Buy property in Spain with confidence — and without the horror stories

Why independent legal advice is essential

The Spanish property market is vibrant and competitive, especially along the Costa del Sol, in Madrid, and in the Balearic Islands. Every year, approximately 87,000 properties are sold to foreign buyers — more than in any other European country except France. The appeal is obvious: warm climate, strong infrastructure, an excellent healthcare system, and a quality of life that is hard to match.

But the market has structural features that create serious risk for buyers who are unfamiliar with Spanish law. Estate agents work for the seller, or in many cases operate under a dual agency arrangement where they nominally represent both parties while having a financial interest exclusively in the deal completing. They are not qualified to advise on title defects, planning compliance, or tax obligations. “The paperwork is all in order” is an estate agent phrase, not a legal opinion.

Spain’s property law is broadly protective of buyers, but only if you use it. Defects in title, planning irregularities, and undisclosed debts are not the seller’s agent’s problem to discover — they are yours to find, and the standard remedy once the title deed has been signed is expensive litigation that will take years. The Tribunal Supremo has repeatedly confirmed that the principle of caveat emptor applies in the context of defects that a diligent buyer would have discovered with proper investigation.

This guide walks you through every stage of buying property in Spain as a foreigner: from the first practical steps (getting your NIE) through due diligence, the private contract, the notary, and post-purchase obligations. We include a full cost breakdown by autonomous community, an explanation of the mortgage process for non-residents, and the most common mistakes that foreign buyers make.

Step 1: Get your NIE before you search

The Número de Identificación de Extranjero (NIE) is your Spanish tax identification number. Every legal transaction in Spain — signing a purchase contract, opening a bank account, paying taxes, obtaining a mortgage — requires a NIE. Without one, you cannot sign the title deed before a notary.

Getting your NIE takes longer than most people expect. The two options are:

Option A: Apply at the Spanish Consulate in your home country. You submit a completed Modelo EX-15 form, your passport (and a photocopy), and a fee of approximately 10 euros. You must also explain the purpose of the NIE (property purchase is a valid reason). Processing time: 2–8 weeks depending on the consulate. Some consulates require an appointment that can take weeks to obtain.

Option B: Apply in person at a Spanish Comisaría (police station) or Foreigners’ Office if you are already in Spain. You need Modelo EX-15, your passport, a photocopy, the fee, and documentation justifying your need for the NIE (a signed purchase contract or a letter from a Spanish notary confirming an intended transaction is usually sufficient). Processing time: same day to 2 weeks depending on location. The main limitation is that you must be physically present in Spain to apply, and the appointment system in Madrid and Barcelona can be extremely congested.

BMC can apply for your NIE by power of attorney, attending on your behalf at the designated office in Spain so that you do not need to make a special trip. This is a standard part of our property purchase service for clients based outside Spain.

Practical tip: Apply for your NIE as soon as you have identified a property you intend to pursue. Do not wait until the contract is ready. Many transactions have been delayed or lost because the buyer did not have a NIE when the seller wanted to proceed.

Step 2: Open a Spanish bank account

You will need a Spanish bank account to:

• Pay the purchase price at the notary (the standard method is a banker’s draft (cheque bancario) drawn on a Spanish bank in the name of the seller)
• Pay transfer tax, notary fees, and Land Registry fees post-completion
• Set up direct debits for utility bills, community charges, and local property tax (IBI) after you take ownership

Opening a bank account as a non-resident foreigner is possible but requires specific documentation. The major Spanish banks — Santander, BBVA, CaixaBank, Sabadell, Bankinter — all have cuentas de no residentes (non-resident accounts) designed for this purpose.

Required documents typically include: valid passport, NIE (some banks will open the account with a pending NIE application reference), proof of address in your home country (utility bill or bank statement, usually translated), and a completed bank account application form.

If you are an EU national, the process is generally straightforward. Non-EU nationals may face more scrutiny, particularly for large account deposits, due to anti-money-laundering requirements under Spanish Ley 10/2010. Banks will ask for documentation of the source of funds — salary records, investment account statements, sale proceeds from another property — which should be prepared in advance.

Processing time: 1–5 business days once documents are accepted. Some banks offer a faster process if you have an introduction from a private banker or if your funds are above a threshold that qualifies you for private banking services.

Step 3: Search and offer

The Spanish property market operates differently from the UK, Netherlands, or US markets that many foreign buyers are familiar with.

Multiple agencies: The same property may be listed with several different agencies, each potentially advertising it at a different price. There is no single MLS-style database. The practical implication is that contacting the seller’s agent directly (or finding the listing on portals like Idealista, Fotocasa, or Rightmove Overseas) does not necessarily give you the best commercial position. An independent advisor who understands the local market can identify the actual asking price, the realistic negotiation range, and whether the seller has any urgency.

Negotiation: Prices in Spain are typically negotiable. The degree of negotiation depends on the property type, location, and seller’s motivation. In coastal resale markets (Costa del Sol, Costa Blanca) a 5–15% reduction from asking price is common. In the most competitive segments of the Madrid or Barcelona apartment market, properties may sell at or above asking price. Get local intelligence before you submit any offer.

