CHF. «–»: fewer than 15 sales, so no official median. Sources: Office for Statistics and Data, Canton of Zurich (KTZH_00000077, KTZH_00003158, tax rates 2026, KTZH_00000254); 2023–2025 values provisional.
Where is building land most expensive on the Zimmerberg?
The canton's model puts residential building land highest in Rüschlikon: CHF 6,690 per square metre. Kilchberg follows with CHF 5,077 and Oberrieden with CHF 3,293.2 At the other end is Wädenswil at CHF 1,558.
The pace differs too. Over ten years, the model value rose most in Rüschlikon, by 176.8 percent. The model estimates land value from the sales of recent years. It is recalculated retroactively every year. The most expensive municipality is thus 4.3 times the cheapest.
What this means for you: with an older house, the land often makes up most of the value. A regional average can therefore be far off. What counts is your plot, its zone and what may be built on it. Unused building potential can raise the land value further. More in the building land price guide.
How much does tax differ on the Zimmerberg?
On the gain from the sale, not at all. Property gains tax follows the same tariff throughout the canton.5 It falls with the holding period: by 5 percent after five full years, by half after 20 full years. You can check your figure in the calculator for the Canton of Zurich.
Income and wealth are different. Here the tax rate of the municipality where you live after the sale applies. On the Zimmerberg, it ranges from 167 percent in Kilchberg to 201 percent in Langnau am Albis.3 Everywhere, 95 percent of this is the cantonal rate; the municipality sets the rest.
On the same income, you therefore pay around 20 percent more cantonal and municipal tax in Langnau am Albis than in Kilchberg, excluding church tax. What this means for you: if you sell and move within the region, include your new place of residence. This matters most for pensions, investment income and larger assets.
Who is selling on the Zimmerberg?
The 9 municipalities are home to 133,157 people, 26,181 of them aged 65 or over. That is 19.7 percent, against 17.7 percent across the canton.4 The highest share is in Oberrieden at 24.4 percent. In 4 of the 9 municipalities, at least one person in five is 65 or over.
Many houses change hands after a turning point in life: after an inheritance, when moving into a flat or when care comes closer. Each of these situations raises its own questions about tax, deadlines and family. Planning early lets you align the sale, the move and the tax calmly. The net proceeds calculator shows what remains after the sale.
What this means for you: before selling, clarify who has a say and which deadlines apply. In a community of heirs, all heirs must agree to the sale. The home check gives an overview of your situation.

What else do owners on the Zimmerberg ask?
Do you handle sales in all municipalities on the Zimmerberg?
Yes. I support sales throughout the Canton of Zurich, on the Zimmerberg, for example in Kilchberg, Thalwil, Horgen and Wädenswil. The valuation with a net calculation is free and without obligation.
Where do the prices on this page come from?
From the open-market sales analysed by the Office for Statistics and Data of the Canton of Zurich. A median is only published from 15 sales per year. The values for 2023 to 2025 are provisional.
Why is there no house price for some municipalities?
Because fewer than 15 detached houses were sold on the open market there in 2025. On the Zimmerberg, this applies to 4 of 9 municipalities. The value can then only be derived from the property itself, with comparisons from the area and the land value.
Is the median price the value of my house?
No. The median is the middle price of all sales in a year. Location, plot, condition and zone often move the value of an individual house considerably up or down.
Your municipality on the Zimmerberg, your house, your figure: I set out in writing what remains after tax and costs.
