Mistakes Foreign Buyers Make When Buying Property in Spain
After years of representing international buyers on the Costa del Sol, these are the mistakes we see most frequently — and the ones that cost the most money, time, and stress.
Should You Use the Selling Agent When Buying Property in Spain?
The selling agent is paid by the seller — typically 5% — and has a direct financial incentive to achieve the highest price. Many buyers assume the agent showing them properties is working for them. They are not. Buyers routinely overpay by 5-15%.
How to avoid it: Engage an independent buyer advisor who searches the entire market and negotiates exclusively in your interest. The fee is typically covered by a commission split with the selling agent.
Do You Need Your Own Lawyer When Buying Property in Spain?
We have seen cases where recommended lawyers failed to identify illegal construction, outstanding community debts, planning violations, or title discrepancies.
How to avoid it: Always appoint your own independent lawyer specialising in Costa del Sol conveyancing. Expect to pay 1-1.5% of the purchase price.
How Much Should You Budget Beyond the Purchase Price?
On a 1.5 million euro property, additional costs of 11-14% mean an extra 165,000-210,000 euros. Common forgotten costs: transfer tax, notary and registry fees, legal fees, mortgage costs, currency exchange costs (0.3-1.5%).
How to avoid it: Budget for 13-14% above purchase price. Use a specialist currency transfer service — savings on a 2 million euro transfer can exceed 20,000 euros.
How Do You Check if a Spanish Property Has Legal Building Permission?
Illegal construction is a genuine issue, particularly from the 1990s-2000s boom. Extensions, pools, or guest houses may lack planning permission, resulting in demolition orders or inability to sell.
How to avoid it: Insist your lawyer conducts a full planning and title audit: nota simple, certificado catastral, licencia de primera ocupación, PGOU compliance.
Should You Decide Quickly When Buying Property in Spain?
Buyers on viewing trips feel pressure to commit. The Costa del Sol has 3,000-4,000 luxury properties available. The urgency is usually manufactured.
How to avoid it: Take a refundable reservation deposit (6,000-10,000 euros) to buy 2-4 weeks of thinking time. Return home and review without emotional influence.
How Much Can Currency Fluctuations Cost You on a Spanish Property Purchase?
A 5% currency swing on a 2 million euro purchase represents 100,000 euros — more than all legal and notary fees combined.
How to avoid it: Lock in your exchange rate with a forward contract through specialists like Currencies Direct, Moneycorp, or OFX.
What Tax Obligations Do Non-Resident Property Owners Have in Spain?
Non-resident owners must file IRNR (deemed income tax), IBI (council tax), and wealth tax annually. Many buyers are unaware until they receive a notice.
How to avoid it: Appoint a Spanish fiscal representative before completion to file annual returns and advise on legitimate tax optimisation including the Beckham Law.
Should You Buy Spanish Property Through a Company Structure?
Properties held through companies in non-cooperative jurisdictions now face a punitive 3% annual tax on cadastral value. The compliance costs typically exceed any tax benefit.
How to avoid it: Buy in your personal name or through a properly structured Spanish SL with professional tax advice.
