Selling property in Trüllikon: no median, nearly a quarter 65 or over

None for houses and flats, but one for building land. In the cantonal model, residential building land in Trüllikon stands at CHF 570 per square metre for 2025.⁷ In 2015 the model still showed CHF 425, so the value is up 34.1 per cent. Its typical span reaches from CHF 397 to CHF 805.

The canton also reports what was actually paid for residential building land. Pooled across the whole canton, the median for 2021 to 2025 was CHF 1,742 per square metre.⁷ That is a different measure from the model value of a single municipality. The two figures therefore cannot be set directly against each other.

For your house, the model value is only the start. It applies to undeveloped land, not to your specific plot with its location and shape. The building comes on top, with its age, condition and fit-out. Both are derived separately and backed up with plans, receipts and comparable properties.

As far as a median of many sales can go. In Andelfingen district, 129 flats were sold on the open market in 2025, at a median of CHF 900,000.² Ten years earlier, 100 sales gave a median of CHF 641,000. Within ten years the district median thus gained 40 per cent.

For houses, 143 sales in the district produced a 2025 median of CHF 1,273,600.² Both district medians are below the cantonal medians of CHF 1,200,000 for flats and CHF 1,590,000 for houses. The gap is about 25 per cent for flats and about 20 per cent for houses.

These figures combine sales from across the whole district. Which properties were sold where, the statistics do not show. For Trüllikon they are therefore a frame, not a price. The worked example uses the flat median only to make the tax tangible. It is no measure of a house's value.

A great deal. The tariff is the same throughout the canton, but the reduction depends on how long you have owned it.¹ From five full years it is 5 per cent, then 3 percentage points are added each year. After 20 full years the maximum of 50 per cent is reached. In the worked example, the tax would fall from CHF 74,400 to CHF 46,500.

Purchased more than 20 years ago? Then the market value of 20 years ago may replace the old purchase price.¹ Documented value-enhancing investments reduce the gain; mere maintenance does not. Old invoices and plans therefore matter.

If the proceeds go into a new home in Switzerland that you live in, the tax can be deferred. You must also have lived in the old one yourself.¹ If the new home costs less than the proceeds, the difference is taxable at once. Where it costs no more than the old purchase price plus investments, there is no deferral at all.⁹ Deferred does not mean waived.
