There are no statistics dedicated to farmhouses and barns: a renovated farmhouse sells like a country house with outbuildings and land, whereas a bare barn or a farm to renovate often sells well below. The most useful benchmark therefore remains the price of country houses.

A departmental average hides large gaps. A smallholding to renovate, a restored longère with its outbuildings, a farmhouse on several hectares of land or a manor house with parkland do not sell at the same price, and the location matters as much as the building: coastline, tourist area, peri-urban countryside close to a job market or deep countryside. The table below shows the median price of country houses in Seine-et-Marne (77) by type of municipality (cumulative sales from mid-2020 to 2025) and its change between 2021 and 2025.

The typical Brie farmhouse is a courtyard farm: the dwelling, a monumental barn, a cowshed, stables and sheds are arranged around a large square courtyard closed off by a gateway. Towards the Gâtinais and Multien areas, more modest versions exist, but the scale is often imposing, a legacy of historically large cereal farms. There are no mas in Seine-et-Marne; the term has no local roots here.
These sizeable volumes lend themselves to conversion into a home, into gîtes or into a business, but require a project matched to the scale of the building: a barn of several hundred square metres still needs planning zoning approval for any change of use. The surrounding farmland, which can run to several dozen hectares, remains in demand from working cereal farmers.
The Multien and Brie areas around Meaux and Coulommiers hold large open-field courtyard farms. Around Provins and the Gâtinais, near Nemours and Montereau-Fault-Yonne, prices stay more affordable than in the north-west of the department. The Loing valley, between Moret-sur-Loing and Nemours, mixes farm buildings with villages of character.
Near Melun and the Fontainebleau forest, as well as close to fast rail lines to Paris, renovated farmhouses are rare and noticeably more expensive. In French Brie, around Crécy-la-Chapelle, closeness to Paris also weighs heavily on prices.
Check the change of use of the building: in an agricultural zone of the local plan, a cereal-farm barn only becomes habitable if it is listed among the buildings identified for that purpose, which stays strict in a large-scale cereal-farming department. Check the roof (machine-made tile, slate, sometimes asbestos-cement on newer metal sheds), the timber frame and the drainage.
If farmland is attached, be sure to ask about any current farm lease, very common in this department, and about the pre-emption right of the Safer. Renovating a large-volume barn, silos and old tanks included, often calls for a bigger budget than the purchase itself.
