia, and verifiable Google reviews from real clients.
What do I do if the landlord tells me to process the payment through Airbnb?
Beware. Scammers send fake links that mimic the Airbnb website to steal transfers. Airbnb does not manage long-term residential rentals outside its own official platform.
How much money is it normal to give as a reservation or down payment?
It is common to pay between €500 and 1 month's rent after the visit, always with a signed reservation document stating that the money will be returned if the owner rejects your profile.
