Buying property in Spain

Full guide →

Spain welcomes foreign buyers with no nationality restrictions. The buyer needs an NIE (Número de Identidad de Extranjero) before completion, and most buyers open a Spanish bank account to handle the deposit and ongoing charges. An independent lawyer (abogado) is strongly recommended — the notario only checks the deed, not the wider title.

  • Spain ended its Golden Visa property route in April 2025.

  • Non-resident mortgages are widely available, typically 60–70% LTV.

  • Non-resident sellers face a 3% withholding from the sale price (retención), claimable against capital gains tax.

Always check community-of-owners (comunidad) debts and outstanding IBI before completion — they transfer with the property.

General guidance only — confirm specifics with a qualified local lawyer or tax adviser. Reference
