Market data for Altstätten at a glance: purchase prices for houses and flats, rents, and land values, each with a history of several years. The basis is publicly available statistics and analyses from the valuation committees.
For Swiss municipalities, the Federal Statistical Office (FSO) does not publish square metre prices per municipality, but rather the national residential property price index IMPI. We therefore show the national index – as a reference for long-term price development in Altstätten. Basis: Q4 2019 = 100.
Index level 2026: 126.8 points (Basis Q4 2019 = 100)
The national FSO index IMPI reflects the development of transaction prices for owner-occupied housing in Switzerland. As the FSO does not publish square metre prices specific to municipalities, the national index serves as a reliable reference for long-term price development — including in Altstätten.

Altstätten is one of those municipalities where it is not possible to establish a statistically reliable price per square metre because there are too few transactions. Buyers should factor in ancillary costs, any backlog of renovations and energy standards. Especially with older properties, this determines the actual financial burden. The Rheintal district generally serves as a comparison area, as the demand profile and construction style there are most comparable to Altstätten. We continuously update the data for Altstätten and provide a source for every figure instead of estimating values.
Frequently asked questions about buying, selling, financing, and living in Altstätten — concisely answered.
For owners in Altstätten who wish to sell their property and continue to live in it, FREITAG® offers the classic property annuity (Immobilienverrentung) — via usufruct (Nießbrauch), Right of residence, Leaseback or Life annuity. You release the capital tied up in your house or condominium in Altstätten and secure a right of residence registered in the land registry.
The model that is particularly in demand is Usufruct: You remain the economic owner, are in the first rank in the land registry, and can even rent out the property if needed. An owner-occupancy termination is contractually excluded for all four models.
Whether it's care costs, gifts to heirs, or a noticeably higher pension: We will check for owners in Altstätten, free of charge, which model suits their life situation, and obtain offers from selected investors and foundations.
For production halls, office buildings, medical centres (Ärztehäuser), and logistics areas in Altstätten FREITAG® brokers both classic sales and Sale & Lease-Back. Buyers include family offices, real estate funds, and private portfolio holders with a long-term horizon.
The process is discreet: contact is made off-market, without an advertisement and without a sign on the property. Employees, customers and competitors in Altstätten will not know anything, as long as you don't wish it.
It starts with a reliable valuation based on the income approach (Ertragswert) — not a desired figure. Based on this, you decide whether to sell, lease back, or hold.
Hospitality properties in Altstätten are valued differently from residential properties: Key factors are turnover, contribution margin, seating capacity, kitchen technology, licences, and whether the business can function without the previous owner. We value based on the earnings approach and openly state which portions are attributable to the property, inventory, and goodwill.
Marketing is conducted discreetly. A publicly visible sales offer unsettles staff, regular customers, and suppliers in Altstätten — therefore, we approach interested parties specifically and under a confidentiality agreement.
Whether selling, leasing, or handing over to a successor within the family: We structure the path that suits the situation of your business in Altstätten , and accompany you until the notary or lease agreement appointment.
