Luxury travel media signal
"Sardinia consistently ranked in global top island destinations — Condé Nast Traveler, Travel + Leisure, Forbes annual rankings"
Unlike emerging markets, North Sardinia benefits from four decades of established luxury brand value. Costa Smeralda was developed by the Aga Khan in the 1960s. This brand durability provides capital protection that emerging markets cannot match.
| Signal | Implication | Severity |
|---|---|---|
| Extreme seasonality (3-month peak) | Revenue concentrated Jun–Aug — off-season vacancy is near-total | Medium |
| CIN + IUN dual compliance (Sardinia) | Additional registration layer vs mainland Italy | Medium |
| Tax tightening — 26% from 2nd property | Multi-property investors face higher costs from 2025 | Medium |
| CIN compliance drove ~30% listing reduction | Reduced competition for compliant operators | Positive |
| Coastal supply constrained by law | Environmental protection limits new development — structural floor under prices | Positive |
| Italian purchase bureaucracy | 3–6 month typical timeline — plan accordingly | Low |

Legal & ownership
The full pathway, step by step.
- 1
Ownership (fully transparent)
Italy operates under EU property law. Foreigners — EU and non-EU — can purchase freehold property with no restrictions. Title system is administered by the Agenzia delle Entrate and local Land Registry (Catasto). Full freehold title (piena proprietà) is standard.
Important for older properties: verify absence of undisclosed building modifications and incomplete planning authorisations — a persistent risk in renovated Sardinian properties.

- 2
STR compliance (mandatory from 2025)
Two codes now required in Sardinia:
- CIN (Codice Identificativo Nazionale) — national code, mandatory January 2025. Register via Ministry of Tourism portal. Must be displayed outside property and in all listings. Fines: €500–€5,000 for non-compliance.
- IUN (Identificativo Unico Nazionale) — Sardinia regional code, still required alongside CIN during transition.
⚠️ Nov 2024 safety update: gas/CO detectors mandatory, portable fire extinguishers mandatory, in-person guest check-in required (key boxes banned).
Sources: Investropa Sept 2025, Your Overseas Home Feb 2026, CIN Italy guide Nov 2025.
- 3
Tax obligations (2025–2026 rules)
- Cedolare Secca flat tax: 21% on rental income (first property) | 26% (second property onward) — from Jan 2025
- From Jan 2026: 3+ properties = presumed business activity → P.IVA (VAT) required
- IMU (property tax, non-primary residence): ~€1,500–3,000/yr typical villa
- Purchase taxes: 2% (primary residence) / 9% (secondary / investment) — on cadastral value, not market price
- Airbnb withholds 21% Cedolare Secca automatically on qualifying bookings
- Sources: Tuscanhouses Jan 2026, Your Overseas Home Feb 2026, GetProofSnap Mar 2026.
- 4
Purchase timeline
Italian property purchase is well-regulated but slow:
- Preliminary contract (Compromesso) + 10–30% deposit — legally binding
- Due diligence period: 4–8 weeks (title, planning, compliance)
- Final deed (Rogito) before notary — funds transferred
- Registration with Land Registry: 2–4 weeks post-completion
Total typical timeline: 3–6 months. Budget €2,000–3,000 for independent legal counsel.
- 5
Exit pathway
Full freehold, freely transferable. Strong secondary market in North Sardinia, especially San Teodoro, Arzachena and Olbia. Exit costs: ~5–7% (notary, registration taxes, agent). Capital gains: taxed at 26% if sold within 5 years of purchase; exempt after 5 years if primary residence.
