Documents needed to apply for a mortgage in Spain
Banks ask for the same documents over and over. It's not that they lose them — every department operates in its own silo and none of them talk to each other. Get everything ready in digital format before you start. It saves weeks.
The core documents every bank asks for
These appear in every reported case, without exception:
- ID document (DNI/NIE) for all applicants
- Last 3 payslips (some banks ask for 4)
- Work history report (Vida Laboral) — download the PDF from the Social Security website (sede.seg-social.gob.es), it's free
- Last income tax return (Declaración de la Renta / IRPF) from the previous tax year
- Employment contract — or official appointment letter for civil servants
- Bank statements for the last 6 months from your main account (the one where your salary arrives)
- Preliminary purchase contract (contrato de arras) or reservation document, if you have already signed one
Some banks also ask for statements from other accounts you hold, particularly if you need to demonstrate savings. They want to see where the money comes from. If it doesn't add up, they ask.
Documents about the property
Once you have a specific property in mind:
- Land Registry extract (Nota Simple) — costs around 9 euros and can be ordered online at registradores.org. Read it carefully: it may show charges, easements, or discrepancies with the cadastral records.
- Valuation report (Tasación) — not needed for the initial study, but required before the bank issues a binding offer (FEIN). You can commission this yourself from companies like Tinsa, which all banks accept. Cost: 270-500 euros depending on the property.
- Cadastral reference of the property
Additional documents depending on your situation
If you rent: many banks also ask for your rental contract and recent rental receipts.
If you have other loans: you'll need to document them. Bank statements showing the monthly charges usually suffice.
If you have additional income (rental income, pensions, second jobs): you need to prove these too.
If applying jointly: all of the above is required from both applicants without exception. Some banks additionally require both applicants to be existing customers or to open a joint account before they will process the study. It's their way of capturing two clients instead of one.
If you are self-employed (autónomo): the requirements are significantly heavier. Banks ask for: recent tax returns, recent invoices, quarterly tax filings (Modelos 130 and 303 for IRPF and VAT), work history, certificates of being up to date with Social Security and the tax authority, and the registration form (Modelo 036). Banks work from closed data — they look at your last filed tax return, not projections. This can be a serious problem if you recently restructured your activity through a limited company (SL), since income held in the company won't count toward your personal IRPF.
If you have foreign income or employment history abroad: expect more friction. Most Spanish banks don't have processes for handling foreign payslips or tax returns. It's not that they won't — they can't.
How banks assess your income
Banks look at your gross annual income, not your net take-home pay. For the monthly calculation they use the net figure from your recent payslips. If you have bonus months or extra salary payments (14 or 16 annual payments instead of 12), some banks default to annualizing over 12 — worth pushing back on if they get it wrong.
Variable pay and bonuses are typically only partially counted or ignored entirely. Your 10,000-euro bonus doesn't exist to the bank.
When to submit real documents
For an initial ballpark (approximate rate, rough loan amount, whether you qualify as high earner) you don't need to submit anything: a verbal overview over the phone or in branch is enough. Real documentation comes later, when you have 2-3 serious candidate banks and want a binding offer (FEIN).
Approvals expire. If a bank pre-approves you and months pass without completing the deal, they will ask you to refresh your payslips, work history, and other documents before moving forward. The clock always runs in the bank's favor.
Practical tip
Create a folder on your computer with all documents as PDFs, clearly named. You will send the same package 4-5 times to different banks. Having everything ready from the start prevents delays caused by expired or missing documents.
