Market data for Au SG 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 Au SG. 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 Au SG.

We do not have any officially reliable transaction series for Au SG. A valuation is therefore based on comparable properties in the surrounding municipalities. An initial price that is too high measurably costs time in Au SG. Properties that remain on the market for a long time are later systematically negotiated below value by prospective buyers. The Rheintal district generally serves as a comparison area because the demand profile and construction style there are most comparable to Au SG. An individual assessment for a specific property in Au SG is possible despite the thin data situation; it is carried out using comparative values and a property inspection.
Frequently asked questions about buying, selling, financing, and living in Au SG — concisely answered.
Many owners in Au SG are sitting on an asset that they cannot access because they do not want to give up their home. This is precisely whatProperty annuity (Immobilienverrentung) is for: The sale takes place, but the move-out does not. Depending on the model — Usufruct, Right of abode, Life annuity or Leaseback — the purchase price is paid as a lump sum, as a monthly annuity, or as a combination of both.
Security is crucial: The right of abode (Wohnrecht) is entered in the land register (Grundbuch) in the first rank, before the buyer is registered as the owner. We will calculate for your property in Au SG how much the usufruct (Nießbrauch) value reduces the purchase price — and whether this is more profitable compared to a traditional sale.
We approach this with an open mind. If a normal sale with a subsequent move is economically better for you, we will tell you — instead of trying to sell a property annuity (Immobilienverrentung) model that doesn't suit your needs.
For production halls, office buildings, medical centres (Ärztehäuser), and logistics areas in Au SG 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 Au SG 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 Au SG 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 Au SG — 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 Au SG , and accompany you until the notary or lease agreement appointment.
