Innerrhoden pays the highest housing allowance

According to a recent analysis by Wüest Partner, Appenzell Innerrhoden tops the list of Swiss cantons with the highest risk of overvaluation for detached houses. Prices there are around 16 per cent above their fundamental value, but the small size of the market means this warning is susceptible to significant fluctuations.

This finding is based on two developments that are occurring simultaneously. On the one hand, according to Wüest Partner, detached houses in Appenzell Innerrhoden have seen the strongest growth in the whole of Switzerland between 2005 and 2025. On the other hand, the market remains small, meaning that individual transactions can skew the statistics more significantly than in larger centres.

For owners and prospective buyers, this is more than just an academic warning. When prices are significantly above fundamental values, there is an increased risk that sales will take longer, asking prices will need to be adjusted, or succession arrangements for older properties will become more difficult.

Attractiveness drives growth, demographics act as a brake
Wüest Partner cites the low tax burden, the region’s appeal to tourists, as well as demand for second homes and proximity to healthcare facilities as key drivers. This is consistent with the fact that, in 2026, the canton will still remain below the statutory 20 per cent limit on second homes, although the proportion has risen slightly in all districts. It is precisely this combination of tax attractiveness, landscape and specialised uses that can drive buyers’ willingness to pay beyond the locally determined level.

At the same time, the classification highlights structural weaknesses. Many jobs are located outside the canton, the population is comparatively older, and no major transport infrastructure developments are on the horizon. If more properties come onto the market in the coming years due to retirement, this additional supply will meet a location where demand is heavily dependent on special factors.

No crash signal, but a warning sign
This does not automatically indicate an imminent price collapse. Wüest Partner expects prices for detached houses to continue rising nationwide in 2026, despite slowing momentum, albeit at a significantly slower pace than before. This is precisely why Innerrhoden stands out. Contrary to the national trend of robust property prices, the canton is moving into a zone of heightened overvaluation. For the local housing market, this is not evidence of a bubble on the verge of bursting, but a clear indication of increased vulnerability to economic or demand shocks.
