The waiting room of a notary's office just off Avenida Ricardo Soriano in central Marbella is one of the calmer corners of the town. On a Tuesday morning in May, the air conditioning hums against the heat outside, a stack of property files waits on the reception desk, and a couple in their fifties are turning the pages of a thick document a bank handed them ten days earlier. They are not buying anything today, and they are not signing anything either. This is the acta previa — the appointment where a notary confirms, clause by clause, that they understand the mortgage they are about to take on.
That appointment is a legal requirement, and it is a useful reminder that financing a home on the Costa del Sol has its own rhythm, its own paperwork and its own timeline — it is not a formality bolted onto the purchase at the last minute. For most non-resident buyers, the mortgage is the part of the transaction with the longest lead time and the most moving parts. Getting it right means understanding three things before you ever shortlist a property: how much a Spanish bank will lend someone who lives abroad, what that money costs in 2026, and how the signing itself now works. This guide walks through all three, grounded in the market as it stood in May 2026.
How much will a Spanish bank actually lend?
Spanish banks are open to lending to non-residents, but they do so on more conservative terms than they offer residents. The headline figure is the loan-to-value ratio — the share of the property a bank is willing to finance. For buyers who are tax-resident elsewhere in the European Union, a Spanish lender will typically advance 60 to 70 per cent of the value of a second home. For non-EU buyers — a category that, since Brexit, now includes British purchasers — the range is usually lower, around 50 to 60 per cent. Since the great majority of Domosmar's buyers come from the UK, Ireland, Scandinavia and further afield, that single distinction shapes the conversation from the very first call.
There is a second detail that quietly catches buyers out. The loan-to-value percentage is not applied to the price you have agreed — it is applied to the lower of the agreed price or the bank's own valuation, the tasación. In a market where Marbella asking prices have been climbing steadily, an independent valuation can land below the figure written on the reservation contract. When that happens, the shortfall does not reduce the price; it simply enlarges the deposit you have to find. A buyer counting on a 65 per cent mortgage can discover, late in the process, that they need closer to 40 per cent in cash.
In practice, then, a non-resident should plan for a deposit of 30 to 50 per cent of the purchase price, with transaction costs stacked on top of that. Loan terms tend to be shorter as well: where a Spanish resident might borrow over 30 years, non-residents are commonly capped at around 25 years, and most lenders want the mortgage fully repaid by the time the borrower reaches 70 to 75. The younger and more straightforward the financial profile, the more flexible those terms become — but the conservative starting point is the one to budget against.
The cost of borrowing in May 2026
The reference rate for most Spanish mortgages is the 12-month Euribor. After the sharp rises of 2023 and the gradual easing through 2025, the index has been drifting upward again across 2026: having started the year at roughly 2.2 per cent, the 12-month Euribor stood at 2.83 per cent on 18 May 2026. That movement reflects a European Central Bank that has stopped cutting — the ECB held its deposit rate at 2.00 per cent at both its March and April 2026 meetings, citing renewed upside risks to inflation.
For borrowers, the practical choice is between a variable rate and a fixed rate. A variable Spanish mortgage is priced as Euribor plus a margin, and for non-residents that margin typically runs 1.5 to 2.5 percentage points. On today's index, that translates into an all-in variable rate somewhere around 4.3 to 5.3 per cent. Fixed-rate offers to non-residents in 2026 have generally sat in the high-3 to low-5 per cent range, depending on nationality, loan-to-value and the strength of the application. With Euribor no longer falling, a fixed rate currently looks competitive against a variable one — the reverse of the advice that held sway during the cutting cycle.
It is worth being clear-eyed about one thing. Non-residents almost always pay a premium over what a resident with the same property and the same income would be offered. The bank is pricing in distance, currency exposure and the practical difficulty of recovering a debt across borders. That premium is the cost of buying with finance arranged from abroad, and it is best treated as a known, fixed quantity in your planning rather than a late and unwelcome surprise.
Which banks lend to non-residents — and what they want to see
Not every Spanish bank is equally interested in non-resident business. On the Costa del Sol, the most active names in 2026 are Banco Sabadell, Bankinter, CaixaBank and UCI, with a handful of private banks competing for higher-net-worth clients. Each has its own appetite, its own margins and its own view of particular nationalities and property types, which is why many buyers work through an independent mortgage broker rather than walking into a single branch. A broker who places non-resident loans regularly will know which lender is genuinely competitive in a given month — and which one will simply absorb weeks of paperwork before declining.
