Home value estimator St. Gallen: get an appraisal of your house or apartment in Eastern Switzerland

The city’s median asking price for condominiums is CHF 7,663 per m². The middle half of the listings ranges from CHF 6,687 to 10,087. Single-family homes have a median of CHF 9,659 per m². Comparis analyzed 192 apartment and 43 house listings from October 2025 to September 2026.

The Centrum district is 6 percent above the city median. The Osten and Westen districts are at the city median. Among the neighborhoods, St. Fiden stands out at CHF 8,774 per m². The reason is a large new-build project. Over half of the listings there are new builds. Bruggen and Notkersegg are at the city median. Langgass-Heiligkreuz and Winkeln are 7 and 11 percent less expensive, respectively. There are too few listings for the other neighborhoods. This comparison uses listings from October 2024 to September 2026.

Mostly, yes. Apartments in Wittenbach, Herisau and Gossau are listed at 13 to 23 percent less. Speicher and Gaiserwald are about the same. In Mörschwil, apartments cost 19 percent more, and in Teufen 13 percent more. Single-family homes in Teufen, however, are 10 percent less expensive than in the city.

At the end of September 2026, comparis.ch listed 71 apartments in St. Gallen. There were also 24 houses for sale. This means apartment supply grew by 58 percent within a year. Across Switzerland, supply fell slightly over the same year, by 1 percent. New builds account for just over a fifth of apartment listings in St. Gallen.

The process starts with the free online estimate from Comparis. All you enter is location, living space, year of construction and features. You receive the estimate as soon as you have confirmed your e-mail address.

Would you like a more precise figure? Then property experts from the Comparis partner network value your property on site. This service is free and non-binding as well.

They check location, condition and features and compare them with listings in the neighborhood. In St. Gallen, the district matters. In the Centrum district, asking prices are 6 percent above the city median.

The land register extract is issued by the St. Gallen city land register office (Grundbuchamt der Stadt St. Gallen). It keeps three land register districts (Grundbuchkreise): St. Gallen, St. Fiden and Bruggen.

You get the Comparis online estimate for free, with no commitment. The on-site valuation by property experts from the Comparis partner network is free too. The Comparis broker service sets it up for you.

An accurate value is worth it. A 4.5-room apartment in St. Gallen has a median asking price of CHF 892,500. Here, a deviation of 2 percent comes to almost CHF 18,000.

• District and neighborhood: The Centrum district is above the city median. In St. Fiden, a new-build project raises the median, while Winkeln is clearly below it.

• New build or existing property: Just over a fifth of apartment listings are new builds. Without them, the median is CHF 7,281 per m².

• Old Town: The Abbey District (Stiftsbezirk) has been a UNESCO World Heritage Site since 1983. Around it, protection rules limit alterations.

• Zoning plan: The city is revising its zoning plan and building regulations. What can be built in the future may change a plot’s value.

• Condition and energy: Heating, insulation and a building energy certificate (GEAK) are part of the valuation.

• Transport: Quick access to the railway station, buses and the S-Bahn influences the price.

• Interest rates: Higher mortgage rates reduce the budget of many potential buyers.

Requesting the online estimate takes you around three minutes. Once you have confirmed your e-mail address, you receive it by e-mail.

There is no fixed duration for the on-site valuation. A heritage-protected Old Town house needs more checks than a newer apartment in Winkeln. If you would like a written appraisal report, it takes longer.

Many appraisers hold the Federal Diploma of Higher Education as real estate appraisers. Many are members of the SIV (Schweizer Immobilienschätzer-Verband) or the SVIT chamber of valuation experts (Bewertungsexperten-Kammer SVIT). Those who work internationally often hold the MRICS title.

Local knowledge also helps in St. Gallen. Between Winkeln and St. Fiden, asking prices differ by around CHF 2,250 per m².

A valuation lets you set an asking price in line with the St. Gallen market.

Banks value the property themselves before granting a mortgage. The guidelines of the Swiss Bankers Association require this.

Profits from a sale are subject to cantonal property gains tax (Grundstückgewinnsteuer). If you have owned the property for less than five years, a surcharge applies. After more than 15 years, the tax decreases.

Did you buy more than 20 years ago? Then the official market value (amtlicher Verkehrswert) from 20 years ago may serve as acquisition cost.

Property transfer tax (Handänderungssteuer) of 1 percent is owed by the buyer. However, the seller is jointly and severally liable.

Spouses and descendants pay no inheritance tax in the canton of St. Gallen. Even so, a valuation supports a fair division of the estate.

• Land register extract: from the St. Gallen city land register office (Grundbuchamt der Stadt St. Gallen)

• Building insurance: policy from the St. Gallen cantonal building insurer (Gebäudeversicherung des Kantons St. Gallen, GVA) with the insured value

• Plans: floor plans with floor areas and a site plan showing plot boundaries

• Building permits: for alterations and extensions

• Energy: building energy certificate (GEAK), if available

• Condominiums: regulations, meeting minutes and the balance of the renovation fund

• Rented properties: lease agreements and rent roll

• Earlier documents: purchase contract and previous valuations

With complete documents, the valuation becomes more accurate.
