Apartments in Saint-Sébastien-sur-Loire sell at an average price of around 3 248 €/m², based on prices actually recorded (DVF data, the French notarised sales database). A town of Nantes Métropole set on the south bank of the Loire, about 4 km from the centre of Nantes, it stays below the Nantes price while sitting above the other towns of the south bank. Prices run from around 2 802 €/m² in La Martellière, to the west, to nearly 3 607 €/m² in L'Ouche Quinet, to the south, setting aside La Joliverie, whose average rests on a very small number of sales. The Centre sits at around 3 357 €/m². Houses, at about 3 454 €/m², trade above apartments: the town was built after the war as a garden suburb of detached houses, and the market still carries that mark.

The average price per m² for an apartment in each district of Saint-Sébastien-sur-Loire covered by Immover, ranked from the most expensive to the most affordable.
The Saint-Sébastien-sur-Loire market is that of a residential town in the inner ring, backing onto Nantes and part of the metropolitan area. With an average price of around 3 248 €/m² for an apartment, Saint-Sébastien-sur-Loire sits below Nantes, at 3 471 €/m², but clearly above the other south-bank towns covered by Immover, such as Rezé, at 2 683 €/m². Houses, at around 3 454 €/m², trade above apartments: detached houses dominate both the stock and demand.
The trend is flat. Apartments gain around 1 % over twelve months and 1 % over five years, with a marked peak in 2022 and 2023 followed by a return to the 2021 level. Gaps between districts stay contained, from 2 802 €/m² in La Martellière to 3 607 €/m² in L'Ouche Quinet, excluding La Joliverie, whose volume is too small to be read as a trend. With about 197 apartment sales a year in a town of 28 600 inhabitants, the market is liquid and the town-wide average reliable.
With an average price of around 3 248 €/m², Saint-Sébastien-sur-Loire is more affordable than Nantes while remaining one of the most expensive towns on the south bank. Its position a few minutes from the centre of Nantes, its two tram-train stops and its setting of detached houses by the Loire make it a sought-after town for families across the metropolitan area.
Saint-Sébastien-sur-Loire occupies the south bank of the Loire, facing the islands and only a few kilometres from the centre of Nantes. The village was called Aigne before taking, in the fifteenth century, the name of the pilgrimage to Saint Sebastian that had settled there. Long agricultural and turned towards the river, the town lived on vines, market gardening and work on the Loire.
The arrival of the Cassegrain food factory in 1856 marks the start of the industrial era. The church of Saint-Sébastien, rebuilt between 1868 and 1875, fixed the centre. The manor of La Jaunaie, to the east, keeps the memory of the treaty signed in 1795 during the Vendée wars. After 1945 the town turned into a garden suburb: estates of detached houses replaced the fields, and the population went from a few thousand to nearly 28 600 inhabitants today.
The geography of prices follows that history. The areas of the south and south-east, around L'Ouche Quinet and La Profondine, hold the top of the market with recent estates and small condominiums. The Centre and La Métairie, to the north, concentrate most of the apartment sales and stay close to the average. La Martellière, to the west towards the Nantes boundary, closes the ranking. Immediate proximity to Nantes, the two tram-train stops and the 140 hectares of natural space on the Loire islands shape demand.
The Saint-Sébastien-sur-Loire market attracts families and working people from Nantes looking for a residential town without leaving the metropolitan area, as well as first-time buyers willing to move a little away from the centre of Nantes for a more manageable budget. Demand covers both the houses of the estates and the apartments of the small condominiums of the centre and of more recent schemes. The schools, the René-Bernier secondary school, the La Joliverie campus, the banks of the Loire and direct access to the centre of Nantes in under ten minutes by tram-train support an active market.
The average price in Saint-Sébastien-sur-Loire is 3 248 €/m² for an apartment (actual DVF transactions, notarised sales), within a range of 2 775 to 3 594 €/m² depending on the district. Property portals show asking prices, 10 to 20 % above the prices actually recorded.
No. Setting aside La Joliverie, whose average of 4 572 €/m² rests on only four sales a year and is therefore not representative, L'Ouche Quinet shows the highest prices, at around 3 607 €/m², while La Martellière, to the west, remains the most affordable area, at around 2 802 €/m². The Centre sits at around 3 357 €/m² and La Baugerie, the most active district in the town, at around 3 214 €/m².
The town borders Nantes directly, on the south bank of the Loire, with two tram-train stops that put the centre of Nantes less than ten minutes away, the busway line 4, the Chronobus C9 and two ring-road junctions. It offers a setting of detached houses, the Loire islands and the Gripôts woods, and an average price of around 3 248 €/m² for an apartment, below the Nantes level.
No, the market is stable. Over twelve months apartment prices rise by around 1 %, and over five years the increase is of the same order: after a peak in 2022 and 2023, levels have come back down to those of 2021. With about 197 apartment sales a year, the town-wide average is solid, even if that of some districts rests on few transactions.
The town-wide average price is not enough: you have to start from the price in your own district, then adjust for the type of property, the floor area, the floor, the condition, the aspect and the distance to public transport. The gap is wide between a studio, at around 4 095 €/m², and a large four-room or bigger flat, at around 2 850 €/m². The Immover valuation tool draws on the actual sales closest to your address.
