The Saarlouis district is a rural administrative region located in the western part of Germany, within the state of Saarland. It covers an area of undulating terrain bordering the districts of Merzig-Wadern, St. Wendel, Neunkirchen, and the Regionalverband Saarbrücken.
Property prices across the district are generally lower than the German national average, though costs vary significantly between individual municipalities. The town of Saarlouis holds the largest portion of the local housing stock, followed closely by Lebach, with Saarwellingen and Dillingen also containing substantial shares. The most expensive homes are concentrated in Überherrn and the town of Saarlouis itself, where prices sit well above the regional average. In contrast, the market in Lebach is considerably more affordable, while Schmelz offers some of the cheapest housing in the district.
