The practical lesson is to complete the title, planning, community-debt, tax, and off-plan checks before the deposit becomes binding, or to make the agreement expressly conditional on satisfactory results. This guide follows those checks in transaction order.

Everything here was verified against Spanish primary sources on August 14, 2026.

1. What happens to a reservation deposit if the purchase falls through?

Spanish purchases commonly involve two different deposit stages, and buyers sometimes assume the earlier payment has the protections of the later contract when it does not.

A reservation contract (contrato de reserva) is a small holding payment governed by nothing except its own text. What happens to the money if either side withdraws is whatever the document says, and a vague one leaves your holding deposit genuinely disputable.

Arras under Article 1454 are the statutory tier, with the double-or-forfeit rule.

Read the exact document and make it state what happens to the payment in each withdrawal scenario. A reservation agreement does not automatically receive the statutory treatment associated with arras.

2. Should you sign arras before due diligence is complete?

The risk comes from the order in which the deposit and due diligence occur.

Once qualifying arras have been signed, the buyer has normally fixed the cost of withdrawing, often 10% of the price in market practice, before knowing what later checks may reveal. If the registry then shows an embargo or the community certificate identifies unpaid fees, recovering the deposit may depend on the wording of the agreement and the nature of the defect.

Obtain the registry and community documents first, or make the arras expressly conditional on satisfactory due diligence and clean title. Resist pressure to sign merely to hold the property before those basic records can be reviewed.

3. Do the Property Registry and Catastro show the same information?

Spain keeps two parallel records, and they answer different questions.

The Registro de la Propiedad answers who owns it and what is owed against it. Its nota simple shows current ownership, mortgages, embargoes, and easements, and it’s the non-negotiable first document of any purchase.

The Catastro answers what it physically is and what the state thinks it is worth: boundaries, built area, and the tax-relevant values.

The systems are coordinated but not identical, and they can disagree about built area or ownership shares. A Catastro record does not reveal every mortgage or embargo, while the Property Registry does not by itself establish the physical reality. Obtain both records and reconcile discrepancies before signing arras.

The registrars describe the nota simple as “purely informative.” A certificación provides formal proof of the registry position and may be appropriate when an entry requires authoritative confirmation.

4. Can the buyer inherit unpaid community fees?

For an apartment or other unit in a community, Article 9.1.e of the Ley de Propiedad Horizontal makes the property itself answer for unpaid community charges from the elapsed part of the current year plus the three preceding years.

The same article requires the seller to declare their status and provide a certificate of community debts at the deed. Do not complete without a current certificate and a clear arrangement for any balance shown.

The seller requests the certificate from the community administrator. Allow time for it to be issued and investigate any delay or qualification rather than assuming the account is clear.

Inland and countryside Andalusia has many attractive listings classified as AFO (asimilado a fuera de ordenación). These are buildings constructed without, or in breach of, planning permission but old enough that the legal deadline for demolition has generally passed.

The Junta de Andalucía’s guidance is explicit: “El reconocimiento de la situación de AFO no legaliza la edificación.” Recognition does not legalize the building.

An AFO property can be registered, connected to water and power, mortgaged, lived in, and sold, and still be permanently irregular, with no first-occupation license and no path to full conformity. The nota simple will not tell you this; registration is not planning legality.

Ask the town hall and a qualified local técnico to confirm the building’s planning status in writing before any deposit is paid.

6. What proves that a new build can legally be occupied?

A finished-looking new build is not legally finished until its first-occupation documentation exists: historically the licencia de primera ocupación, now in Andalusia largely a declaración responsable filed on completion under the region’s current planning law.

Without the required documentation, the unit’s legal fitness for occupation and ability to obtain utility contracts may be uncertain. The building may look complete while its administrative close-out remains unfinished.

Make the relevant license or filed declaration for the specific unit a condition of completion. Your lawyer should identify the document required for the municipality and project and confirm that it has been validly filed.

7. How should off-plan payments be protected?

Spain requires specific protection for advance payments, but the payment must be made through the required structure.

Under the Ley de Ordenación de la Edificación’s first additional provision, rewritten by Ley 20/2015, a developer taking advance payments must guarantee their return with interest, through a bank guarantee or an individually-issued insurance policy naming you and your unit. The payments must sit in a segregated special account usable only for construction.

Do not send stage payments to an ordinary operating account merely because it is the developer’s usual practice. Have counsel confirm that the account and guarantee satisfy the statutory requirements.

Before each stage payment, obtain the guarantee or policy reference in your name and written confirmation that the receiving account is the segregated special account. If either cannot be produced, pause the payment and investigate.

8. Which Spanish property-tax rules can change your budget?

Three tax rules can surprise foreign buyers after the price is agreed.

First, the reference value. Since 2022, the amount used to calculate property transfer tax is effectively the higher of your purchase price and the Catastro’s official reference value for the property. A genuinely good deal does not buy a smaller tax bill, so look up the reference value before you budget.

Andalusia’s headline property transfer tax is a flat 7% on resales, with reduced rates for some primary residences. New builds pay VAT plus stamp duty instead. The complete purchase-cost calculation is covered in Spain buying costs.

Second, the 3% withholding. Buying from a non-resident seller, you, the buyer, must withhold 3% of the price and file it on Modelo 211 within one month, on pain of liability for the seller’s tax. Many buyers never learn this duty is theirs.

Third, municipal plusvalía. This is ordinarily treated as the seller’s tax, with additional collection considerations where the seller is non-resident. Have your lawyer confirm the statutory position and state in the contract who pays it and how any amount is retained at closing.

9. Which common assumptions are no longer safe in 2026?

Three beliefs still circulating in 2026 deserve a direct correction.

New property purchases no longer qualify for Spain’s golden visa. Spain’s investor-registration portal states that Organic Law 1/2025 left the investor-residence articles of the 2013 law “without content.” Existing holders may be able to renew, but a 2026 purchase does not create a new route under that program.

“You can Airbnb it” is a registration status, not a feature. In Andalusia, tourist rental requires registration in the tourism registry, the registration code must appear in all advertising, and community bylaws or municipal restrictions can block it for a specific unit regardless of what the platform will list. Verify the unit’s own status, not the concept.

The foreigner identification number, known as the NIE, and source-of-funds checks can affect the timetable. Apply for the number early. Spain’s anti-money-laundering law also requires several parties to verify identity and the origin of funds, so prepare a clear documentary trail before the closing process begins.

What do these nine risks have in common?

Spain’s buyer protections depend heavily on documents that must be obtained and checked at the right stage. These include the nota simple, any certificación, the community certificate, planning-status confirmation, first-occupation paperwork, the off-plan guarantee, the reference-value lookup, the Modelo 211 receipt where applicable, and the tourist-rental registration.

Collecting them before the deposit gives the buyer room to resolve a problem or walk away on agreed terms. Collecting them later can leave the buyer negotiating after substantial money is already at risk.

Where the coasts do differ (older Costa del Sol resale stock carrying more legacy extension-and-debt history, tightly-permitted Balearic new builds, and the Atlantic-coast markets), the checks stay identical; only the odds change.
