Nearly every problem foreign buyers run into in Spain traces back to the same three root causes: skipping proper legal due diligence, underbudgeting for the real cost, and assuming their home country’s process applies here. Below are the most common pitfalls — and how to sidestep them.
- Going without your own independent lawyer
If there’s one rule that matters above all else, it’s this: bring in your own legal counsel. Not the seller’s, not whoever the agency points you to — an independent abogado working solely for you. A competent lawyer will pull the land registry extract (nota simple), confirm there are no hidden debts or legal complications, check the property complies with planning regulations, and go over every contract before signature. The fee — usually around 1% of the price, is a small price against what it can save you.
- Overlooking debts tied to the property
In Spain, certain obligations follow the property rather than the owner. Unpaid IBI (property tax), overdue community fees, or a mortgage still on the books can all pass to you once you take ownership.
Your lawyer should pull together:
A nota simple from the Land Registry, showing any mortgages or charges
An IBI certificate from the town hall, confirming taxes are paid up
A certificate from the community administrator confirming no outstanding fees
Recent utility bills (electricity, water, gas)
- Not budgeting for the real total cost
The sale price is only the starting point. Taxes, notary fees, registration, and legal costs typically push the total 10–13% higher. A property priced at €500,000 will realistically run you €560,000–580,000 by the time everything is settled.
- Starting without an NIE
The NIE (foreigner ID number) is a prerequisite for almost every step — signing the deed, paying taxes, opening a bank account, setting up utilities. Without it, everything grinds to a halt.
Apply as early as possible. Within Spain, it typically takes 1–3 weeks through a police station; through a Spanish consulate abroad, 4–8 weeks. A lawyer or gestoría can handle the application
- Expecting mortgage terms similar to your home country
Spanish lenders treat foreign buyers differently. Non-residents can usually count on financing only 40% – 60% of the property’s value, meaning a 40% -60% cash deposit plus another 10–13% for taxes and fees — in total, 50 – 70 % of the price in cash.
Secure mortgage pre-approval before you start viewing properties. It sets your real budget and signals to sellers that you’re a serious buyer.
- Skipping the Contrato de Arras
This private purchase agreement locks in the deal with a 10% deposit and creates binding commitments on both sides. Walk away as the buyer, and you forfeit the deposit; if the seller backs out, they owe you double.
Some buyers skip this step to save time, which leaves them exposed to the seller taking a better offer elsewhere. Have your lawyer review and sign the arras agreement before you spend money on surveys, mortgage applications, or legal checks.
- Assuming short-term rentals are automatically permitted
Many buyers plan to list on Airbnb, only to learn that tourist-rental regulations vary by region and even by municipality. A property that’s rentable in one town or building may be restricted in another.
Before buying with rental income in mind, confirm that a tourist rental licence is actually available for that specific location — your lawyer should verify this with the local town hall and the regional tourism authority.
- Forgetting about ongoing tax obligations
The purchase itself is just the beginning. Even a holiday home used only by you, never rented out, comes with recurring costs:
IBI (annual property tax) — 0.4–1.1% of cadastral value
Non-resident imputed income tax, based on a notional rental value (1.1–2% of cadastral value, taxed at 19% for EU residents, 24% for non-EU)
Wealth tax, which may apply depending on the property’s value and region
If you do rent the property out, that income must also be declared and taxed separately. A Spanish tax advisor (asesor fiscal) can set up your annual filings and keep you compliant.