Verbal offers: A verbal offer, even if “accepted” by the seller, has no legal weight in Spain. The transaction does not become binding until a written contract is signed. Do not transfer any funds based on a verbal understanding.

Step 4: Legal due diligence — the most important step

Due diligence must be completed before you sign any private contract or hand over any deposit. This is where most buyers make their most consequential mistake: signing the arras contract first and hoping the due diligence comes back clean.

BMC’s due diligence covers:

Nota Simple (Land Registry extract)

The nota simple informativa shows the registered owner(s), the legal description (surface area, cadastral reference), all mortgages, charges, liens, and pending litigation annotations. Always obtain a fresh nota simple immediately before signing any contract, and again before the notary appointment — charges can be registered at any time. The registered surface area may differ from the physical property; this discrepancy must be regularised before or at purchase.

Catastral, planning, and debt checks

The Catastro holds the fiscal reference, registered area, and valor catastral. It must match the Land Registry — discrepancies indicate irregularities. We also verify planning compliance with the relevant Ayuntamiento: an extension built without a licencia de obras cannot appear in the title deed, may block a mortgage, and creates a problem at resale.

Beyond the nota simple mortgages, properties can carry community debts (claimable against the new owner for the current and prior year), IBI arrears (four years of exposure), and unpaid utility contracts. We obtain all relevant certificates and verify the seller has full legal capacity to sell — including court-order checks and confirmation that all co-owners are participating.

Step 5: The earnest money contract (Contrato de Arras)

Once due diligence is complete, you enter the binding private contract phase via a contrato de arras. The most important type is arras penitenciales (Article 1454 Civil Code): the buyer pays a 5–10% deposit; if the buyer withdraws, the deposit is forfeited; if the seller withdraws, they return double the deposit. This protection applies only if the contract explicitly uses the Article 1454 classification — an undifferentiated deposit may not carry the double-return obligation. BMC reviews or drafts all arras contracts to ensure correct classification, clear conditions precedent, and a realistic completion timeline.

Step 6: Non-resident mortgages — financing your purchase

Foreign buyers can obtain mortgages from Spanish banks, but on different terms from resident mortgages. Maximum LTV for non-residents is 60–70% of the lower of purchase price and the bank’s tasación (valuation) — so plan for liquid funds of 40–50% of the property value (deposit plus acquisition costs of 10–12%). Euribor-linked rates in 2025 are 2.5–3.5% plus bank margins of 0.75–1.5%; fixed-rate products are also available. Required documentation includes: passport and NIE, 2–3 years of home-country tax returns, bank statements, employment or business accounts, and a credit report. Allow 8–12 weeks from mortgage application to notary completion. International banks (HSBC International, Barclays International) offer cross-border products worth exploring for purchases above €500,000.

Step 7: The notary process

In Spain, the transfer of real property is completed by the execution of a escritura pública de compraventa (public title deed) before a Notario — a state-appointed legal official. The notary is not a party to the transaction and does not represent either buyer or seller; they are a public official who authenticates the signatures and confirms the deed’s compliance with Spanish law.

Who chooses the notary: In practice, the buyer has the right to choose the notary (the party paying the notary fees). In many transactions, the estate agent or the seller’s solicitor proposes a notary and buyers accept without realising they can choose. Choosing your own notary, or one that BMC has an established relationship with, is always preferable.

What happens at the notary appointment:

1. The notary reads the deed aloud (or provides a summary for non-Spanish speakers). If you do not speak Spanish, a sworn interpreter must be present, or the notary must provide an official translation. In practice, many coastal notary offices have bilingual staff, but you should not rely on this.
2. The buyer pays the seller. Payment is made by official banker’s draft (cheque bancario) drawn on a Spanish bank in the seller’s name, or by bank transfer in certain circumstances. Cash payments above 1,000 euros are prohibited.
3. If there is a mortgage, the lender’s representative (a bank employee or the bank’s own solicitor) also attends, and the mortgage deed is executed simultaneously with the title deed.
4. Keys are exchanged.
5. Copies of the executed deed are provided to both parties. The original (protocolo) remains with the notary.

Before the appointment: BMC reviews the draft deed (the minuta) sent by the notary’s office 24–48 hours before the appointment. This review checks that the deed accurately reflects the agreed terms, that all mortgage charges on the property have been cancelled (shown by notarised cancellation deeds or the seller’s solicitor’s undertaking), and that the correct purchase price and taxes are reflected.

Step 8: Taxes on the purchase — full breakdown by autonomous community

The tax burden on a Spanish property purchase is significant and varies by region. The tax is payable within 30 days of the title deed being signed.

Resale properties: Impuesto sobre Transmisiones Patrimoniales (ITP)

ITP is a regional tax levied on the transfer of existing (resale) properties. Each autonomous community sets its own rate:

Key points: Madrid’s 6% rate is the lowest of the main autonomous communities and contributes to the capital’s attractiveness for investment property. The Balearic Islands (Ibiza, Mallorca, Menorca) apply a progressive scale: 8% on the portion up to 400,000 euros, 9% from 400,001–600,000 euros, 10% from 600,001–1,000,000 euros, and 13% above 1,000,000 euros, making it the most expensive major region for high-value purchases.

