Rental Scams in Spain: How to Spot Fraud on Idealista & Fotocasa

How often can you encounter scammers when searching for housing in Spain? The short answer: if you are searching actively, you will likely face them at least once.

I went through this myself and remember well that nasty feeling of doubt: what if this is the norm in Europe, what if this is how it should be? To save you time and money on paying for "thin air," I decided to collect the main schemes used by local scammers.

Below is a breakdown of how to spot a trick as early as the first message and what you definitely should not fall for.

How to Spot Scammers on Idealista and Fotocasa: 4 Main Schemes

Fraud on Idealista or in Facebook groups is no longer an accident; it is an entire industry. Everyone has one main goal: to force you to transfer a "deposit" before you even see the apartment or the landlord in person.

The "Remote Landlord" Scheme

The most common scenario involves listings for apartments with high-end interiors and prices 20–40% below the market rate. The scammer usually introduces themselves as an "engineer," "doctor," or "former expat" and claims to live in another country (Germany, Greece, UK) and cannot show the apartment personally.

• They do their best to move you from the Idealista messenger to WhatsApp — it is harder to get banned there.
• Then they report "high demand" and the need to pay a deposit to confirm the seriousness of your intentions.
• The victim is sent a link to a phishing site that looks visually identical to Booking.com or Airbnb. It is claimed that the platform will act as a guarantor of the transaction, hold the money in "escrow," and return it if you do not like the apartment after receiving the keys by courier.

Subletting Fraud

Another type of crime involves illegal subletting. A current tenant who has access to the apartment posts an ad in their own name, posing as the owner or their representative. They collect deposits and the first month's rent from several people at once, set a move-in date for a week later — and disappear.

Upon arrival, it turns out that they had no right to rent out the apartment, and the real owner demands immediate eviction. If the contract is not officially registered, the tenant has almost no legal protection in such cases.

Agency Tricks: How They Try to Charge a Commission Bypassing the Law

Since Ley 12/2023 por el derecho a la vivienda, article 20.1 of the LAU puts agency fees and the cost of drawing up the contract on the landlord — even when you were the one who asked the agency to find you something. The sentence that usually ends the argument is "Los gastos de gestión inmobiliaria corresponden al arrendador, artículo 20 de la LAU".

There is one exception, and it matters: article 20 sits in Título II of the LAU, which governs arrendamiento de vivienda — your permanent home. A seasonal contract (alquiler de temporada) falls under Título III, where the agency may still charge the tenant. That is exactly why you are sometimes offered a seasonal contract for a flat you plan to live in for years. Two things narrow the gap. Article 20.1 only reaches contracts signed from 26 May 2023, so an older one is governed by the old rules. And Catalonia closed the loophole outright: a regional law in force since 1 January 2026 applies the housing rules on deposits, guarantees and rent to seasonal contracts signed there. It has been challenged before the Constitutional Court and has not been suspended. Everywhere else, consumer associations are still fighting the practice and it is not settled. Meanwhile realtors show incredible ingenuity to make you pay anyway.

Usually, it looks like this: you found the apartment yourself, but the agent demands "one month's rent + VAT" for:

• "Information services" or "search service" (which you did not order).
• Drafting the contract or changing the name on the electricity bills.
• Simply as a "reservation fee" that does not go toward the rent.

Contract Type Manipulation

The use of 11-month contracts has become a common practice to bypass the strict framework of the Housing Law. Landlords impose such agreements even on those who plan to live in the apartment for years. The main problem for a relocated person is that after 11 months, the owner may choose not to renew the contract or significantly raise the price, whereas with a "habitual" (permanent residence) contract, the tenant has the right to automatic renewal for up to 5 or 7 years.

Checking the Apartment Before Signing

Ownership Verification and Legal Check (Nota Simple)

If you have decided that the apartment suits you — do not rush to take out your card. First, you need to make sure that the person in front of you actually has the right to rent out this property. For this, Spain has the Nota Simple — an extract from the Property Registry. What is important in it:

• The name in the extract must match the name in the contract. If they tell you "it's my brother's apartment," demand a power of attorney (poder).
• You can order a Nota Simple yourself at registradores.org, the official site of the Colegio de Registradores. The official fee is 9.02 € plus IVA — 10.91 € in total, as of September 2026. Intermediary sites that look like the registry and charge several times that turn up regularly among the first results for "nota simple online"; go straight to registradores.org.
• If the agent or owner refuses to provide the address or cadastral number for this check — turn around and leave. In Spain, this is public information; there is no reason to hide it.

The Registration Number on a Short-Term Flat

Your first month in Spain is usually a furnished flat booked on a platform, and that has a check of its own — one whose legal ground shifted in 2026. Real Decreto 1312/2024 introduced a nationwide Número de Registro de Alquiler from 1 July 2025, without which a short-term listing was not supposed to stay online. Over May and June 2026 the Supreme Court annulled the core of that decree — the register, the registration procedure and the verification duty are all marked "Anulado" in the consolidated text — on the grounds that the state had stepped into regional competence. A state number is no longer a condition for listing, and there never was a public way for a guest to check one, so any 2025 guide that tells you to look it up is out of date on this point.

