The places
Waterfront, mountain, city
The three kinds of prime asset behave differently in a cycle, cost differently to hold and sell to different people. Which one you are buying matters more than where.
Sardinia · Italy
Costa Smeralda
A coast planned as a private estate in the sixties and still run like one: fifty kilometres of granite and turquoise water with a consortium that decides what can be built, which is almost nothing. The most expensive villa market in Italy, by a distance.

Where exactly
Porto Cervo, Pantogia and the marina
The village the Aga Khan built and the hills behind it. The marina apartments are the entry; the villas on Pantogia with the view of the harbour are the address.
Romazzino, Cala di Volpe and Capriccioli
The bays south of the village: the hotel beaches and the villas above them, where the trophy sales happen. Frontline here is the top of the Italian market.
Porto Rotondo and Punta Lada
The second village, quieter, with its own marina and a buyer base that is more Italian than international.
Baja Sardinia, the Maddalena side and Palau
The northern arc, outside the consortium rules, with more variety and lower prices. The place to buy a villa that can be extended.
The short version
A coast with a committee
The Costa Smeralda works because nobody can build on it. The consortium founded in 1962 still controls the architecture of every house within its boundaries, from the roof pitch to the colour of the render, and the commune adds a coastal planning regime that makes new plots close to fictional. The result is a fixed stock of villas on the best coast in Italy, and a price for them that has doubled twice since the millennium.
It is a summer market in the purest sense. The restaurants, the beach clubs and the marina live for ten weeks and shut. Buyers who understand that the house is a July asset with a garden are the ones who keep their houses; the others sell to them after three years.
Off-market is the norm at the top, because the sellers are the kind of people who do not want to be seen selling, and because the three or four agencies that hold the coast know every buyer already. The desk registers a mandate here with evidence of funds before it asks to see anything.
Worth knowing
Registration tax
9 per cent of cadastral value; effective cost typically 3 to 5 per cent of the price
Consortium
Building and alteration within the Costa Smeralda are subject to the consortium's architectural committee, on top of the commune
Season
Ten weeks, June to early September; the coast is closed in winter
Letting
The highest weekly rents in Italy in August, a gross yield that still stays under four per cent against the price
Access
Olbia airport, forty minutes, with the private terminal that half the buyers use
Water
The island imports it in dry summers; cisterns and a well are part of the survey
Who is buying
Milan and Rome first, then the Swiss, Germans, British and, at the very top, buyers from the Gulf and from the United States who arrive by yacht and leave by jet.
What the desk is working on
Frontline in the bays between Porto Cervo and Cala di Volpe, villas on Pantogia with a harbour view, and anything on the coast that has a dock. The desk holds one whisper instruction on Romazzino for a house that has never been photographed.
Buying notes
Italian process: registered compromesso, ten to twenty per cent deposit, each side its own agent, nine to ten per cent all in. Every alteration, including a pergola, needs the consortium and the commune; check what consents the existing house holds, because a villa that was extended without them cannot be sold in that state.
The hotspot vote
On the Costa Smeralda
Questions buyers ask
Yes. The buyers here are not looking for value; they are looking for the coast their friends are on in August. What holds the value is that nobody else can build, and that is a stronger floor than a long season.
For the season, at rates that are the highest in Italy. A well-positioned villa earns its running cost in six weeks. The yield instrument with the Costa Smeralda profile and the honest number of weeks will tell you what is left.
It is the reason the coast still looks the way it does, and every buyer benefits from the rules that constrain them. Budget a year for any significant works and use an architect who has been through the committee before.
Cervo for the international life and the price; Rotondo for a quieter, more Italian summer and a lower entry. The bays between them are where the trophies sit.