New-build properties: IVA + AJD

New residential properties are subject to:

• IVA (VAT): 10% of the purchase price (or 4% for officially designated affordable housing — vivienda de protección oficial)
• Impuesto sobre Actos Jurídicos Documentados (AJD / stamp duty): 0.75–2% depending on the autonomous community, applied to the full deed value

Total tax on a new-build: approximately 11–12% in most regions. Note that the IVA is charged by the developer and cannot be recovered by a private buyer (it is recoverable only if you are purchasing for business use under a VAT-registered entity).

Additional acquisition costs

Total acquisition cost rule of thumb: Budget 10–15% of the purchase price above the headline price for all taxes and fees on a resale property, or 12–15% on a new build. For mortgage purchases, add a further 1–2%.

Step 9: Land Registry registration

Completion at the notary does not immediately transfer legal title in the public record. The executed deed must be presented to the relevant Registro de la Propiedad (Land Registry) for registration. Until registration is complete, the transaction is not fully protected against third-party claims.

In practice, the notary transmits a telemático (electronic) copy of the deed to the Registry within hours of signing, and this submission creates a asiento de presentación (presentation entry) that protects the buyer’s position from the moment of submission. Physical registration — the formal updating of the Registry record — typically takes 10–30 days.

The Land Registry fees are paid at registration, calculated on the deed value. BMC handles the presentation, follows up on the registration, and obtains the final certified extract confirming the property is registered in your name.

Step 10: Post-purchase obligations for non-resident owners

Owning property in Spain as a non-resident creates ongoing compliance obligations. Even if your property sits empty, you must file an annual Modelo 210 on deemed rental income: 1.1% of the valor catastral (or 2% if not revised since 1994), taxed at 19% for EU/EEA residents or 24% for non-EU nationals. Deadline: 31 December of the following year. If you rent out the property, quarterly filings are required within 20 days of each quarter-end. EU/EEA residents may deduct mortgage interest, IBI, community fees, and management costs; non-EU residents pay 24% on gross income with no deductions.

Additional obligations: IBI (local property tax, 0.4–1.1% of cadastral value, paid by direct debit); community fees (gastos de comunidad, €50–500/month depending on facilities); and potential plusvalía municipal joint liability if the seller fails to pay.

Step 11: The 3% withholding on sales by non-residents

This rule catches many buyers by surprise. When a non-resident seller sells Spanish property, the buyer is legally required to retain 3% of the purchase price from the payment and remit it directly to the AEAT (Spanish Tax Agency) within one month of completion, using Modelo 211. This 3% is a payment on account of the seller’s Spanish capital gains tax liability.

The seller can subsequently claim a refund of any excess via Modelo 210 (capital gains). The risk for the buyer who fails to make the withholding and remittance is direct personal liability for the amount that should have been withheld.

If you are buying from a seller who is a Spanish resident, the withholding does not apply. The seller’s residence status must be confirmed — not assumed — before the notary appointment.

Due diligence for off-plan purchases

Off-plan purchases carry additional risks: developer insolvency, construction delays, and planning problems. Under Spanish law, developers must provide individual bank guarantees or insurance policies for every stage payment. Always verify the developer holds a valid licencia de obras, that guarantee documents name you specifically as beneficiary, and that the memoria de calidades (specification) is legally attached to the contract. Never rely on the developer’s assurance that the guarantee is “in place” — buyers without individual certificates faced catastrophic losses in the 2008–2012 crisis and in smaller insolvencies since.

Common pitfalls for foreign buyers

1. Signing the arras contract without completing due diligence. Once you sign and pay the deposit, your protection is limited to recovering double the deposit if the seller withdraws. If you discover a serious legal problem after signing, you may face choosing between losing your deposit and proceeding with a problematic purchase.

2. Relying on the estate agent’s recommended solicitor. Many estate agents in tourist areas refer buyers to a solicitor with a financial relationship to the agent. Your legal advisor must be instructed by you, paid by you, and answerable exclusively to you.

3. Not confirming the seller’s mortgage is formally cancelled. A mortgage discharge requires a notarised cancellation deed and Land Registry registration — “covered by the proceeds” is not the same as cancelled. We have seen buyers face claims from the seller’s bank after completion.

4. Ignoring the community of owners. Request the last three years of community meeting minutes and accounts before signing. This reveals deferred maintenance, unpaid extraordinary assessments, and disputes that become your liability at purchase.

5. Assuming the surface area is correct. The nota simple area, catastro area, advertised area, and physical area routinely differ. You pay per square metre — precision matters.

6. Failing to file Modelo 210. The AEAT systematically cross-references property ownership records with tax filings. Undeclared years generate interest at 3.75% per year plus 5–20% surcharges depending on timing of voluntary disclosure.
