Lawyers and Financing: The Two Decisions That Shape Your Purchase in Spain
Most of what goes wrong in a Spanish property purchase goes wrong in one of two places. Either something about the property itself was never properly checked, or the money was arranged too late and the timetable collapsed around it.
Both are avoidable. Neither is complicated once you understand how the Spanish system actually works, which differs in one important respect from the system most international buyers know at home. This guide covers the legal side, the financial side, and the point at which the two meet.
Why the Notary Is Not Your Lawyer
This is the single most important thing to understand, and it catches out buyers from the UK, the United States and much of northern Europe every year.
Every property sale in Spain completes before a notary, a public official. The notary confirms the identity of the parties, checks that the deed is legally correct, verifies that the title is registered to the seller, and formalises the transfer. That is a valuable function, and it is why Spanish transactions are secure at the point of signature.
What the notary does not do is act for you. They are neutral between buyer and seller by design. They will not tell you the terrace was built without permission, that the community has voted a special levy for next year, that the pool house never appeared on the plans, or that the price you have agreed sits well above what comparable homes have achieved. None of that is their role, and none of it gets checked unless someone is instructed to check it.
There is also no legal requirement in Spain to use a lawyer at all. You can buy a two-million-euro villa in Marbella without one. It is simply a poor idea, and it is why every serious agency on this coast tells buyers to appoint one before anything is signed.
What an Independent Lawyer Actually Does
The word that matters is independent. Not the seller's lawyer, not the developer's lawyer, and not a name handed to you without your own check on it. Your lawyer acts for you alone, and you should feel comfortable asking who else in the transaction they have a relationship with.
The core of the work is due diligence, and on the Costa del Sol it covers a defined list. They obtain the nota simple, the Land Registry extract, establishing who owns the property and whether it carries a mortgage, embargo or other charge. They confirm that community fees, IBI and utilities are paid up to date. They verify that the property as built matches the property as registered — which is where undeclared extensions, enclosed terraces, converted basements and unregistered pools surface. They check the urban classification of the land and that the licence of first occupation exists. They read the community statutes and recent minutes, which is where a planned special levy or a restriction on letting appears.
That middle point matters more in Spain than elsewhere, because certain debts attach to the property rather than to the person who ran them up. Unpaid community fees and outstanding IBI can follow the home to its new owner. A buyer without representation can complete and inherit somebody else's arrears, entirely legally.
Your lawyer also drafts or reviews the reservation document and the private purchase contract, and this is where the terms that protect you are set: what the deposit does, what happens if either side withdraws, what condition the property is handed over in, what is included, and what follows if the searches turn up a problem. Those clauses are far easier to negotiate before money moves than afterwards.
One point specific to this market: where the seller is not tax resident in Spain, the buyer is required to withhold three per cent of the purchase price and pay it to the tax authorities on the seller's account. Your lawyer handles it. Getting it wrong leaves the buyer liable, which is not a thing to discover after completion.
Costs, Timing and Signing From Abroad
Legal fees on the Costa del Sol generally run at around one to one and a half per cent of the purchase price, with a minimum fee on lower-value homes. It is a small share of the total cost of buying, and it is the part of the budget that does the most work.
Engage your lawyer before you reserve, not after. Once a reservation document is signed and a deposit has moved, the terms are largely set, and a lawyer brought in at that point is reviewing decisions rather than shaping them. The better sequence is to have representation lined up while you are still viewing, so that when the right property appears there is no pause.
Two practical items run alongside. You will need an NIE, the Spanish foreigner's tax identification number, required to complete any transaction. And most international buyers grant their lawyer a power of attorney, allowing them to sign on your behalf and removing the need to be in Spain on a date the notary sets. For a buyer with a business to run in another country, that is often the difference between a calm completion and a scramble.
How Buyers Here Actually Fund a Purchase
A Spanish mortgage is one route among several, and at Marbella price points it is frequently not the one chosen. It is worth understanding the full set before assuming which applies to you.
Cash. A significant share of prime Costa del Sol purchases complete without borrowing. It is the simplest route, it strengthens an offer materially, and it removes the longest item from the critical path. The trade-off is opportunity cost on capital that could be working elsewhere.
A Spanish mortgage. Covered in detail below. The practical appeal for an international buyer is not only the borrowing itself — a euro-denominated loan against a euro-denominated asset means the debt and the property move together, which removes a currency mismatch that borrowing at home does not.
Borrowing at home. UK and US lenders will generally not lend against Spanish property, so the usual route is releasing equity from a property in your own country and bringing the proceeds across as cash. It is often quicker and can be cheaper, but it leaves you with a sterling or dollar debt secured on a home-country asset, funding a euro asset.
Lending against a portfolio. For buyers with investments held at a private bank, borrowing against the portfolio rather than liquidating it is common at this level. It avoids realising capital gains, it is usually fast, and pricing can be competitive — though the facility is typically repayable on demand and subject to the value of what secures it.
Developer staged payments. On a new development, the payment schedule is itself a form of financing: a reservation, a substantial payment at private contract, interim payments across construction, and the balance at completion, spread over eighteen to thirty months. Many buyers arrange a mortgage only for the final payment, if at all.
Most purchases combine two of these. The decision worth making early is which, because it sets your timetable.
