Buying Property in Sardinia as a Foreigner: Costa Smeralda and the Other Island

Published on: August 17, 2026

Last verified: 17 August 2026. Price ranges are segment reporting from the named sources, not a valuation of any specific property.

Quick answer: Sardinia is two markets. Porto Cervo and the Costa Smeralda core run roughly 8,000 to 15,000 euros per square metre for new luxury villas, with seafront above 20,000; inland Sardinia runs roughly 2,000 to 3,000. Foreigners buy freely, subject to Italy's reciprocity condition for non-EU buyers without an Italian residence permit, and need a codice fiscale. Total purchase costs run about 10% to 15% for a second home, and the prezzo-valore mechanism, which bases registration tax on cadastral rather than purchase value, is the single biggest saving most foreign buyers never ask for. The two island-specific risks are the 300-metre coastal building constraint and planning and cadastral conformity on properties that have been extended.

Sardinia is two property markets that happen to share an island, and confusing them is the fastest way to waste a year of searching.

One of them is the Costa Smeralda, a compact stretch of the Gallura coast where a new villa in the right position costs more per square metre than central Milan. The other is everything else: an island roughly the size of Wales with an interior of granite villages, a second and third coastline that most foreign buyers never look at, and prices that sit closer to rural Puglia than to Porto Cervo.

This guide covers both, plus the two things that catch foreign buyers here specifically: the coastal building constraint, and Italian planning compliance.

The price picture, honestly

Published averages for Sardinia diverge sharply, and you should know why before you use any of them.

Both are "the average price in Sardinia." Neither is wrong. The island's price distribution is so skewed that the average tells you almost nothing about any specific place. Work from the local figures instead.

What things actually cost, by area

Who is buying

Italy's foreign residential market reached roughly 5.5 billion euros in 2025 on Scenari Immobiliari's estimate, up about 10% on 2024 and around 48% above 2019, the strongest decade figure. Sardinia's share of Italy's international demand has risen from roughly 1% to about 9% over ten years.

German buyers dominate foreign demand on the island by a wide margin, with North American and British buyers well behind. That is worth knowing for two reasons: it shapes which agencies have real international reach, and it means your eventual resale market is probably German. Our map of where German buyers go abroad puts that in context.

Can a foreigner buy? The reciprocity rule

There are no foreign-ownership caps in Sardinia and no restricted zones for residential purchase. But Italy applies a rule most guides skip.

EU and EEA citizens, and non-EU citizens who hold a valid Italian residence permit (or one of certain long-term EU permits), buy without restriction.

Non-EU citizens without an Italian residence permit buy under the condizione di reciprocita: Italy permits purchase where the buyer's own country would permit an Italian to buy there. In practice this is satisfied for the United States, United Kingdom, Canada, Australia, Japan and most major markets, and the Ministry of Foreign Affairs maintains the reference. Your notaio verifies it. It is a checkbox for most buyers, and a genuine obstacle for a small number of nationalities, which is why it is worth raising in the first conversation rather than the last.

You will also need an Italian codice fiscale (tax code) before you can do anything, obtainable from the Agenzia delle Entrate or an Italian consulate. See the tax number you need to buy property abroad for the sequence.

The Sardinia-specific issue: the 300-metre coastal band

If you take one thing from this guide, take this.

Italian national law (Legislative Decree 42/2004, article 142) designates the coastal strip 300 metres from the shoreline as a landscape-protected area. Sardinia layers stricter regional protection on top: regional laws dating to 1989 and 1993 established a building constraint in that band, and the Piano Paesaggistico Regionale (PPR), adopted in 2006, extended and specified coastal protection across the island.

What this means for a buyer:

• Within the 300-metre band, new construction is heavily constrained outside already-urbanised areas, and works that are permitted require autorizzazione paesaggistica on top of ordinary planning consent.
• The PPR's mapped 300-metre boundary is expressly cautionary rather than definitive. The regional norms state that the actual position of the constrained band must be verified case by case for any specific intervention. In other words, a map showing your plot just outside the line is not a clearance.
• Demolition and reconstruction within the band is governed by specific regional guidelines aimed at reducing landscape impact, not by ordinary rebuilding rules.
• The regulatory history here is contested. Regional attempts to loosen coastal building rules have repeatedly been challenged, and the Constitutional Court has intervened, in 2022 among other occasions, reaffirming the coastal strip's protected status. Anyone selling you a plot on the promise of a rule change should be treated with scepticism.

The practical rule: if the property is anywhere near the coast and any part of your plan involves building, extending, or rebuilding, commission a certificato di destinazione urbanistica and a technical report from an independent local geometra or architect before you commit. Not the seller's. Yours. The same principle applies to coastal setback rules everywhere, as covered in coastal ownership and setback laws.

The second Sardinia-specific issue: planning compliance

Italy has a long history of abusivismo edilizio, construction carried out without permits or in departure from them, followed by periodic amnesty (condono) programmes. Sardinia has more of this than most regions, particularly in coastal and semi-rural areas.

The consequences are concrete. Under Italian law, a seller must declare urbanistic and cadastral conformity at the deed. Where the building as it stands does not match the filed plans and permits, the sale can be blocked, the deed can be exposed to challenge, and the buyer can inherit an unresolvable position. Extensions, closed-in verandas, converted outbuildings and added floors are the usual culprits, and none of them are visible in listing photographs.

Your due diligence should include:

• Visura catastale and the planimetria catastale, checked against what physically exists.
• The building permit history (concessione edilizia or permesso di costruire), and any condono applications, including whether they were actually concluded.
• Agibilita or abitabilita certification.
• Any vincolo (constraint) affecting the property: landscape, archaeological, hydrogeological.

For an old stone house inland this is routine work. For a coastal villa with a history of additions, it is the whole transaction. Our guide to whether an overseas property is actually legal covers the southern European pattern in full.