Whichever route you take, the documentation is substantial. A bank will want recent payslips or, for the self-employed, two to three years of accounts and tax returns; personal bank statements; a summary of existing debts and assets; and clear evidence of where the deposit money comes from. That last point — source of funds — is consistently the slowest part of the process and the one most worth preparing early, particularly if the deposit has moved between accounts or countries. Spanish lenders also apply an affordability test, generally wanting total debt payments, the new mortgage included, to stay within roughly 30 to 35 per cent of net monthly income.
From a complete application, expect four to six weeks to a formal offer, and sometimes longer when paperwork has to be chased across borders or officially translated. That timeline is one good reason to scope a mortgage before, not after, you fall for a particular apartment. Treating financing as the first step of a structured purchase rather than the last is a theme we return to often; our note on a clearer way to start buying on the Costa del Sol sets out the wider sequence.
The 2019 law that slowed the signing down
Anyone borrowing in Spain today does so under the mortgage law that took effect in June 2019 — the legislation that created the acta previa described at the start of this article. Its central change is that a borrower now visits the notary twice. Once the bank approves the loan it issues a binding offer, the FEIN, and the borrower must then wait a minimum of ten days before the mortgage deed can be signed. During that window comes the notary appointment, at no cost to the buyer, where the notary checks that the terms are genuinely understood — and is entitled to ask questions to confirm it.
The 2019 reform also redrew who pays for what. The borrower remains responsible for the property valuation, the tasación, which runs roughly €400 to €700. The lender, however, now covers the stamp duty on the mortgage deed, the gestoría management fee, the notary's fee for the mortgage and the land registry charge. That is a meaningful shift from the pre-2019 position, when those costs all fell on the buyer. It does not touch the taxes on the purchase itself — transfer tax on a resale or VAT on a new build — but it does make the mortgage itself cheaper to set up than many older guides still suggest.
The same law swept away the so-called floor clauses that once stopped variable rates from falling, capped early-repayment penalties, and stopped lenders from bundling unrequested insurance and products onto a loan. Repossession proceedings can now only begin once a borrower is twelve months in arrears, rather than three. The net effect is a process that is slower and more procedural than it was a decade ago, but markedly safer for the person borrowing the money. The practical lesson is simply to budget the time: those ten days between the binding offer and completion are not negotiable, and they sit on top of the weeks the application itself takes.
Putting numbers on a Nueva Andalucía purchase
Abstract percentages are easier to grasp against a real figure. Take Nueva Andalucía, Marbella's Golf Valley, where Idealista recorded an average price of 5,654 €/m² in February 2026 — a fresh high for the area, up 6.6 per cent on the year. A comfortable three-bedroom resale apartment of around 130 m² in that market sits near €750,000. Assume an EU-resident buyer securing a 65 per cent mortgage. The loan is €487,500; the deposit is €262,500 — and that is before a single euro of transaction cost.
On a resale property in Andalucía, the largest single cost is transfer tax — ITP at 7 per cent, or €52,500 on this purchase. Add the notary and land registry fees for the purchase deed, an independent lawyer at roughly one per cent of the price, and the mortgage valuation, and the buyer is looking at perhaps €6,000 to €9,000 more. Total cash needed before completion therefore lands somewhere around €320,000 on a €750,000 home. A new build would shift the tax line — 10 per cent VAT plus a smaller stamp duty rather than ITP — and change the arithmetic accordingly, which is why the new-build versus resale decision is partly a financing decision.
The monthly cost is the easier half of the picture. A €487,500 loan over 25 years at a fixed rate near 3.9 per cent works out at roughly €2,500 to €2,600 a month. For many international buyers that figure is comfortably manageable; it is the upfront deposit and costs, not the monthly payment, that form the genuine gate. These numbers are illustrative — every bank, profile and property produces its own result — and no article can replace tailored advice. Engaging a Spanish abogado and an independent mortgage broker early is not optional polish; it is the difference between a smooth completion and an expensive one.
The wider backdrop is encouraging for buyers who plan ahead. The Costa del Sol has consolidated its reputation as a safe-haven market — agencies operating in Marbella have forecast further price growth of 7 to 8 per cent in the town across 2026 — while borrowing costs, though no longer falling, sit well below their 2023 peak. A financed purchase is entirely realistic for a non-resident, provided the deposit, the timeline and the paperwork are understood from the outset rather than discovered along the way.
