Selling property in Dachsen: a median with no comparison year

Because a trend needs figures for two years, and Dachsen only supplies one of them. In 2025, 26 sales were enough for an official median of CHF 957,500, well above the threshold of 15.² For houses, the 10 sales were not enough. Of the 38 municipalities in the canton with fewer residents than Dachsen, only two have a flat median of their own for 2025.⁴

In 2015 there were only 6 sales, in 2007 there were 14, both below the threshold.² Without a second year, no change can be calculated from the figure alone, only a single snapshot.

For the ten-year worked example, the flat median of Andelfingen district is needed instead, since it covers both 2015 and 2025. Dachsen's own median of CHF 957,500 sits above the 2025 district figure of CHF 900,000. That is a clue, but no substitute for a valuation of your own property.

A different figure with a different method. The cantonal model puts residential building land in Dachsen at CHF 906 per square metre for 2025. In 2015 it was CHF 560.⁷ That is a rise of 61.8 per cent in ten years. Typically the model ranges from CHF 640 to CHF 1,291 per square metre.

For the canton as a whole there is a second measure. Residential building land actually sold for a median of CHF 1,742 in 2021 to 2025.⁷ Model value and sale price are produced in different ways. Dachsen sits well below this cantonal figure on its model value.

The model only estimates undeveloped land, not your own plot and not the building on it. For a house in Dachsen, the building comes on top, with its age, condition and fit-out. Houses have no median in any of the three years; that too needs its own valuation.

The tariff is the same throughout the canton. Dachsen only levies the tax.¹ It rises in steps. The first CHF 4,000 are taxed at 10 per cent, parts above CHF 100,000 at 40 per cent. Ownership then brings a reduction, 20 per cent in the example after 10 full years.

From 20 full years the reduction is highest, 50 per cent. In the example, CHF 46,500 would then be due instead of CHF 74,400.¹ For a purchase over 20 years ago, the market value of 20 years ago may also count. Documented value-enhancing investments reduce the gain further; maintenance alone does not.

Buy a new home to live in, and the tax can be deferred. You must have lived in the old home yourself and replace it in Switzerland.¹ If the new home costs less than the proceeds, the difference is taxable at once. If it costs no more than the old purchase price and investments, nothing is deferred.⁹ And deferred does not mean waived.