What You Can Borrow in Spain as a Non-Resident
Spanish banks lend to non-residents readily, and the Costa del Sol is one of the markets they know best. Terms are tighter than for residents, and the gap surprises people.
A Spanish tax resident can generally borrow up to eighty per cent of a property's value. A non-resident from within the EU typically sits between sixty and seventy per cent, with sixty-five the most common offer. Non-EU buyers, including those from the UK and the United States, more often fall in the fifty to sixty-five band, though a strong profile moves that. Terms run to around twenty-five years, with most lenders requiring the loan to finish before the borrower's seventy-fifth birthday.
One detail here matters more than any other. The loan is calculated against the lower of the purchase price and the bank's own valuation, carried out by an independent appraiser the bank appoints. Agree a price of one million euros, have the appraisal come in at nine hundred and twenty thousand, and your sixty-five per cent is sixty-five per cent of the lower figure — you fund the difference in cash. On prime Costa del Sol resale stock, valuations usually land close to the agreed price. On unusual properties — rural, heavily modernised, non-standard construction — they can come in meaningfully lower.
And no bank will finance your purchase costs. Those need to be available separately, as set out in our guide to property taxes and costs when buying in Spain.
Fixed, Variable or Mixed
Spanish mortgages come in three shapes, and all three are actively offered to non-residents.
A fixed rate holds for the full term, typically twenty to thirty years, with non-resident pricing generally running in the three to four and a half per cent range depending on profile, loan size and lender. A variable rate is priced as Euribor plus a margin and reprices every six or twelve months, moving with the market in both directions. A mixed product fixes for an initial period and then converts to variable, which several Spanish banks promoted heavily at the start of 2026 as a middle path.
Compare total cost rather than the headline rate. Spanish lenders commonly improve pricing in exchange for life insurance, home insurance, a salary or pension deposit, or a card with the bank, and those bundled products carry a real cost the headline number does not show. Ask for the APR, which includes them. Several banks now also offer a small discount on properties with an A or B energy rating, which is increasingly relevant on new-build stock along this coast.
The Currency Question
This is the part that gets the least attention and, on a large purchase, frequently moves the most money.
If your funds are held in sterling, dollars, Swiss francs or Norwegian krone and the property is priced in euros, the exchange rate is a live position from the moment you agree a price. Several months typically pass between reservation and completion. A four per cent move against you over that period on a three-million-euro purchase is a hundred and twenty thousand euros — considerably more than the entire difference between a good mortgage rate and a poor one, and more than most buyers spend on legal fees, notary and registry combined.
Two things help. First, the spread you transact at is negotiable, and a specialist currency broker will generally price more keenly than a high-street bank's standard rate, particularly at size. Second, a forward contract allows you to fix a rate now for a payment due later, usually against a deposit, which converts an open position into a known number. It is not speculation — it is the opposite. You are choosing certainty over a bet.
Give this the same attention as the mortgage decision, and settle it at the point you agree a price rather than the week before completion.
The Process, and How Long It Takes
If you are borrowing in Spain, expect six to ten weeks from submitting a complete document pack to signing at the notary. The bottleneck is almost never the credit decision. It is documentation, and specifically evidence of where the money came from.
Banks will want identification and your NIE, two to three years of tax returns, recent payslips or company accounts if you are self-employed, six to twelve months of bank statements, a summary of existing debts, and a clear, evidenced account of the source of your deposit funds. Documents from outside Spain usually need sworn translation. Buyers who assemble this in advance complete comfortably. Buyers who start collecting after an offer is accepted are the ones asking the seller for an extension.
Get a decision in principle before you view seriously. It tells you your real budget rather than your assumed one, and it strengthens your offer in a market where sellers weigh certainty alongside price.
If you are buying off-plan, the mortgage is normally arranged close to completion rather than at reservation, since the valuation is done against the finished home. Plan for that rather than discovering it late.
Where the Two Sides Meet
They are not separate tracks, and the completion date is where they converge.
Spain's 2019 mortgage law gives borrowers real protection. The bank must provide binding pre-contractual documentation, including the standardised European information sheet, at least ten days before signing, and the borrower attends a free advisory session with the notary before the mortgage deed is executed, where the terms are explained and questions answered. Your lawyer should review the offer inside that window — early repayment terms, bundled products, the margin, any floor, and how the arrangement fee is charged.
One useful point of law: since 2018 the lender, not the borrower, pays the stamp duty on the mortgage deed. That removed a significant cost, and older guidance still gets it wrong.
The practical instruction is simple. Start both processes at the same time, and make sure your lawyer, your bank and your currency provider are talking to each other rather than each to you separately. Most completion delays on this coast come from the strands running at different speeds, not from any one of them failing.
Conclusion
Buying in Spain is a secure and well-structured process, considerably more so than its reputation among people who have never done it. But the security comes from the framework rather than automatically. The notary guarantees the form of the transaction. Your lawyer is the only party checking its substance. And the financing decision is wider than which bank to approach.
Appoint an independent lawyer before you reserve. Decide how you are funding the purchase before you view in earnest, currency included. Run the two in parallel and keep them in contact. Do those three things and the rest of a Costa del Sol purchase is the enjoyable part.
We are happy to introduce buyers to independent lawyers, mortgage brokers and currency specialists who work with international clients on this coast every week, and to sequence the timetable so that no one strand holds up another.
