Estate agent in Rothenthurm: selling your house or flat

Selling in Rothenthurm

Of the 564 buildings with residential use in Rothenthurm, 246 are apartment buildings (Mehrfamilienhäuser) and 211 are detached houses (2025). Of these buildings, 249 date from before 1981, and 146 were added after 2000. Three cases follow from this:

• An older house. At 923 m above sea level, buyers ask first about heating, windows and insulation.
• A flat in a newer apartment building. What counts are the regulations, the renewal fund and the view.
• A second home (Zweitwohnung) or an inheritance. Around one dwelling in ten counts as a second home.

In our assessment, the buyers are families from the region, joined by newcomers from the Ägeri valley and from Lake Zurich who are looking for more space for their budget. It starts with the valuation.

What makes Rothenthurm special

Rothenthurm lies in the high valley of the River Biber, with the village centre at 923 m above sea level. The municipality covers 2,275 hectares; it comprises the linear village along the road, the hamlets of the Altmatt, and Biberegg. The building zone takes up 2.6% of this area. North of the village centre begins the Rothenthurm mire landscape (Moorlandschaft), site no. 1 in the federal inventory. Its neighbours are Oberägeri, Einsiedeln, Alpthal, Schwyz and Sattel.

The name comes from the tower of the Letzimauer, a defensive wall built around 1310 during the Marchenstreit, the boundary dispute between Schwyz and Einsiedeln Abbey.

How Rudat AG sells in Rothenthurm

In 2026 we handled two mandates in Rothenthurm. A detached house with 7.5 rooms at Altmattstrasse 7 was let about one month after the mandate began. A 4.5-room terrace flat with mountain views at Lützelmattstrasse 17 has been reserved since September 2026, marketed with 25 photos, a 360° virtual tour (in German) and sales documentation.

We derive the value with IAZI/CIFI, check it in the house itself and set out the reasoning in writing; professional photos, drone images, the property portals and the buyers registered with us then follow.

In Arth we have marketed the Hotel Felchlin on Rigi Staffel (in German); it has been reserved since October 2026. Our 26 Google reviews give an average of 5.0 stars.
