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. 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.

Pricing in Au works on a property-specific basis. Condition, plot, orientation, and development explain more than any regional average. An asking price that is too high results in a measurable loss of time in Au. Properties that remain on the market for a long time are systematically negotiated below value by prospective buyers later on. The Rheintal district generally serves as a comparison area, as the demand profile and construction methods there are most comparable to Au. An individual valuation for a specific property in Au is possible despite the sparse data situation; it is carried out using comparative values and a property inspection.
Frequently asked questions about buying, selling, financing, and living in Au — concisely answered.
Many owners in Au 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 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 many businesses, capital is tied up in Au in their own property instead of in operational business. Sale & Lease-Back solves this: sale to an investor, simultaneously a long-term lease agreement that secures usage. Business operations, address, and workforce remain where they are.
A lot changes in the balance sheet — the property leaves the fixed assets, depreciation becomes rental expense. Whether this is advantageous for your company depends on the legal form, financing structure, and tax starting position; therefore, we calculate this together with your tax advisor before anything is signed.
Crucial for the achievable price are the lease agreement term, creditworthiness, and third-party usability (Drittverwendungsfähigkeit) of the property in Au. We structure these points so that the sales proceeds and the subsequent rental burden are in a reasonable relationship.
Hospitality properties in Au 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 — 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 , and accompany you until the notary or lease agreement appointment.

From measurements and the energy performance certificate to buyer selection: We fully prepare your house before it goes on the market — and conduct negotiations up to notarisation.
We consider the declaration of division (Teilungserklärung), service charge (Hausgeld), energy performance certificate, reserves, and target group — and structure the entire sales process for you.
We clarify the development plan, development status, and suspected contamination in advance — this prevents price reductions during negotiations.
Third-party usability, remaining term of rental agreements, and tenant creditworthiness determine the price of your commercial property. We tailor the documents precisely to these factors.

Professional market placement, well-considered tenant selection, and legally sound documents for a smooth letting of your flat.
From defining the ancillary costs arrangement to the handover: We structure the letting of your house in such a way that no disputes arise later.
Right of residence (Wohnrecht), leaseback, life annuity (Leibrente), or usufruct (Nießbrauch) — we examine the most suitable option for you and advise on opportunities and framework conditions.
Comparative value, intrinsic value (Sachwert) or income approach (Ertragswert): We select the appropriate method for the property and disclose the derivation, instead of just stating a number.
