The average price of apartments in Séné stands at 3 730 €/m², according to the DVF database, which records sales actually registered before notaries. A peninsula set on the golfe du Morbihan, at the southern gates of Vannes, Séné unfolds a string of maritime villages, marshes and coastal paths, among them the nature reserve of the marais de Séné. The market combines residential demand from Vannes and the appeal of the shore of the gulf. The price of a property there depends on closeness to the water and to Vannes, on the view, on the condition of the home, on its aspect and on the presence of outdoor space.

The Séné market is supported by residential pressure from the Vannes conurbation and by the appeal of the golfe du Morbihan. Houses close to the water and to the maritime villages find a buyer quickly, while properties further from the shore offer more measured prices and remain more negotiable.
The strength of Séné lies in its double nature, a preserved peninsula and a municipality of the Vannes conurbation. Its limits lie in the scarcity of land on the edge of the gulf and in coastal protection constraints that hold back supply. The municipality sits below the highly prized resorts of the coast, but above the inland municipalities of the Morbihan.
Séné sits at a level close to Vannes, below the highly sought-after resorts of the presqu'île de Rhuys such as Sarzeau and Arzon.
Séné is the country of the Sinagots, named after the sinago, the traditional boat with red sails that was used for transport and for fishing on the gulf. The municipality long lived from the sea, from the salt marshes and from oyster farming.
Its maritime villages, Montsarrac, Barrarach and Port-Anna, keep the memory of that activity. The former salt marshes have become the nature reserve of the marais de Séné, known for its birds.
Séné now has 9 554 inhabitants and has turned into a sought-after residential municipality of the Vannes conurbation, while preserving its coastal identity and its natural heritage.
