Buying a House in Altea as a Foreigner: 2026 Step-by-Step Guide

Buying a house in Altea as a foreigner follows the same legal process as for a Spanish national, with two extra steps at the start: getting an NIE number and opening a Spanish bank account. Everything after that (viewings, offer, deposit, notary) is identical. This guide walks through the full process in order, with who does what and how long each step takes.

Altea has welcomed British, Belgian, Dutch, and Scandinavian buyers for decades, and the process is well established locally: agencies used to working across several languages, notaries experienced with deeds for foreign buyers, and banks with dedicated desks for non-residents. That doesn't remove the paperwork, but it does reduce the surprises if you follow the steps in the right order.

Documents worth preparing before you start

Before booking a flight to view properties, gather these: a valid passport, proof of income for recent months (payslips, or tax returns if you're self-employed), and a clear sense of your total budget, not just the property price. If you're financing, add your recent tax returns and bank statements.

Having these ready from day one shortens the NIE step and, if you apply for a mortgage, gets the bank's assessment moving weeks earlier. The most common scheduling mistake is starting the property search before this paperwork is in place.

Step 1: get your NIE before you start viewing

Your NIE (Foreigner Identity Number) is the entry requirement. Any non-resident signing a purchase, opening a bank account, or applying for a Spanish mortgage needs one.

You can apply in two ways: at a Spanish police station with a prior appointment, or at the Spanish consulate in your home country before you travel. If you can't travel yet, a lawyer or gestor in Spain can apply on your behalf with a power of attorney.

Book your appointment well ahead. During peak season, immigration appointments fill up weeks in advance. We cover the full process in our guide to the NIE for buying property in Spain.

Your NIE doesn't expire and doesn't commit you to anything: you'll keep using the same number for years, whether that's filing your annual non-resident tax return, setting up utilities, or eventually selling the property. It's worth getting right from the start, even if your purchase plans take months to firm up.

Step 2: open a Spanish bank account

You need a Spanish account to pay the reservation deposit, the arras, the balance of the price, and the associated costs. Some banks let non-residents open an account remotely, others require an in-person visit.

Bring your NIE, passport, and proof of address from your home country. If you're applying for a mortgage, open the account with the same bank you'll borrow from. It speeds up the risk assessment.

This account stays with you well beyond the purchase: it's what you'll use to pay the annual IBI property tax, the community fees, and the utilities. Keep it active even if you don't live in Spain year round, and warn your home bank before making large transfers, some flag unusual international movements as potential fraud.

Step 3: view properties with an agent who knows the area

Altea has very distinct neighbourhoods: the Old Town, Altea Hills, Altea Pueblo, El Tossal, Albir, and the second-line urbanisations near the coast. Price and buyer profile vary a lot between them.

A good local agent saves you wasted viewings and flags what photos don't show: orientation, noise, real community fees. Browse villas in Altea Hills or houses in the Old Town depending on what you're after.

If your goal is a permanent home, a seasonal base, or a property you'll rent out as a holiday let when you're not using it, say so from the first viewing. It changes which type of property and which area suit you best: an apartment near the centre for holiday rentals is a different brief from a secluded villa for personal use. If holiday letting is part of the plan, see how we manage that through Azur Holidays.

Step 4: make an offer and sign the reservation

Once you find the property, the offer usually goes through the agency in writing. If the seller accepts, you sign a reservation contract and pay a holding deposit, typically between 3,000 EUR and 6,000 EUR, which is later deducted from the final price.

The reservation takes the property off the market while the deposit contract is drafted.

Step 5: the deposit contract (arras) binds both parties

The arras contract sets the price, the notary signing date, and what happens if either party pulls out. It's standard to pay between 10% and 15% of the price at this stage.

If the buyer withdraws without justified cause, that deposit is forfeited. If the seller withdraws, they must return double the amount. Have your own lawyer review this contract, not just the agency.

