Selling property in Oetwil an der Limmat: a median, but no trend

In 2025, 16 condominiums changed hands in Oetwil an der Limmat. That is one more than the cantonal threshold of 15. For 2025, the statistics therefore show a median of their own: CHF 1,410,000.² In 2015 only 14 flats sold, and in 2007 just 8 – both times too few for an official figure.

A single reference year with a median is not a trend, though. Without a second value, there is no way to tell whether the median in the village rose faster or slower than in the district. The ten-year trend therefore comes from Dietikon district, with sales from across the district. There, a flat traded at a 2025 median of CHF 1,313,000, against CHF 869,000 in 2015.²

What this means for you is simple. The 2025 figure shows where the 16 flats of that year traded at the median. A calculation with a 2015 purchase date still needs the district figure, or, better, your own records.

Houses have no median in Oetwil an der Limmat in any of the three years: 8 sold in 2025, 7 in 2015, 5 in 2007 – always below the threshold of 15.²

Land offers a first anchor. The cantonal model puts residential building land at CHF 1,668 per square metre for 2025.⁷ In 2015 it was still CHF 1,085, a rise of 53.7 per cent in ten years. Typically the model ranges from CHF 1,148 to CHF 2,405 per square metre.

For the canton there is a second measure. Residential building land actually sold for a median of CHF 1,742 between 2021 and 2025.⁷ Between 2011 and 2015 it was CHF 800. Model value and sale price are produced differently and only offer a rough sense of scale.

The model only estimates undeveloped land, not your own plot and not the building on it. For a house here, the building comes on top, with its age, condition and fit-out.

The tariff is the same throughout the canton; Oetwil an der Limmat only levies it.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 83,500 would be due instead of CHF 133,600.¹ 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 does not.

If you then buy a new home to live in, the tax can be deferred.¹ You must have lived in the old home yourself and replace it in Switzerland. 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 Deferred does not mean waived.
