Selling property in Schlatt: no flat sold in 2015 or 2025

The first point of reference is building land. For Schlatt, the cantonal model puts residential building land at CHF 560 per square metre for 2025.⁷ For 2015 the model gave CHF 380; the 2025 figure is up 47.4 per cent. Its typical range in Schlatt is CHF 394 to CHF 792.

Across the whole canton, residential building land sold at a median of CHF 1,742 per square metre in 2021 to 2025.⁷ That is a median of prices actually paid, whereas the Schlatt figure is an estimate. So the comparison only shows the order of magnitude: Schlatt is clearly lower.

For your own plot the model is no substitute for a valuation, because it only describes undeveloped land. If a house stands on it, the building comes on top, with its age, condition and fit-out. The canton shows no official house price per square metre of land for Schlatt in any reference year. Your figure therefore comes from location, plot and building, backed by documents.

First of all, only what the statistics count: open-market sales in three reference years. For condominiums that was two in 2007 and none in 2015 or 2025.² The years in between are not analysed here. For these two years, a flat owner in Schlatt thus has no comparable sale from the village.

The next official yardstick is Winterthur district. There the flat median stood at CHF 950,000 in 2025, counted from 536 sales.² In 2015 it had been CHF 695,000, counted from 413 sales. By 2025 it had therefore risen by 37 per cent.

This figure mixes sales from across the district, the city of Winterthur included. For a flat in Schlatt it describes the surroundings, not its price. The same goes for houses: in 2025 the district showed a house median of CHF 1,330,000, from 309 sales. That figure, too, does not replace a look at your own property.

Schlatt only collects the tax; the canton sets the tariff.¹ The rate climbs from 10 per cent on the first CHF 4,000 of gain to 40 per cent above CHF 100,000. The example comes to CHF 91,400 before the holding period counts.

After 10 full years the tax falls by 20 per cent, after 15 by 35 per cent. With 20 full years the cut is 50 per cent: the same gain would then cost CHF 45,700, not CHF 73,120. Bought over 20 years ago? The market value of 20 years ago may replace the purchase price. Documented value-enhancing investments reduce the gain; plain maintenance does not.

Buying a new home can defer the tax. You must have lived in the old home yourself and live in the new one, in Switzerland.¹ If it costs less than the proceeds, the difference is taxable at once. If it costs no more than the old purchase price plus investments, nothing is deferred.⁹ Deferred does not mean waived.
