Mortgage in Spain with foreign income: how the bank checks it
The law requires the bank to check any income equally deeply. With foreign income that is harder to pass: documents, translation, currency. What to prepare and how not to derail the timetable.
A Spanish bank checks foreign income under the same rules as local income: Ley 5/2019 reguladora de los contratos de crédito inmobiliario (the Real Estate Credit Contracts Act) obliges it to assess "en profundidad" (in depth) the borrower's job, current and future income, assets, savings, regular expenses and existing obligations (art. 11). The difference is in the evidence. Foreign tax returns, statements and income in another currency are harder for the bank to verify, so there are more documents and the timelines are longer.
What the bank must check by law
Evaluación de solvencia (the creditworthiness assessment) is the mandatory check of the borrower's ability to repay a loan before the contract is signed. The law lists what it includes and sets three limits that help the borrower.
First: the assessment cannot rest mainly on the value of the collateral or on the expectation that it will rise (art. 11.3). An expensive flat does not replace documented income. Second: the bank states in advance and clearly which data and which independently verifiable evidence it needs and by what deadline (art. 12.1). Third: if it refuses, it says so in writing and with reasons (art. 11.6).
If the loan runs past retirement age, the bank also assesses expected income after the end of working life (art. 11.1). With a long term and foreign income this is a separate set of documents on pension rights.
According to the Banco de España, the bank also queries CIRBE (the Bank of Spain's credit register) for debts at other banks and looks at defaulter registers such as RAI and ASNEF. Information about loans in the country where you earn your income is easiest for the bank to get from you, so it is better to disclose it yourself: the obligations are part of the check anyway.
Which documents to prepare for foreign income
The bank sets the exact package, but the logic comes from art. 11: each factor of the check needs its own evidence.
| What the bank checks | How foreign income is proved | What to watch |
|---|---|---|
| Employment | Employment contract or employer's letter | Contract term and probation period |
| Current income | Tax returns of the country of residence for several years | Whether amounts match the statements |
| Future income | Payment history, contracts, business accounts | Whether the bank counts one-off bonuses |
| Assets and savings | Account statements, brokerage reports | Origin of the funds for the deposit |
| Expenses and obligations | Loans, rent, maintenance payments in the income country | Better disclosed at once |
| Income after retirement | Pension rights, if the loan term runs past retirement | Required with a long term |
For income from your own business the evidence is different: the company's accounts and returns instead of an employer's letter. Each bank decides translations and document formats itself, so the list is clarified before collecting, not after.
How the currency of income changes the burden
A mortgage in euros with income in another currency leaves the currency risk with the borrower. If the loan itself is in a foreign currency, the law gives the right to convert it into the currency of the main income or of the country of residence, and if the contract does not limit the currency risk, the FEIN (the standardised European information sheet) shows an example of a 20% exchange-rate swing (art. 20 of Ley 5/2019). For a loan in euros there is no such rule, but it is useful to run the same stress test yourself.
Worked example, not a forecast. Income of 6,000 units of a foreign currency a month, which at the current rate is 6,000 €. Mortgage payment 1,800 €.
| Exchange rate against the euro | Income in euros | Payment as a share of income |
|---|---|---|
| As now | 6,000 € | 30% |
| Currency 10% weaker | 5,400 € | 33.3% |
| Currency 20% weaker | 4,800 € | 37.5% |
The payment in euros does not change; your income in euros does. The bank may apply its own safety margin to foreign-currency income, and its method should be asked about directly. How to move money for the deposit and what the bank checks on a transfer is covered in the article on international transfers.
How to fit the income check into the purchase timetable
Checking foreign income takes longer, so it is started before a flat is chosen.
- Ask the bank for a written list of documents and the deadline for submitting them: this is its duty under art. 12.1.
- Collect returns, statements and letters for the same period so that the amounts agree.
- Get a pre-approval; why it is needed is explained in the article on mortgage pre-approval.
- When signing the arras (reservation deposit contract), align the period to the escritura (the notarial deed) with the bank's real timeline and a condition for the case of refusal. The wording is written by the abogado (lawyer).
- Allow for the tasación (the bank's valuation): the bank will check the property too, and how this works is described in the article on bank valuation.
- Account for the mandatory periods: the FEIN and the FiAE (the standardised warnings sheet) are issued at least ten days before signing, and the notary advises the borrower free of charge and draws up the record no later than the day before signing (Banco de España, link above).
When a mortgage on foreign income does not suit
It is a poor option if income is irregular and hard to prove with documents covering several years: the bank must refuse when the check cannot be carried out (art. 12.3). It is risky if the income currency swings sharply against the euro and the payment has no cushion. It is awkward for a short project of buying, renovating and selling: interest and the bank's requirements for the property get in the way of the timetable, which is covered in the article on mortgages for non-residents. And it does not suit a purchase made through a company: that is a different loan with a different check.

Questions and answers
Do banks in Spain grant a mortgage if the whole salary comes from another country?
The law does not forbid it: the bank must check income under art. 11 of Ley 5/2019 regardless of the country. In practice there are more documents, and the decision and terms depend on the specific bank.
Which documents about foreign income does a Spanish bank ask for?
Usually tax returns of the country of residence, an employer's letter or business accounts, account statements and details of current loans. The exact list the bank must name in advance, together with the submission deadline.
Does the bank take the exchange rate into account if income is not in euros?
A mortgage payment in euros is fixed, while income in euros moves with the exchange rate. How exactly the bank discounts foreign-currency income is its own decision, and it is worth asking before applying.
Must the bank explain a mortgage refusal?
Yes. Under art. 11.6 of Ley 5/2019 a refusal is communicated in writing and with reasons, and if it is based on data from a credit-history database, the bank names the database and its result.
Can an expensive flat make up for a small income?
No. Under art. 11.3 the assessment cannot rest mainly on the value of the collateral or on the expectation that it will rise, except for loans for building and renovating housing.
