Buying property in Sardinia is, on paper, refreshingly simple: sign a contract, transfer funds, and take the keys. In practice, the transactions that go smoothly are the ones where a buyer treated every stage of the process as a legal decision, not just a financial one. This guide walks through what that looks like — and where the process can quietly go wrong for buyers who don’t know what to check for.
If you are researching buying property in Sardinia, chances are you have already found glossy listings for coastal villas and inland stone cottages. What is harder to find is a clear account of the legal groundwork that protects you before you commit a deposit. That is what this guide is for.

Can foreigners buy a house in Sardinia?
Yes — for the vast majority of foreign nationals, there is no legal barrier to owning property in Sardinia or anywhere else in Italy. EU citizens buy under the same conditions as Italian nationals, and most non-EU citizens can buy too, subject to a principle called reciprocity (condizione di reciprocità).
Reciprocity means Italy will allow a foreign national to buy property here if their home country grants Italian citizens equivalent purchasing rights. For citizens of the United States, United Kingdom, Canada, Australia and most Western nations, this is not an obstacle in practice. For a smaller number of countries, restrictions or additional conditions can apply, and this needs to be verified case by case, not assumed.
This is the first place we see a pattern that repeats throughout this guide: buyers assume that “yes, I am allowed to buy” is the same as “yes, I am safe to buy.” It isn’t. Confirming legal eligibility is step one of due diligence, not a footnote — and it is exactly the kind of check that should happen before you fall in love with a specific property, not after.
Why Sardinia attracts foreign buyers (and why that demand creates risk)
Sardinia’s appeal is easy to understand. Coastal areas like the Costa Smeralda command premium prices and international name recognition, while inland regions — the Barbagia, the Gallura hinterland, villages across the Ogliastra — offer far lower price points and a growing following among lifestyle buyers and remote workers.
That range of demand is precisely what creates risk. Popular coastal zones see intense competition among buyers, which can pressure people into skipping proper checks to secure a property quickly. Inland and rural areas, meanwhile, often have lower transaction volumes and less market scrutiny — which means unauthorised building work, unclear boundaries, or unresolved inheritance issues can go unnoticed for years before a buyer stumbles into them.
In both cases, high demand and low local competition among buyers — not sellers — can translate into less rigorous scrutiny of title, planning permission, or informal construction than most purchasers assume is standard. A fast-moving market is not a reason to move fast on the legal side. It’s a reason to move faster on securing independent advice.
What is the legal process for buying a house in Sardinia?
The purchase process in Italy follows a fairly consistent structure, but each stage carries its own legal weight — and its own risk if rushed.
Making an offer and signing the proposta d’acquisto
The process typically begins with a proposta d’acquisto (purchase proposal), a written offer specifying the price and key terms. Once the seller accepts it, the proposal becomes binding, usually accompanied by a small deposit.
This is an easy stage to underestimate. Buyers sometimes treat the proposta as an informal expression of interest, when in fact it can already create binding obligations. Legal review at this point — not after — is what prevents a rushed offer from becoming a costly commitment.
The preliminary contract (compromesso) — what it actually locks you into
The compromesso, or preliminary contract, is where the transaction becomes serious. It sets out the final price, the completion timeline, and the conditions of sale, and it is typically backed by a substantial deposit — often 10–20% of the purchase price.
Crucially, the compromesso is legally binding on both parties. If the buyer withdraws without a valid contractual reason, the deposit can usually be forfeited. If the seller withdraws, they may be required to pay back double the deposit. This is precisely why the compromesso should never be signed without a lawyer having reviewed the property’s legal status first — by this stage, walking away has a price.
Due diligence: title, cadastral records, and planning compliance
Between the proposal and the preliminary contract — ideally before either is signed — proper due diligence should confirm:
- That the seller holds clear, undisputed title to the property
- That the cadastral records (catasto) match the physical property
- That all structures on the property have valid planning permission
- That there are no outstanding mortgages, liens, or legal disputes attached to the property
Skipping this step is the single most common source of post-purchase disputes in Italian property transactions, and Sardinia is no exception.
Signing the deed of sale (rogito) before a notary
The final step is the rogito notarile, the deed of sale signed before a notary, at which point ownership formally transfers and the balance of the purchase price is paid. It is worth understanding clearly what the notary does and does not do for you.
The notary is a neutral public official whose role is to verify the formal legality of the deed and register the transfer — not to negotiate on your behalf, assess whether the price is fair, or protect your individual interests as the buyer. That is the role of your own lawyer, working independently of the notary and the seller’s estate agent throughout the process, not just at the final signing. (See our guide to the role of the Italian notary for more detail.)
Do you need a codice fiscale to buy property in Sardinia?
Yes. A codice fiscale — an Italian tax code — is mandatory for any foreign buyer purchasing property in Italy, including Sardinia. It is required to sign the preliminary contract, open an Italian bank account if needed, and complete the deed of sale.