The purchase process

1. Proposta d'acquisto. A written offer, usually with a small deposit. Once accepted it is generally binding, so do not treat it as an expression of interest.
2. Contratto preliminare (compromesso). The binding preliminary contract, with a caparra confirmatoria typically 10% to 30%. If you pull out you lose it; if the seller pulls out they owe double. Registering the preliminare (trascrizione) at the land registry protects you against the seller dealing with the property in the interim, and is strongly advisable on off-plan and long-completion purchases.
3. Due diligence. Title, mortgages and charges, planning and cadastral conformity, landscape constraints, and any pre-emption rights (agricultural neighbours and cultural-heritage authorities both hold them in defined cases).
4. Rogito. The final deed before a notaio, who is a public officer acting for the transaction rather than for either party. The notaio checks title and collects the taxes. As in France, you can and often should instruct your own independent lawyer alongside.

You can complete without being in Italy, via a notarised and apostilled power of attorney. Budget six to twelve weeks from preliminare to rogito on a straightforward purchase, longer where planning issues surface.

Purchase costs and the prezzo-valore saving

Total transaction costs generally run 10% to 15% of the price for a second home, less for a qualifying primary residence.

Buying from a private seller

Buying from a VAT-registered developer

VAT replaces registration tax: 10% on residential property, 22% on properties in the luxury cadastral categories (A/1, A/8, A/9), or 4% for a qualifying prima casa, with mortgage and cadastral taxes at 200 euros each.

The prezzo-valore mechanism

This is the most valuable thing an uninformed foreign buyer misses.

Where an individual buys residential property from an individual, Italian law allows the buyer to request that registration tax be calculated on the property's cadastral value rather than the actual purchase price. Cadastral values in Italy are typically far below market value, so the saving is often substantial. The mechanism must be requested at the deed, and it also reduces the notaio's fee scale.

It does not apply to purchases from VAT-registered developers, or to non-residential property. Ask your notaio to apply it explicitly. It is not automatic and no one will volunteer it.

Owning and letting

IMU. The annual municipal property tax applies to second homes, at rates set by each comune within national bands, on cadastral value. A qualifying prima casa in a non-luxury category is exempt. Most foreign buyers will pay it.

Short-term letting. Two things changed recently and both bind:

• Every short-let property must display a CIN (Codice Identificativo Nazionale), the national identification code introduced under the 2024 tourism reform and enforced from 2025. Platforms require it.
• Cedolare secca, the flat-rate regime on residential rental income, applies at 21% on one property and 26% from the second short-let property onward, under the 2024 Budget Law. Choose which property gets the 21% rate deliberately.

Sardinian comuni have also been tightening local rules on tourist accommodation, and municipal tourist taxes apply. Check the specific comune, not the region. Our comparison of furnished rental tax regimes sets cedolare secca beside its French and British equivalents.

Seasonality is the real yield constraint. Northern Sardinia's rental season is short and intense, roughly June to mid-September, with a sharp shoulder-season fall-off. Gross yield calculations built on a peak-week rate multiplied by a full year are meaningless here. Model the actual weeks.

Choosing an area

Costa Smeralda and Gallura if you want established international infrastructure, marinas, Olbia airport twenty minutes away, and the strongest brand recognition on the island. You are buying a mature and, by several accounts, currently saturated market: the price already reflects the name. Best for use, weakest for value discovery.

Ogliastra and the east coast for the largest gap between landscape quality and price, at roughly half the Gallura level or less. Fewer flights, longer transfers, thinner services outside season. This is where the value argument on the island currently sits, and it is also part of the Sardinian Blue Zone, which brings its own slow but real stream of international interest.

The south (Villasimius, Pula, Chia) for Cagliari airport access, a longer season, and a market with more year-round life than the northern resorts.

Alghero and the northwest for a genuine walkable town with Catalan heritage, an airport, and the island's most established Northern European retiree community.

Inland for the lowest entry prices anywhere, including the one-euro house schemes run by comuni such as Ollolai and Nulvi. Those come with binding renovation commitments and timeframes; the realistic all-in spend is tens of thousands of euros, not one. They are a project, not a bargain.

Frequently asked questions

Does buying property in Italy give me residency?
No. Property purchase confers no residence right. Italy's investor visa route is a separate programme based on qualifying financial investments, and real estate does not qualify for it. Non-EU owners remain subject to Schengen 90/180 unless they hold a long-stay visa such as the elective residence visa.

Are there private beaches in Sardinia?
Essentially no. The Italian shoreline is demanio marittimo, public maritime domain. A villa can have direct access and a concession-operated beach club nearby, but it does not own the beach. Any listing implying private beach ownership deserves careful scrutiny.

Can I get an Italian mortgage as a non-resident?
Yes, from several Italian banks, typically at 50% to 60% LTV for non-residents, with substantial documentation. Rates and terms are less favourable than for residents. Many foreign purchases in the top segment are cash.

Is Sardinia overpriced right now?
Island-wide asking prices sit close to, and by one index still slightly below, the previous cycle peak of 2012, which is not the pattern of an overheated market. The Costa Smeralda core is a separate case: it is a mature luxury market where scarcity and brand do most of the pricing work, and where recent commentary leans toward saturation. Those two statements can both be true because they describe different markets.

What is the biggest risk specific to Sardinia?
Planning and landscape compliance on coastal property. Almost every serious problem foreign buyers hit on this island traces back to a building that does not match its permits, or a plot whose coastal constraint was misrepresented.

How much should I budget above the purchase price?
For a second home from a private seller, budget 12% to 18% before any renovation, and considerably more if the property needs real work. Renovation costs on the coast run well above inland rates because of logistics, seasonality and contractor scarcity.
