Update — June 2026: Spain’s Supreme Court (judgment no. 620/2026, 21 May 2026, reaffirmed in June 2026) has struck down the national “Registro Único” short-term rental registry (the NRUA) created by Royal Decree 1312/2024, as an unconstitutional intrusion on the autonomous regions’ competences. The national NRUA registration number and its annual declaration no longer apply; your regional tourist licence (VFT/ETV/VV) and the Ventanilla Única still do. Full analysis: Spain’s Supreme Court strikes down the national rental registry.
Quick answer: Before buying a property in Spain to let to tourists, verify five things in writing: the regional tourist licence, the national NRUA registration, the community of owners’ position on tourist use, the property’s urban-compatibility and occupation certificates, and a written licence-transfer clause in the arras contract. Completing this checklist before you sign is what separates a working holiday-let investment from a legal dead end.
The 2026 pre-purchase due-diligence checklist
Work through these five steps in order. Each one can stop a purchase from becoming a problem.
- Confirm the regional tourist licence (VFT) is valid and in the seller’s name. In Andalusia, check the property is registered as a Vivienda con Fines Turísticos in the Registro de Turismo de Andalucía, and that the registration is current — not lapsed or under an open infraction file.
- Check the national NRUA registration. Since 1 July 2025, every listed short-term let needs a Número de Registro Único de Arrendamiento obtained through the Ventanilla Única Digital. Confirm the number exists and matches the property — a regional licence alone is no longer enough.
- Get a written certificate from the administrador de fincas. Before signing the arras, obtain written confirmation that the community of owners has not voted to prohibit, restrict or condition tourist use. Under the Horizontal Property Law a 3/5 majority can ban it — and a verbal “it’s fine” is not protection.
- Verify the urban and building paperwork. Check the municipal urban-compatibility report (that the zone permits tourist use), the first-occupation licence and, where applicable, the habitability certificate. These underpin both the regional and national registrations.
- Put the licence transfer in the arras contract. If the seller promises a “transferable licence”, require the licence number, issue and renewal dates, any open infractions, and a written commitment to file the change of titleholder (cambio de titularidad) — with a penalty clause if they fail.
Why this matters in 2026
Enforcement is intensifying. Platforms now verify registration numbers and delist non-compliant properties, owners must file an annual informative return on their bookings, and fines for letting without valid registration have reached €600,000 in the most serious cases across Spain. The buyers who lose money are almost always the ones who discovered a problem after completion, when the deposit was already gone.
