Market data for Diessenhofen 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 Diessenhofen. 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 Diessenhofen.

We do not have access to officially reliable transaction series for Diessenhofen. Valuations are therefore based on comparable properties in the surrounding municipalities. Capital investors should assess the re-letting potential in Diessenhofen. In small municipalities, the pool of tenants is limited, but rental agreements are often long-term. The district of Frauenfeld generally serves as the comparison area, as the demand profile and construction style there are most comparable to Diessenhofen. We continuously update the data for Diessenhofen and provide the source for every figure rather than estimating values.
Frequently asked questions about buying, selling, financing, and living in Diessenhofen — concisely answered.
Property annuity (Immobilienverrentung) in Diessenhofen 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 Diessenhofen. 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 Diessenhofen.
Entrepreneurs in Diessenhofen who wish to sell their commercial property and lease it back use Sale & Lease-Back: They sell office buildings, warehouses or practice premises to an investor, receive liquidity for growth or consolidation, and lease the property back long-term. The location in Diessenhofen remains unchanged.
FREITAG® accompanies the entire process: value-based valuation, selection of qualified investors, contract drafting with clear lease-back conditions — including options for repurchase and flexible terms.
We check free of charge whether your commercial property in Diessenhofen is suitable for a Sale & Lease-Back and obtain transparent offers — without obligation and without hidden costs.
Hospitality properties in Diessenhofen 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 Diessenhofen — 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 Diessenhofen , and accompany you until the notary or lease agreement appointment.

Visit websiteAre you looking for a real estate agent not directly in Diessenhofen, but in the surrounding area? FREITAG® also serves the following municipalities in Thurgau with local market knowledge, current purchase prices, and personal advice:
Diessenhofen 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:
Plot layout, building fabric, maintenance backlog, and neighbourhood determine the price. We objectively assess these points and align the marketing accordingly.
Minutes of the owners' meeting, maintenance reserve fund, and special rights of use are also decisive for the price. We review the documents before the first viewing appointment.
We clarify the development plan, development status, and suspected contamination in advance — this prevents price reductions during negotiations.
Valuation based on the income approach (Ertragswert), review of rental agreements, and targeted approach to portfolio holders and family offices — without public advertising.
Professional market placement, well-considered tenant selection, and legally sound documents for a smooth letting of your flat.
For houses, tenant quality matters more than the final price point. We select tenants who will look after the property long-term.
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.
Understandable valuation as a basis for sale or letting — carried out by certified experts with regional market knowledge.
Contact us — we will advise you without obligation on valuation, marketing, and next steps.
