The Complete Foreign Buyer’s Guide to Purchasing Property in Spain

There is a particular kind of clarity that comes to people who have decided — really decided — to buy a property in Spain. The noise of the decision fades, replaced by something quieter and more purposeful: the desire to understand the process, to get it right, and to move forward with confidence. If you have reached that point, this guide is written for you.

Buying property in Spain as a foreign national is entirely straightforward — thousands of international buyers complete the process every year, many of them on the Costa del Sol. But like any significant transaction in an unfamiliar legal system, it rewards preparation. The buyers who navigate it most smoothly are those who understand the steps before they take them.

What follows is a comprehensive, honest and practical guide to the entire process — from your first viewing to the moment you receive the keys to your new home.

Step One: Obtaining Your NIE Number

Before you can do anything of legal substance in Spain — including signing a purchase contract or opening a bank account — you will need a NIE number (Número de Identificación de Extranjero). This is your Spanish tax identification number, and it is the foundation upon which your entire purchase rests.

A NIE can be obtained in person at a Spanish consulate in your home country, or at a National Police station (Comisaría) in Spain. The process requires a completed application form (Modelo EX-15), your passport, and a small fee. Many buyers choose to appoint a local lawyer to obtain their NIE on their behalf via a power of attorney — a practical option if you are not yet resident in Spain and wish to move quickly.

Do not underestimate the importance of getting this done early. It is a simple step, but without it, nothing else can proceed.

Step Two: Appointing a Lawyer

Spanish property law is distinct from that of the UK, Ireland and Northern Europe in a number of important ways. While it is technically possible to proceed without independent legal representation, we would never recommend it. Your lawyer is not an optional extra — they are your most important investment in the entire transaction.

A good Spanish property lawyer will conduct thorough due diligence on your behalf: verifying that the property is correctly registered at the Registro de la Propiedad (Land Registry), checking for any outstanding debts or charges on the property, reviewing planning permissions and legal status, and ensuring that the title is clean and transferable. They will also review every contract before you sign and represent your interests at every stage, including at the notary.

Choose a lawyer who is independent of the developer or estate agent and who has demonstrable experience in Spanish property transactions. Many international buyers choose a bilingual lawyer — someone who can communicate fluently in both Spanish and English, ensuring that nothing is lost in translation at a critical moment.

Step Three: Opening a Spanish Bank Account

You will need a Spanish bank account to complete your purchase. All funds — your deposit, your stage payments if buying off-plan, and your final completion payment — must be transferred through a Spanish account. Your bank will also be the vehicle through which you pay your ongoing expenses: utility bills, community fees, property taxes, and so on.

Opening an account is straightforward for non-residents. Most major Spanish banks have English-speaking staff in their Costa del Sol branches, and the process typically requires only your passport, your NIE, and proof of address from your home country. Your lawyer can advise on the most convenient options for your particular circumstances.

Step Four: The Reservation Agreement and Deposit

Once you have found your property and agreed a price in principle, the first formal step is typically a Reservation Agreement (Contrato de Reserva). This is a short document that takes the property off the market in exchange for a reservation deposit — usually between €3,000 and €10,000, depending on the property and the seller.

The reservation deposit is deducted from the final purchase price, but it is important to understand the conditions under which it is refundable — or not. Your lawyer should review the reservation agreement before you sign and ensure that your interests are properly protected.

Step Five: The Private Purchase Contract

The Contrato de Compraventa (Private Purchase Contract) is the substantive legal agreement between buyer and seller. This is the document that commits both parties to the transaction on the agreed terms: price, payment schedule (in the case of off-plan purchases), completion date, and any conditions or special clauses.

At the point of signing the private purchase contract, the buyer typically pays a deposit of 10% of the purchase price (less any reservation fee already paid). Under Spanish law, this deposit operates on a penalty basis: if the buyer withdraws without legal cause, they lose the deposit; if the seller withdraws, they must return the deposit doubled. Your lawyer will explain the specific terms in detail.

Step Six: Due Diligence

Between the private purchase contract and completion, your lawyer will conduct a comprehensive programme of due diligence. This is where the value of good legal representation is most clearly felt.

Key checks include: confirming clear title at the Land Registry; verifying that there are no debts, mortgages or encumbrances registered against the property; confirming that all community fees and local property taxes (IBI) are up to date; checking that the property has valid planning permissions and, where applicable, a first occupation licence (Licencia de Primera Ocupación); and reviewing any community statutes if the property forms part of an urbanisation or residential complex.

For new-build or off-plan properties, your lawyer will additionally verify that the developer holds all necessary licences, that your stage payments are protected by a bank guarantee, and that the building specification is accurately reflected in the contract.

Step Seven: Arranging Finance

If you require a mortgage to complete your purchase, it is essential to begin the process early. Non-resident buyers can obtain Spanish mortgages, though the terms differ from those available to residents — most notably in the loan-to-value ratio, which is typically capped at 60–70% for non-residents compared to up to 80% for residents.

Spanish lenders will assess your income, your existing financial commitments, and the independent valuation of the property. Processing times can vary, and a mortgage offer is generally required before a completion date can be confirmed. We work closely with experienced independent mortgage brokers who specialise in non-resident finance and can guide you to the most competitive products available in the current market.

Step Eight: Completion at the Notary

Completion in Spain takes place in the presence of a Notario — a public official appointed by the Spanish state whose role is to verify the identity of the parties, confirm the terms of the transaction, and ensure that the deed of sale (Escritura de Compraventa) is executed correctly. The notary is impartial: they represent neither buyer nor seller, but the integrity of the legal process itself.

At completion, the buyer pays the balance of the purchase price (typically by bank transfer or certified bank cheque), the notary reads and certifies the escritura, and ownership formally transfers. You will leave the notary’s office with a copy of the signed deed — and the keys to your new home.

Step Nine: Post-Completion Obligations

Completion is not quite the final step. In the weeks that follow, your lawyer will register the escritura at the Land Registry in your name — a critical step that formally establishes your legal ownership. They will also handle the payment of the relevant purchase taxes: Transfer Tax (Impuesto de Transmisiones Patrimoniales) on resale properties, or VAT (IVA) plus Stamp Duty (AJD) on new-build properties.

Once registration is complete, you will need to set up your utility accounts, register with the local municipality if you intend to be a resident, and ensure that any ongoing taxes — particularly the annual IBI (local property tax) — are correctly set up in your name.

The Costs You Should Anticipate

The total acquisition costs for a property purchase in Spain typically amount to between 10% and 13% of the purchase price, depending on the region and the type of property. These costs include purchase taxes (Transfer Tax at 7% for resale properties in Andalucía, or IVA at 10% plus AJD at 1.2% for new builds), Notary fees, Land Registry fees, and legal fees. Your lawyer and agent will provide you with a detailed cost estimate at the outset so that there are no surprises.

A Final Word

The Spanish property purchase process, approached with the right team around you, is genuinely manageable — and ultimately, deeply rewarding. The complexities exist not to deter buyers but to protect them, and the legal framework, when properly navigated, provides real security.

What matters most is choosing your advisors wisely: a good agent who knows the market, a good lawyer who knows the law, and a good broker who knows the finance. Get those three right, and the rest follows.
