ProofPrice

What did homes sell for in Altstetten?

Home sale prices in Switzerland, from Statistik Stadt Zürich. This source is answered live, so the page shows how to ask, not a number.

Prices recorded in official records of completed sales. Asking prices are never used.

ProofPrice reads Statistik Stadt Zürich when you ask, so the answer is always the latest published. It comes with its period, its source and its licence; a range built from records is given only when at least 5 records sit behind it.

Where this comes from

Source
Median price of freehold condominiums sold, by year and city district (Statistik Stadt Zürich), published by Statistik Stadt Zürich (Präsidialdepartement der Stadt Zürich)
Licence
Creative Commons CCZero (CC0 1.0): the dataset's licence on data.stadt-zuerich.ch.
Attribution
Source: Statistik Stadt Zürich, Open Data Zürich, 'Preise für Stockwerkeigentum nach Stadtquartier' (data.stadt-zuerich.ch, CC0 1.0).
How fresh the source is
Yearly; the latest year published is 2025 (dataset updated 8 Jan 2026). Each answer states its year.
Limits
Freehold condominiums sold between private parties in the city of Zürich only, not houses, inheritances, gifts or sales between related parties, and not the rest of Switzerland. One median per area and year: no 10th-90th percentile range is published. Areas with fewer than 5 sales in a year, or where the publisher shows a range or 'K' instead of a number, are not answered. Yearly, so up to a year behind.
Rule
A figure built from records is shown only when at least 5 records sit behind it; official statistics are shown as such, with their reference period. See how we earn trust and the method.
