Dutch income, Spanish mortgage. We went through the process ourselves. Here's exactly what Spanish banks ask for — and where applications stall.
A Dutch payslip, tax return or BV structure makes perfect sense in the Netherlands. A Spanish bank sees it for the first time. If they cannot read your financial picture clearly, they will not guess. They will put the file aside.
We went through this process ourselves. Below is what we submitted, what the bank’s logic actually is, and where we see Dutch buyers run into problems.
What is a Spanish mortgage for non-residents? A mortgage issued by a Spanish bank to a buyer who is not a tax resident in Spain. The bank assesses your income, assets and creditworthiness based on documentation from your home country. Loan-to-value is typically 60–70% of the lower of purchase price or appraisal value — meaning you bring a larger deposit than you would at home. See How much can you borrow in Spain as a non-resident for LTV detail.
Spanish banks do not have a standardised checklist that travels across borders. What they ask for is shaped by internal risk appetite, by which lenders are active in the non-resident market, and by what your file looks like when it arrives.
That said, there is a core set of documents every lender we encountered required. We submitted these ourselves during our 2025 purchase in Baix Empordà — this reflects our own file in detail, plus what we observed through the coordination process.
Identity and residency status
Income
Proof of own funds
Liabilities
If you hold rental income: it generally needs to appear in your Dutch tax documentation before a Spanish bank will take it into account. If it is not in the paperwork you submit, it is not in their calculation.
For employees, the assessment is relatively straightforward: the bank looks at gross income, converts it to a net monthly figure, and applies their debt service ratio.
For self-employed earners, the bank’s logic is different. They look at the trajectory of your income across the three submitted fiscal years — not just the most recent figure. Rising income across those three years reads positively. A flat or declining trend creates questions, even if the absolute number is acceptable.
This is not a rule that is written down anywhere we found. It is how the files are read in practice.
Two situations come up repeatedly in the non-resident mortgage process for Dutch buyers. Neither is insurmountable, but both need to be understood before a file is submitted.
The BV structure problem
In the Netherlands, operating through a BV (besloten vennootschap) is common. Many directors — DGA’s — draw a modest salary from the BV (the wettelijk minimum DGA-salaris or somewhat above) and leave profit in the company. It is tax-efficient at home.
Spanish banks do not look at what sits in the BV. They look at what you take home — the salary declared in your personal tax return. A DGA drawing €50,000 per year in personal income while their BV holds substantial profit will be assessed on the €50,000. The profit in the company does not count toward borrowing capacity unless it has been distributed and appears as personal income in a tax return.
This is one of the more frustrating mismatches between Dutch and Spanish financial logic, and it catches people off guard. The business is doing well; the mortgage application looks weak.
The source of funds problem
In our own application, we spent more time documenting where our money came from than documenting how much we earned. That surprised us — and it is one of the things we flag early when coordinating a file now.
Spanish banks are thorough on where your deposit comes from — not just that it exists. They want to see that the money is yours, that it has been in your account, and that you can explain how it arrived.
This creates a problem when the route is indirect. A loan from a family member. Money moved through an intermediary account. A transfer from a partner’s account. A BV dividend that was paid to a holding and then distributed further. Each link in the chain that the bank cannot follow through documentation becomes a question mark.
The underlying principle: borrowed money is not own funds. If the bank concludes that your deposit was funded by a loan — even informally, even from your own company — it typically does not count as own equity for the purposes of their LTV calculation.
None of this is unique to the Dutch market. But the mismatch between how Dutch entrepreneurs structure their income and what Spanish banks expect to see is significant enough that it is worth understanding early — before a purchase price is agreed.
The documentation list above is a starting point. The non-resident mortgage documents checklist has the full version with deadlines and format requirements.
