Selling property in Aesch: from 28 minutes to Zürich, but no median

In Aesch the derivation starts with the land. The cantonal model puts residential building land in Aesch at CHF 1,895 per square metre for 2025.⁷ In 2015 it was still CHF 1,178, a rise of 60.9 per cent in ten years. Typically the model ranges from CHF 1,325 to CHF 2,715 per square metre. Among the 160 municipalities in the canton, the model rates land higher in 54 and lower in 105.

For the canton as a whole there is also a median of prices paid. Residential building land fetched a median of CHF 1,742 in 2021 to 2025.⁷ It arises differently from the model; both only serve as rough orientation. The model value of Aesch sits slightly above it.

The model only estimates undeveloped land, not your own plot and not the building on it. For a house in Aesch, the building comes on top, with its age, condition and fit-out. Nor is the district figure a substitute for that derivation.

Aesch belongs to the district of Dietikon. There, sales are enough for an official figure. In 2025 a flat there cost a median of CHF 1,313,000, from 316 sales, a rise of 51 per cent since 2015.² In 2015 the district flat median was CHF 869,000, from 285 sales. Aesch itself only reached 9 flat sales and 2 house sales, both well below the threshold of 15.

In the cantonal statistics, Aesch belongs to the property market region Agglomeration, not to the region Land, and to the planning region Limmattal.⁷ From the stop Aesch ZH, Heligenmattstrasse, you reach Zürich HB from 28 minutes.⁵

A district figure is not a price for a flat in Aesch itself, though. It mixes sales from across the district, from Dietikon to smaller municipalities such as Aesch. What your house or flat is worth only shows in a derivation from location, plot and building.

The tariff is the same throughout the canton; Aesch only levies it.¹ It rises in steps with the gain: 10 per cent on the first CHF 4,000, 40 per cent on the part above CHF 100,000. 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 then be due instead of CHF 133,600.¹ Documented value-enhancing investments reduce the gain further; mere maintenance does not.

Buy a new home to live in afterwards, and the tax can be deferred. You must have lived in the old home yourself and replace it in Switzerland.⁹ 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.
