Dordogne is also called Perigord and comprises four areas: Perigord, Vert, Perigord Blanc, Perigord Noir and Perigord Pourpre.
The Perigord Vert, located in the northern part of the Dordogne has wild landscape made up of greenery due to its humid climate. This area of Dordogne is very rural, with plenty of space and few inhabitants, large tracts of woodland and uncultivated land. The Perigord Vert is the cheapest part of the Dordogne with well known towns and villages such as Nontron, La Coquille, Riberac and Excideuil. You could get a partly (or fully) renovated farm house with few acres of land and maybe an outbuilding with a budget of 120 to 150.000 euros.
Further south you will find the Perigord Blanc which gains its name from its limestone plateaux. This area is home to a medieval town called Perigueux, which is the capital of Dordogne. You could also visit Hautefort. With a budget of 200.000 euros you can afford a Perigourdine style house with nice amount of land and 3 to 4 bedrooms.
The Perigord Noir in the southeast of Dordogne is the most famous part of the four. It has numerous medieval villages and castles, many of which are situated on the high rocky banks of the Dordogne River, which in great winding curves meanders through oak, walnut and chestnut forests. The prehistoric cave paintings are the absolute highlight of Perigord Noir, remarkable not only for their great age, but also for their exquisite colors and the skills used to drawn them. In Perigord Noir you can visit Sarlat la Caneda and Thenon. You can find a fully renovated French style stone house with 3 to 4 bedrooms and 1 acre of land will cost you around 185.000 euros.
Finally, the Perigord Poupre, so called due to its famous vineyards, which produce some of the best wines in France, has a very different landscape with numerous vineyards, tobacco and maize fields. In this area, a converted stone barn with woodland garden and garage will cost around 250 000 euros.
