Below you will find a clear presentation of current purchase prices, rents, and land values in Altnau. The data is based on publicly available statistics and valuation committee analyses — as a basis for decision-making for owners, buyers, and investors.
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 Altnau. 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 Altnau.

We do not have any officially reliable transaction series for Altnau. A valuation is therefore based on comparable properties in the surrounding municipalities. Capital investors should check the re-letting potential in Altnau. In small municipalities, the pool of tenants is limited, but tenancies are often long-term. The district of Kreuzlingen generally serves as the comparison area, as the demand profile and construction style there are most comparable to Altnau. We continuously update the information on Altnau and cite the source for every figure, rather than estimating values.
Frequently asked questions about buying, selling, financing, and living in Altnau — concisely answered.
Property annuity (Immobilienverrentung) in Altnau means: You transfer ownership, but retain the right of use. Four options are available — Usufruct (Nießbrauch) (most extensive rights, including letting), Right of abode (personal use), Life annuity (monthly payment instead of a lump sum) and Sale-and-leaseback (sale at full price, followed by a rental agreement).
Which option is suitable depends on your age, health status, inheritance situation and the current market value of your property in Altnau. These factors directly influence the valuation — therefore, we do not make blanket promises regarding the achievable amount.
The initial consultation is free and without obligation. Upon request, we will involve relatives, tax advisors or notaries from the outset, so that the solution is also sustainable within the family in Altnau.
For many businesses, capital is tied up in Altnau 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 Altnau. We structure these points so that the sales proceeds and the subsequent rental burden are in a reasonable relationship.
Hospitality properties in Altnau 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 Altnau — 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 Altnau , and accompany you until the notary or lease agreement appointment.

Altnau is located in a border region — many of our clients compare locations across countries. These municipalities in neighbouring countries offer similar location qualities and are often the closest alternative:
Detailed analysis of the plot, year of construction, condition, and micro-location. We develop an individual marketing strategy and support the house sale up to the notary appointment.
Whether rented or vacant: We assess which buyer group is realistic for your flat, and consistently align the exposé, price, and approach accordingly.
Developability, layout, development status, and land value guide are crucial. We provide a realistic valuation and specifically address suitable buyers and investors.
Valuation based on the income approach (Ertragswert), review of rental agreements, and targeted approach to portfolio holders and family offices — without public advertising.
The right rental price determines whether a property stands vacant or has long-term tenants. We set it at a market-appropriate level and pre-filter interested parties, instead of holding mass viewings.
Detached houses, semi-detached houses, or terraced houses appeal to different target groups — we ensure the appropriate presentation and solvent tenants.
We calculate how much a registered right of residence (Wohnrecht) reduces the purchase price — and whether property annuity (Immobilienverrentung) is worthwhile for you compared to a traditional sale.
For inheritance disputes, divorce, banks or sales — a reliable valuation that stands up to scrutiny from third parties.
Contact us — we will advise you without obligation on valuation, marketing, and next steps.
