Selling property in Grüningen: no median, but a notary in the village

The cantonal model puts Grüningen's residential building land at CHF 1,372 per square metre for 2025.⁷ In 2015 it was still CHF 772, a rise of 77.7 per cent in ten years. The range typically runs from CHF 963 to CHF 1,969 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 per square metre between 2021 and 2025.⁷ The two figures are built differently. Grüningen's model value sits around a fifth below it.

For your own plot this value is only a starting point. The model shows a middle value for bare land in the municipality, not the location and shape of your plot. For a house, the building adds age, condition and fit-out on top. Both are derived separately and backed with documents; hearsay prices are no substitute.

Grüningen lies in Hinwil district, and there the number of sales is enough for a median. In 2025, 323 condominiums were sold on the open market in the district, at a median of CHF 950,000.² In 2015, 267 sales gave a median of CHF 696,000. That is a rise of 36 per cent over ten years.

As a price for a flat in Grüningen, this figure does not work. It bundles sales from across the district, from Hinwil as well as from small municipalities. Where exactly the flats sold were located, the statistics do not show.

For houses, the district reports a 2025 median of CHF 1,250,000, from 213 sales.² The cantonal house median was CHF 1,590,000 in 2025, so the Hinwil district median sits 21 per cent below it. What this means for you: the district figure describes the market around Grüningen, not your house. That takes location, plot and building, each valued in its own right.

The property gains tax follows the same tariff everywhere in the canton; Grüningen only levies it.¹ It rises with the gain in steps. The first CHF 4,000 are taxed at 10 per cent, parts above CHF 100,000 at 40 per cent. Ownership then reduces the tax, here 20 per cent after 10 full years.

From 20 full years the reduction reaches its maximum of 50 per cent. From the same gain, only CHF 45,500 would then be due instead of CHF 72,800.¹ Owners of more than 20 years may use the market value of 20 years ago instead. Documented value-enhancing investments reduce the gain further; maintenance does not.

Invest the proceeds in an owner-occupied home in Switzerland, and the tax can be deferred.¹ The home sold must also have been owner-occupied. 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.
