Without official prices
What is a house in Kaltbrunn worth without official price statistics?
Anyone selling in Kaltbrunn will find no official price figure. The Canton of St. Gallen keeps no median prices by municipality; the Canton of Zurich does. Listing figures for Kaltbrunn show what is asked, not what was paid.
What is on record is the stock: Kaltbrunn has 1,082 buildings with residential use in the See-Gaster constituency. 554 of them are single-family houses, or 51.2%. The cantonal figure is 59.2%. Kaltbrunn ranks 9 of 10 in the See-Gaster constituency. In total, Kaltbrunn has 2,383 dwellings. 42.8% were built before 1981, against 58.9% in the canton. 11.5 hectares of 124 hectares of building zone are undeveloped, or 9.3% (as of 2022). For the share of undeveloped zone, Kaltbrunn ranks 9 of 75 in the canton.

Current in Kaltbrunn
Which new plans have applied in Kaltbrunn since October 2026?
On 31 October 2025, the cantonal civil engineering office approved the full revision of the municipal road plan.14 It includes a partial plan for footpaths, hiking trails and cycle paths.14 A single road classification was appealed. On 13 August 2026, the cantonal Department of Building and Environment granted the municipality partial legal force.14 The undisputed parts have been in force since 1 October 2026.14
On the same day, the special-use plan «Festlegung Gewässerraum Dorfbach Nord» also took effect.15 The cantonal Office for Spatial Development and Geoinformation approved it without restrictions on 29 June 2026.15 No appeal was lodged in time against the council decisions of 10 August 2026.15
For landowners along the Dorfbach, the plan sets the watercourse space in binding form. This space is reserved for the stream, and new buildings are only allowed there to a limited extent. Anyone selling there should have the boundary checked with the building office first. That avoids surprises once buyers draw up their own building plans.

Selling in the Canton of St. Gallen
What applies when selling in the Canton of St. Gallen: tax, land registry, notarisation?
The canton taxes the gain on sale, price minus costs, on a progressive scale.2 After more than 15 years of ownership, the tax falls yearly, by up to 40.5% if you lived there 15 years or more.2 This applies to the gain up to CHF 500,000; otherwise the cap is 20%.2 Within 5 years, the tax rises.2
Selling a home you lived in permanently and exclusively can defer all or part of the tax.3 You buy a similarly used home in Switzerland from 1 year before to 3 years after the sale.4 Deferred does not mean waived.3
The buyer owes a 1% transfer tax (Handänderungssteuer) on the price.5 The seller is jointly liable; between parents and children, half the rate applies.5
The municipal land registry where the property lies notarises the sale contract.6 The registry fee is 0.2% up to CHF 2 million, 0.05% above.7 If the land registry also notarises the contract, the fee doubles.7
