Financial documents
These prove you have the funds for the deposit and can manage the mortgage payments:
- •Bank statements (6 months) — from all accounts you hold, showing regular income and savings
- •Proof of deposit funds — the bank wants to trace where your 30-40% deposit comes from (savings, investment sale, gift from family)
- •Credit report from your home country — UK: Experian/Equifax/TransUnion. US: any of the three bureaus. Other: equivalent national credit bureau
- •Existing debt summary — mortgages, car loans, credit cards in your home country. The bank calculates total debt-to-income ratio
The source of funds questionSpanish anti-money-laundering regulations require banks to verify the origin of your deposit. Be prepared to document the trail: savings accumulated over time (bank statements), property sale (completion statement), inheritance (probate documents), or gift (signed declaration). Unexplained large deposits will delay your application.
Property documents
These relate to the specific property you want to buy:
- •Arras contract or reservation agreement — if you have already agreed on a property
- •Nota simple — current registry extract showing ownership, charges and description (your lawyer typically obtains this)
- •Energy performance certificate (CEE) — legally required for all property sales in Spain
- •Community of owners certificate — confirming no outstanding debts if the property is in a complex
Translations and apostilles
All non-Spanish documents must be translated by a sworn translator (traductor jurado) — a translator officially certified by the Spanish Ministry of Foreign Affairs. Regular translations are not accepted.
Some documents may also need an apostille (Hague Convention apostille) to certify their authenticity. This applies mainly to official government documents (tax returns, certificates). Your lawyer will advise which documents need apostilling.
