NIE and the Property-Buying Process in Spain for Foreigners (Costa Blanca)

What the NIE is and why you cannot buy without it

The NIE, or Número de Identidad de Extranjero, is the personal number the Spanish National Police assigns to any foreigner with economic, professional or social ties to Spain. Buying property counts as one of those ties: without an NIE you cannot appear as the owner on the deed, settle the purchase taxes or register the home in your name at the Land Registry.

One point trips up a lot of buyers: the NIE is not a residence permit. It is purely a tax identification number for foreigners. A British, American or Norwegian buyer picking up an apartment in Jávea or Calpe as a holiday home needs the NIE, but it does not make them a resident or force them to declare worldwide income in Spain.

The number follows you through the whole transaction. The notary asks for it before authorising the deed, the bank needs it to open your account, the electricity and water companies use it to put utilities in your name, and the tax office requires it to process the transfer tax. That is why obtaining it is the very first task in any purchase.

How to apply for the NIE with the EX-15 form

You request the NIE using the EX-15 form, the official assignment application. In box 4.3 you tick where you are filing it: Immigration Office (Oficina de Extranjería), Police Station (Comisaría de Policía) or Consular Office (Oficina Consular). There are two main routes depending on where you are.

From your home country, you go to the Spanish consulate that covers your address. You hand in the completed EX-15, your valid passport plus a copy and, depending on the consulate, evidence of why you need it (the property purchase). The consular route usually takes two to four weeks and saves you a trip to Spain just for this paperwork.

Inside Spain, you book an appointment (cita previa) at a police station or immigration office. You bring the EX-15, your passport and a copy, and proof of payment of the Modelo 790 código 012 fee, which is around 9.84 euros and is paid at a bank before your appointment. In person the NIE is frequently issued the same day or within two to three days. Since 2026 many of these steps can be started online with a Cl@ve PIN or an FNMT digital certificate, though non-resident buyers still commonly use a lawyer or gestor acting under a power of attorney.

The property-buying process step by step

Buying on the Costa Blanca follows a fairly predictable order. Here are the steps:

1. Get your NIE. Everything else depends on it; you cannot sign or pay taxes without one.

2. Open a Spanish bank account. It is not a legal requirement, but it is close to essential — utilities, the IBI council tax and the banker’s drafts used to pay the seller all run far more smoothly from a local account.

3. Make an offer and pay the reservation. Once you agree a price, you sign a reservation agreement and pay a small holding deposit, usually 3,000 to 6,000 euros, taking the property off the market for a few days.

4. Due diligence. Your lawyer requests the nota simple from the Land Registry to confirm who owns the property, whether there are mortgages, embargoes or charges, and whether the legal description matches what you are buying. A nota simple is delivered online within hours.

5. Sign the arras contract. This private contract is the pivotal step. You typically pay 10% of the price as a deposit. Most deals use arras penitenciales: if you walk away you forfeit that 10%; if the seller pulls out, they must return double. Completion is normally set 30 to 90 days later.

6. Arrange your mortgage if you need one. With the arras signed, the bank values the property and approves the loan. Leave enough room inside that 30 to 90 day window.

7. Sign the deed before a notary. On the agreed date, buyer and seller sign the escritura pública de compraventa before a notary, the balance of the price is paid (usually by banker’s draft) and you receive the keys.

8. Pay taxes and register the property. You settle the transfer tax (or VAT on a new build) and the notary sends the deed to the Land Registry to record the home in your name. Registration takes roughly two to six weeks.

If you cannot be in Spain to sign, you can grant a power of attorney (poder notarial) to your lawyer so they can sign the deed and handle the formalities for you, which is very common among foreign buyers. From start to finish the process usually runs two to three months, and can be quicker for cash purchases.

Documents you will need

Have this paperwork ready from the outset so nothing stalls the deal. Most of it can be gathered while your NIE is being processed.

Mortgages for non-residents

Spanish banks do lend to non-resident foreign buyers, but they finance less than they would for a resident. The usual ceiling is 60% to 70% of the valuation or purchase price, whichever is lower. EU residents buying a second home can reach 70%; buyers from outside the EU tend to sit at 50-60%, especially where the bank cannot easily verify their credit history back home.

In practice that means putting down 30-40% of the price plus taxes and fees. On a 400,000-euro home, the deposit plus costs can push the initial cash outlay close to 200,000 euros. The bank will assess your income and generally wants your total debts to stay within 30-35% of your net monthly income.

For 2026, fixed rates for non-residents run roughly 3.8% to 4.5% for EU buyers and somewhat higher for those outside the EU. Variable mortgages are pegged to Euribor plus a margin of 1.5-2.5%. You will need your NIE and, in practice, a Spanish account before the bank completes the loan.

Taxes and costs on the Costa Blanca

On top of the price, plan for an extra 12% to 15% in taxes and fees. On a resale the main tax is ITP, the property transfer tax, set by the Valencian regional government.

There is good news for 2026: the Valencian Community has cut the general ITP rate from 10% to 9% for purchases from 1 June 2026 onward. Reduced rates exist too: 6% if the home will be your main residence, is worth no more than 180,000 euros and you are under 35, and as low as 4% for large families and people with disabilities who meet the income limits.

Buy a new build from a developer and you pay 10% VAT instead of ITP, plus stamp duty (AJD), which falls from 1.5% to 1.4% from 1 June 2026. Add notary fees, Land Registry registration and your lawyer’s fee. Hiring an independent lawyer is strongly advised: the notary certifies the signing but does not defend your interests or check the property for debts on your behalf.
