A B&B for sale in Seine-et-Marne sits between the forest of Fontainebleau, the ramparts of Provins and the Loing and Grand Morin valleys, and draws guests well beyond the summer months. Parisians come for weekends in Barbizon, Moret-sur-Loing or at the château of Vaux-le-Vicomte; climbers head for the sandstone boulders of the forest; overseas families stay near the theme parks of Marne-la-Vallée; business travellers want a quiet room between Roissy airport and the eastern suburbs.
Properties range from a bourgeois house in its own grounds to a mill combining guest rooms, gîtes and space for events. This page is for buyers of a running chambres d'hôtes business (the French term for a B&B run from the owner's home), for people comparing Seine-et-Marne with guest houses in Yvelines, and for owners planning to sell.

These figures put a guest house above the ordinary market: half of all country houses in Seine-et-Marne sold for under €250,600 in 2025, with 112 m² of living space on average, and the top decile starts at €376,344. A home large enough for five letting rooms, with grounds and outbuildings, belongs to the prestige segment, where the department median is €785,000 over 2021-2025, well below the regional figure of €1,263,100. The few sales in tourist inland villages, around €215,000, are only indicative.
In the south, the forest of Fontainebleau, Barbizon, Moret-sur-Loing and the Loing valley towards Nemours attract walkers, climbers and art lovers. In the south-east, Provins, a UNESCO World Heritage site, brings short-break visitors to its medieval upper town. In the north, Meaux and the Marne valley border the Roissy and Marne-la-Vallée business areas, where bookings spread across the year. In the east, the Brie plateau and the Grand Morin valley around Crécy-la-Chapelle and Coulommiers offer large farmhouses at gentler prices, with a more seasonal trade. Access is by the A4, A5 and A6 motorways, Marne-la-Vallée–Chessy high-speed station, Charles de Gaulle airport and suburban trains to Fontainebleau, Provins and Meaux.
Local properties are courtyard farms, barns in limestone or millstone rubble, bourgeois houses and, in the south, sandstone buildings: roofs, floors and insulation often need work. The Seine, Marne, Loing and Morin valleys are flood-prone, so check the flood risk plan before buying a mill or riverside house; plateau clays can also shrink and swell. A chambres d'hôtes business is limited to 5 rooms and 15 guests at a time, breakfast included, and must be declared at the mairie (town hall); above that, the building is treated as a public venue. Serving wine at the table d'hôtes, the evening meal shared with guests, requires at least a restaurant licence and a specific permit. See our guide to opening chambres d'hôtes (in French).
Two land-registry benchmarks frame most projects: €250,600 for a country house in 2025 and €785,000 for a prestige home over 2021-2025. A mill or a property with grounds, outbuildings and an events room sits closer to the second figure. Add purchase costs, compliance work, room fit-out and working capital for the first season.
Paris, the theme parks and the business districts fill rooms on weekdays as well as weekends, which evens out the season, but purchase prices are higher and hotel competition is dense. Test your assumptions with our B&B profitability and tax simulator (in French), then have an accountant review them.
The sale covers the property itself, signed before a notaire (the public official who handles property sales) after a compromis de vente, or preliminary contract, and usually the furniture, booking website and forward bookings. Our guest house buying guide (in French) covers each step. Owners can list their property with us.