Step 6: check the land registry extract for charges

Before signing anything final, verify at the Property Registry that the home is free of mortgages, embargoes, or undisclosed easements. This document is called a nota simple.

It's also worth confirming that the local property tax (IBI) is paid up to date, there are no outstanding community fees, and the property has a valid habitation certificate or first occupation licence. We go into detail in what to check beyond the nota simple (in Spanish).

Step 7: apply for a mortgage if you're not buying in cash

As a non-resident, typical financing covers 60% to 70% of the appraised value, compared to around 80% often offered to residents. The exact percentage depends on the bank and your profile.

Start this in parallel with the land registry check, since banks require a valuation and paperwork that takes several weeks. Full detail in mortgages for non-residents in Spain.

Step 8: sign at the notary

On signing day, buyer and seller (or their representatives) attend the notary with the balance of the price, usually via a certified bank cheque or transfer. The notary reads the deed, answers questions, and both parties sign.

If you can't travel, your representative signs on your behalf under the power of attorney you granted earlier.

Buying in cash versus financing: how the timeline changes

If you're paying in cash, step 7 disappears and the timeline shortens: you can sign at the notary a few weeks after the deposit contract, as soon as the land registry check is cleared. If you're financing, the signing date depends on mortgage approval, so it's worth building some margin into the deposit contract rather than fixing a tight date.

Some sellers actually prefer cash buyers for that certainty on timing. It's not a requirement to buy, but it can give you some room to negotiate on price or on the date.

Step 9: pay the taxes and register the property

After signing, you have 30 working days to settle the relevant tax: transfer tax (ITP) for resale properties, or VAT plus stamp duty (AJD) for new builds, as of August 2026. The deed is then registered at the Property Registry.

Total buying costs (taxes, notary, registry, gestoría) typically run 10% to 12% of the price. Full breakdown with worked examples in taxes and costs of buying property in the Valencian Community.

Step 10: transfer utilities into your name

Water, electricity, and gas where applicable. Your gestoría can handle this once the deed is registered. Expect one to three weeks for the utility companies to update the account.

What happens in the first months after signing

The purchase doesn't end at the notary. In the following months you'll need to take out home insurance (some banks require it if there's a mortgage), confirm the community of owners has you registered as the new title holder for meeting notices, and sort out how you'll declare the property if you're a non-resident for tax purposes.

As a non-resident, Spain requires you to file an annual non-resident income tax return (form 210) even if you never rent the property out, calculated on a deemed income based on the cadastral value. If you decide to rent it part of the year, the filing changes, and it's worth having a gestoría handle it from the first year. This isn't something this guide can settle for you, so confirm the detail with a tax advisor once you have the deed.

If you plan to register as a resident because you'll spend more than 183 days a year in Spain, that's a separate step at the town hall, independent of the NIE and the purchase, with its own tax implications worth weighing with an advisor before deciding.

Who to lean on at each stage

You're not on your own for any of these steps, and it's worth not putting everything on one person's plate:

• Your estate agency knows the local market, filters properties that fit your brief, and coordinates viewings and the reservation.
• An independent lawyer reviews the deposit contract, the land registry extract, and the deed, representing only your interests as the buyer.
• A gestor or gestoría handles the NIE if you delegate it, settles taxes after signing, and organises the utility transfers.
• The bank, if you're financing, assesses your solvency and commissions the valuation.
• The notary, usually chosen by the buyer, certifies the deed and verifies both parties' identity and legal capacity.

Each plays a different role, and none replaces the others. The agency doesn't check legal charges for you, and the lawyer doesn't go property hunting. The more of these pieces you have lined up from the start, the fewer surprises show up midway through.

Mistakes that slow the process down

Foreign buyers tend to trip up in the same places: arriving without an NIE, skipping an off-season visit to the area, or trusting photos without walking the property first. We cover them all in the most common mistakes when buying on the Costa Blanca (in Spanish).

This is general guidance on the process, not legal or tax advice: confirm your specific situation with a lawyer or advisor before signing anything.
