The headline difference: loan-to-value
The single biggest difference between a resident and non-resident mortgage in Spain is how much of the property's value the bank will actually finance. Fiscal residents can typically access financing up to around 80% of the appraised value. Non-residents are financed more conservatively — commonly in the 60–70% range for buyers from the EU/EEA, and often somewhat lower, in the 50–60% range, for non-EU and UK buyers post-Brexit. In practice this means non-resident buyers should plan to bring a substantially larger cash deposit than they might expect from home-country norms, plus the usual notary, registry, and transfer tax costs on top.
Get pre-approval before you make an offer, not after. Non-resident applications take longer to underwrite than resident ones, and Spanish purchase contracts move fast once you're under offer — a slow mortgage process is one of the most common reasons a buyer loses a property to a cash offer.
Extra documentation for US buyers
US applicants should expect additional paperwork tied to FATCA compliance — banks will typically request a completed Form W-9 and supporting IRS documentation as part of the file, on top of the standard income and asset verification every non-resident applicant provides. Some banks also apply a conservative adjustment to income or asset figures quoted in USD to account for currency movement between application and closing, so a pre-approval based on a specific exchange rate can shift slightly by the time you're ready to sign.
The UK position post-Brexit
UK nationals remain fully eligible to apply for a Spanish mortgage after Brexit, but are now treated as non-EEA applicants rather than under the more favorable EU/EEA terms — which generally means the same 50–60% loan-to-value range that applies to other non-EU buyers, rather than the somewhat higher ceiling still available to EU nationals. This is a structural change from the pre-Brexit position, not a temporary market condition, so UK buyers should plan around it rather than expect it to shift back.
What to actually compare between lenders
Because mortgage rates and product terms shift with the broader market, get current, written quotes from at least two or three lenders rather than budgeting around a number you saw in an article or forum — rates for non-residents have moved noticeably in recent years, and some banks have pulled specific products (like long fixed-rate terms on larger loans) from the non-resident market entirely. What's stable enough to plan around in advance is the structural picture: lower loan-to-value than residents get, extra documentation for US applicants specifically, and non-EEA treatment for UK buyers. Note that financing a purchase this way no longer grants residency on its own — see our guide on Golden Visa alternatives if residency was part of your original plan.
