What Are the Hidden Costs of Buying Property in Spain?

Taxes, notary fees and registration are the costs every buyer plans for. The ones below are the ones that quietly add up around them — individually small, but easy to underestimate as a group.

Before you sign

• Hire an architect: if you’re buying a house rather than an apartment, it’s worth bringing in an independent architect to check for structural defects or damage that isn’t visible at a glance. These are known as vicios ocultos (hidden defects), and catching them before completion can save a costly repair later
• Certified translations: contracts, ID documents and financial paperwork issued abroad often need an official translation into Spanish
• Power of attorney: if you can’t attend the signing in person, a Spanish notary needs to draw up a power of attorney, which carries its own notary and translation cost
• Currency exchange margins: transferring a large sum into euros through your everyday bank can quietly cost far more than using a dedicated currency broker
• Derramas (special community levies): in apartment buildings, owners can vote to approve a derrama — an extra charge, often paid monthly, to cover a major repair or improvement to the building. It’s worth checking with the community administrator whether any are already approved or under discussion before you buy

At completion

• Mortgage arrangement and valuation fees: separate from the interest rate, and easy to overlook when comparing offers
• Outstanding community fees or IBI: if the seller hasn’t settled these, Spanish law can make the debt follow the property, so a clear certificate from the community administrator is worth requesting
• Utility reconnection or transfer fees: water, electricity and gas contracts usually need to be switched into your name, sometimes with a small administrative charge

After you own it

• Non-resident income tax (IRNR): an annual tax on a notional rental value, owed even if the property sits empty
• Home insurance: often required by the mortgage lender, and worth having regardless
• Ongoing gestoría fees: many non-resident owners keep a local gestor on retainer to file annual tax returns
