Every Spanish property purchase, and every Spanish mortgage, starts with paperwork. The good news: the list is shorter than most buyers fear, and almost all of it can be arranged from your home country. Here's what the NIE number is, how to get one, and exactly which documents lenders will ask you for.
What is an NIE number?
The NIE (Número de Identidad de Extranjero) is Spain's identification number for foreigners. It isn't a visa, a residency permit or a work authorisation. It's a tax identification number that lets you carry out official and financial transactions in Spain. You'll need it to buy property, open a Spanish bank account, sign a mortgage deed, pay purchase taxes and set up utilities.
Without an NIE, nothing in your purchase can complete. That's why we recommend applying for it as one of your first steps, ideally before you've chosen a property.
How to get an NIE
There are three standard routes, and none of them requires you to live in Spain:
1. In Spain, in person
You can apply at a national police station (comisaría) with a foreigners' office. You'll complete the application form, present your passport, explain the reason for the request (buying property is a standard one) and pay a small administrative fee. If you're already planning a viewing trip, this can be a practical time to do it.
2. Through a Spanish consulate abroad
Spanish consulates in your home country accept NIE applications. Processing routes and waiting times vary by consulate, so check your nearest one early. In some countries appointments book up well in advance.
3. By power of attorney
The most convenient route for many international buyers: grant power of attorney to a lawyer in Spain, who applies for the NIE on your behalf. The same power of attorney can often be drafted to cover other steps of your purchase too, such as signing at the notary, which helps if you'd rather not fly out for completion day.
Our team coordinates with trusted legal partners on exactly this kind of groundwork; it's part of the end-to-end support described on our How We Work Calculator page.
The document checklist for your mortgage application
Once your NIE is under way, the mortgage application itself rests on a consistent core of documents. Spanish lenders assessing a non-resident applicant will ask for:
| Document | What it shows the lender |
|---|---|
| Passport | Identity and nationality |
| NIE number | Your Spanish tax identification |
| Proof of income | Payslips for employees; accounts for the self-employed |
| Bank statements (6–12 months) | Income landing, spending patterns, deposit funds in place |
| Most recent tax return | Declared income, verified against payslips and statements |
| Credit report (home country) | How you've managed credit where you live |
Individual banks sometimes request supporting items on top, such as an employment contract, details of existing mortgages, or evidence of other assets. But if you have the six items above ready, you're well prepared for any lender among the 15+ we work with.
Getting your documents right first time
Consistency is everything
Underwriters cross-check your documents against each other: the salary on your payslips should appear in your bank statements, and your tax return should tell the same story. Discrepancies aren't fatal, but they generate questions and cost time. If something needs explaining, like a bonus, a job change or a large one-off transfer, flag it upfront.
Translations and format
Because our multilingual team works with buyers from 10+ countries, we know what each lender will accept in which language and format, and we'll tell you before you submit rather than after a rejection. Clear, complete PDFs of official documents are the baseline; some items may need official translation, which we'll help you arrange.
Show your deposit early
Your statements should show that your deposit and purchase costs, 30–40% of the price plus roughly 10–13% in taxes and fees, are available. Funds with a clear history are far easier to evidence than money that appears the week before you apply.
The payoff: a 14-day written pre-approval
Here's why the preparation matters. Once we receive your complete document set, we provide a written pre-approval within 14 days. That document changes your position as a buyer: agents take your offers seriously, sellers know your financing is real, and the formal application that follows, typically 4–8 weeks from application to offer, starts from a solid base rather than a scramble.
You can see how pre-approval fits into the wider process in our step-by-step Spanish mortgage timeline, and if you're still weighing up whether financing is right for you at all, start with our complete guide to non-resident mortgages in Spain.
