Buying property in Spain from abroad.

NIE, bank account, power of attorney, taxes and letting: what you need to buy a rental flat in Spain without moving here.

By the Kaspar Capital team · Updated: October 2026

Most of our clients don't live in Asturias or León, and many don't live in Spain. Buying from abroad is perfectly feasible: this is how it works.

What you need

  • NIE (foreigner identification number): mandatory to buy, pay taxes and sign. It can be requested at a Spanish consulate in your country or in Spain.
  • Spanish bank account: recommended to pay taxes and bills and collect rent. Banks offer non-resident accounts.
  • Power of attorney (optional): granted before a notary in your country (with apostille) or at a Spanish consulate, so someone can sign on your behalf.

Step by step

  1. Brief: budget, target yield, city and rental strategy.
  2. Search and video viewings: we shortlist and show you each finalist live by video call.
  3. Checks: land registry extract (nota simple), charges, property tax, service charges and owners' association minutes.
  4. Offer and deposit contract (arras): typically around 10 % of the price, with a date to complete.
  5. Completion at the notary: you sign in person or through your power of attorney; the deed is then registered.
  6. Letting: refurbishment if needed, tenant selection and monthly management.

Taxes for non-residents (overview)

  • On purchase: transfer tax (ITP) on resale homes, 8 % in Asturias and in Castilla y León as a general rule, plus notary and registry fees.
  • On rental income: non-resident income tax (IRNR). As a general rule, 19 % on net income for EU/EEA residents (deducting expenses) and 24 % on gross income for residents elsewhere. Double-taxation treaties prevent paying twice.
  • Every year: local property tax (IBI) and, depending on your total assets in Spain, wealth tax.
Important: this is a general overview, not tax advice. Each case must be reviewed by a tax adviser before buying; we work with advisers who specialise in non-residents.

Where to invest

We focus on Asturias (Oviedo, Gijón, Avilés and the mining valleys) and León and Ponferrada: markets with higher yields than Madrid or Barcelona and lower entry prices. Spanish-speaking investors from Latin America can read our guide in Spanish.