Obtaining one is usually straightforward, but this is an area where small administrative errors regularly cause delays at closing. The most common issues we see include:
- Date formats submitted incorrectly (Italy uses day/month/year, which trips up buyers used to other conventions)
- Name mismatches between a buyer’s passport and other identity documents
- Applications submitted through an Italian consulate without allowing enough processing time before the planned signing date
None of these are complicated problems, but discovered on the day of signing, they can delay a closing that everyone had planned around. Applying early, and having a lawyer check the details before submission, avoids this entirely. (Full details in our codice fiscale guide.)
Please be aware that rectifying an incorrect fiscal code appearing in the purchase deed costs no less than euro 1.000 (one thousand)
What are the risks of buying property in Sardinia without a lawyer?
This is the section that matters most, because the risks here are not hypothetical — they are the recurring reasons foreign buyers lose deposits or inherit disputes after closing.
Abusivismo edilizio (unauthorised construction) is the largest risk specific to the Sardinian market. Extensions, verandas, pools, or entire outbuildings added without the correct permits are common, particularly in older coastal and rural properties. A structure built without permission can be difficult or impossible to sell on, and in some cases can expose the new owner to fines or demolition orders — even though the buyer had nothing to do with the original construction.
Unclear boundaries in rural land is a related and frequent problem inland. Cadastral maps do not always match physical boundaries on the ground, particularly for older rural parcels, and disputes with neighbouring landowners can surface only after purchase.
Inherited or co-owned properties with unresolved title are another recurring issue. Many Sardinian properties, especially in villages and rural areas, have passed through generations without formal succession being completed. This can mean multiple heirs technically hold a share of the property — and unless all of them are party to the sale, the buyer’s title is not secure. (Where this overlaps with succession planning, our estate administration and inheritance guide covers the process in more depth.)
Independent legal representation exists specifically to catch these issues before they become the buyer’s problem. This is not a formality layered onto the transaction — it is the mechanism that protects the deposit already paid and prevents disputes from surfacing after the deed is signed, when options for recourse are far more limited.
If a property you’re considering has any of these red flags, informal building work, unclear boundaries, or multiple heirs, it’s worth having it reviewed before you go further. Speak with our team about a pre-purchase legal check.
How much does it cost to buy a house in Sardinia?
The advertised sale price is rarely the full cost of buying property in Sardinia. Budgeting accurately means accounting for taxes and fees on top of the purchase price, which can add a meaningful percentage to the total.
Typical costs include:
- Registration, cadastral, and mortgage tax (or VAT, depending on whether the seller is a private individual or a business — the applicable regime changes the tax treatment significantly)
- Notary fees, generally calculated on a sliding scale relative to the property value
- Estate agency fees, if a real estate agent was involved, typically 3–5% plus VAT
- Legal fees, for due diligence and contract review
The gap between the advertised price and the real total cost is where many buyers are caught off guard — not because the individual costs are hidden, but because nobody added them up for them in advance. A lawyer can model the full cost of a specific property before any binding contract is signed, so the number you agree to is the number you can actually afford.
Do you need a mortgage or can you buy in cash?
Both financing routes are available to foreign buyers, though Italian banks assess non-resident applicants differently than they do Italian residents — typically requiring a larger deposit, more extensive documentation, and a longer approval timeline.
Cash purchases are common among foreign buyers in Sardinia, particularly given current market conditions, and they simplify the timeline considerably. If financing is involved, however, timing becomes a legal issue as much as a financial one: the preliminary contract sets a completion deadline that does not automatically extend if a mortgage approval runs late.
This is why mortgage timelines should be factored into the compromesso itself — ideally with a financing condition built into the contract — rather than treated as a parallel process that the legal side has to work around after the fact.
What happens after you buy — taxes and obligations as a foreign owner
Closing on the property is not the end of the legal relationship with Italian bureaucracy — it is the start of an ongoing set of obligations.
Foreign owners should be aware of:
- IMU (the Italian municipal property tax), payable annually, with the rate depending on whether the property is a primary residence and the specific municipality
- Residency implications, since spending extended time in Italy can affect tax residency status depending on individual circumstances
- Rental rules, if the property will be let out, including registration requirements and applicable tax treatment on rental income
None of these require constant attention, but each has deadlines and rules that differ from what buyers may be used to at home. Treating post-purchase compliance as part of the same relationship that handled the purchase — rather than a separate problem to solve later — tends to prevent small administrative lapses from becoming costly ones.
How De Tullio Law Firm helps foreign buyers purchase safely in Sardinia
De Tullio Law Firm represents buyers — independently of the notary and independently of the estate agent — at every stage of a Sardinia property purchase. That distinction matters: neither the notary nor the agent is working exclusively in your interest, and a transaction this significant deserves someone who is.
Our role typically includes:
- Verifying legal eligibility and reciprocity conditions before you make an offer
- Conducting full due diligence on title, cadastral records, and planning compliance
- Reviewing and negotiating the terms of the proposta d’acquisto and compromesso
- Flagging unauthorised construction, boundary issues, or unresolved inheritance claims before they become your liability
- Calculating the full cost of a purchase, taxes and fees included, before you sign anything binding
- Acting under power of attorney to represent buyers who are unable to travel to Italy for signing
Whether you are drawn to a coastal property on the Costa Smeralda or a stone house in an inland village, the legal groundwork is the same: verify before you commit, not after.
