If a foreigner wants to get a loan (e.g., a mortgage) in Spain, the bank usually requires several basic documents confirming identity, income and creditworthiness. The list may vary slightly depending on the bank, but most often the following are needed:
1. Identity documents

2. Income verification documents

recent pay slips (e.g., from the last 3–6 months)
tax returns (e.g., PIT for the last 1–2 years)
3. Financial documents

credit history from the country of origin (e.g., BIK report from Poland)
4. Additional documents (sometimes required)
preliminary purchase agreement for the property (if it’s a mortgage)
certificate of residence or stay
an open account with a Spanish bank