What the rulings never touched is the regional tourism registers, and that is where an actual check is still possible. Every comunidad keeps its own, in its own format, and the rules differ more than most guides admit:

• Comunitat Valenciana — numbers look like CV-VUT1234567-A, with the province letter at the end (A Alicante, V València, CS Castelló). Quoting the number in any advertising is compulsory here, and you can check it yourself in the regional register — by number, cadastral reference or municipality, though not by address.
• Andalucía — numbers look like VUT/MA/00123 (older ones start VFT/). Its register search is the friendliest of the three: you can look a flat up by street, not only by number.
• Comunidad de Madrid — numbers look like VT-12345, and here two things are commonly got wrong. There is no public search form, only a downloadable register file. And the rule that required the number in advertising was struck down by a court and removed in 2019, so in Madrid a listing without a number is not by itself an offence or a sign of trouble.

Do not mix this up with the previous section. An alquiler de temporada under Título III of the LAU is not a holiday let and needs no tourism number; there the thing to look at is the causa de temporalidad — the reason for the fixed term — that the contract itself has to state.

Home Checklist: What to Check in a Spanish Apartment Before Signing the Contract

During the physical inspection of the apartment (visita), relocators often pay attention only to aesthetic aspects, missing technical details that can significantly affect the cost of living and comfort.

Power Capacity (Potencia)

Ask how many kW are in the contract. Where the widely-quoted 3.3 kW comes from is an old voltage: it was the 15 A step back when the grid was 220 V. At today's 230 V the same step is 3.45 kW, and the neighbouring common ones are 4.6 kW and 5.75 kW. Since 2018 a home with a smart meter can actually contract any figure in steps of 0.1 kW up to 15 kW, but those classic rungs are still what you will be offered. At 3.45 kW the meter trips the moment the air conditioner and the washing machine run together. The number is in the electricity contract, which as the incoming tenant you usually sign yourself, so ask the landlord what it is. Raising it needs a boletín eléctrico (CIE) from an electrician, and in an older building the wiring does not always allow it.

Mold and Windows

Many regions of Spain have high humidity, especially in coastal cities. Check what you might have to deal with for the coming years:

• You should carefully inspect the corners of the rooms, the areas behind wardrobes, and around window frames for black mold spots (moho).
• Single-layer aluminum frames do not retain heat well and do not insulate noise. The presence of double-glazed windows is a significant advantage.

Noise and Surroundings

Spanish urban culture is known for being noisy. Try to visit the house in the evening or on weekends. A cute bar under the window at 14:00 can turn into hell at 22:00 if you work from home or simply value peace.

Deposit and Condition Report Upon Move-in

The Urban Leasing Law (LAU) sets clear boundaries:

• Mandatory deposit: 1 month's rent for residential housing.
• Additional guarantees: Cannot exceed 2 months' rent for long-term contracts.

To guarantee the return of the deposit, it is necessary to draw up a detailed inventory (inventario) with photos of all defects: scratches on the floor, chips on furniture, the condition of appliances. This document must be signed by both parties and attached to the contract.

That inventory is the lever; article 36.4 of the LAU is what it works against. Once you hand back the keys the landlord has one month to return the deposit, and after that the outstanding amount accrues the statutory interest (interés legal del dinero). Quote the article by number when you write — it changes the tone of the reply.

Action Plan for Finding Housing

1. Temporary Housing (First 2–4 weeks): Do not try to rent long-term housing remotely. The risk of losing funds is much higher than the potential benefit. Use Booking.com or Airbnb to rent housing for the first month. It will be more expensive, but these platforms ensure a refund if the housing does not match the description. Use this time to obtain your NIE (foreigner identification number) and open a Spanish bank account, which is critical for signing a contract and paying utility bills.
2. Active Search and Filtering Ads: Use the Idealista and Fotocasa portals, but with extreme caution. Ignore ads where the owner is "away" or asks for an advance payment.
3. Viewing and Checking Documents: Remember the Nota Simple and be sure to order it yourself before paying a deposit. Ask the owner or agent to show their ID (DNI) and compare the details with the contract. Check the water (pressure and temperature), gas, electricity, and for the presence of mold. Ask about the type of heating (gas is usually cheaper than electric).
4. Signing the Contract and Payment: Insist on the "Arrendamiento de Vivienda" (habitual) type instead of "Uso distinto de vivienda" (seasonal) if this is your primary place of residence. Transfer money only via bank (transferencia bancaria). Keep the confirmation of the transfer — in Spain, this has the force of legal proof of payment. Arrange for a change of ownership (cambio de titularidad) for electricity and water contracts. This will allow you to control the bills and avoid the debts of previous tenants.
