Sierck-les-Bains, 3-room apartment in converted attic, 2 bedrooms, 50 m² Carrez and 78 m² floor area, move-in ready, controlled expenses. 10 minutes from Schengen and the Luxembourg border, in the heart of the historic town of Sierck-les-Bains, I present a 3-room apartment in a converted attic, entirely ready to move into. Sierck-les-Bains is a small medieval town nestled in a bend of the Moselle River and dominated by the Castle of the Dukes of Lorraine. It features old streets, stone facades, shops, schools, a market and landscaped Moselle riverbanks. The location is strategic in the border triangle. Schengen is 10 minutes away, Perl and Germany 10 minutes, Remich and the Wine Route 15 minutes, Thionville 20 minutes and Luxembourg City 40 minutes. Malbrouck Castle, Rodemack and the Montenach nature reserve are in the immediate vicinity. The apartment occupies the converted attic on the top floor of a well-maintained historic stone building. Skylights bring in plenty of light and the volume is of the kind you don't find on a standard floor. No overlooking neighbors and no one above. It is ready to move into and there is nothing to renovate to settle in or to rent it out. The kitchen is open to the living room, fitted and equipped with induction hob, oven, extractor hood and refrigerator. The bathroom has a bathtub and space for a washing machine. The toilet is separate. Two proper bedrooms. Fiber optic, double glazing, mechanical ventilation, intercom and a storage room of 8 m² under the eaves for storage. A word on the surfaces, because three figures coexist and precision is necessary. The Carrez law surface is 50 m² and this is the legal surface of the deed. In an attic, Carrez law only counts what exceeds 1.80 m in height and therefore excludes all sloped ceilings. The floor area is 77.74 m² and this is the actual floor space, the space you occupy and which determines what you can install there. The weighted surface is approximately 64 m² and this is what is used for valuation. In other words, you are buying 50 m² on paper and you are living in nearly 78 m². The surfaces were measured on July 25, 2026 by a certified surveyor. The co-ownership is a real asset. It has only 10 main units, it is human-scale and is managed by MATERA property management with online access to accounts. The charges amount to 44.44 euros per month, approximately 535 euros per year, including maintenance fund and cold water. The property tax is 312 euros per year. No proceedings are underway, the roof is insulated and the common areas are in good condition. Heating is individual electric and hot water is provided by a water heater. There is therefore no collective heating charge and each resident controls their own consumption. This property is suitable for an investor seeking border rental income without any renovation costs, a first-time buyer wanting to enter the property market in an still affordable area, or a cross-border resident looking for a comfortable pied-à-terre a few minutes from Luxembourg.
