The following figures show how purchase prices, rents, and land values have developed in Diepoldsau. These are average values for the entire location — the location, year of construction, and condition of a specific property can deviate significantly from these.
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 Diepoldsau. 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 Diepoldsau.

The real estate market in Diepoldsau is a small sub-market. Few properties come onto the market each year, and consequently, each individual listing has a strong impact on price trends. Buyers should factor in ancillary costs, any backlog of renovation work, and energy standards. Especially with older properties, this determines the actual financial burden. The Rheintal district generally serves as a reference area, as the demand profile and construction style there are most comparable to Diepoldsau. We continuously update the data for Diepoldsau and cite the source for every figure, rather than estimating values.
Frequently asked questions about buying, selling, financing, and living in Diepoldsau — concisely answered.
For owners in Diepoldsau 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 Diepoldsau 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 Diepoldsau, free of charge, which model suits their life situation, and obtain offers from selected investors and foundations.
Entrepreneurs in Diepoldsau 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 Diepoldsau 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 Diepoldsau is suitable for a Sale & Lease-Back and obtain transparent offers — without obligation and without hidden costs.
Whether a country inn, city café, hotel garni, or boarding house with an annex — for hospitality and accommodation properties in Diepoldsau there is a specific, manageable circle of buyers. We have known and cultivated this circle for years, instead of advertising widely.
Often, leasing is the calmer path: you retain the property in Diepoldsau your portfolio, hand over operational management, and receive ongoing income. We check the concept and creditworthiness of the tenant before the contract is concluded.
If the property is vacant or no longer profitable to operate, we examine repurposing — for example, into residential space, a boarding house, or practice premises. What is Diepoldsau legally permissible under building law, we clarify before marketing.

Diepoldsau 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.
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.
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.
Sell and stay living in your home: We compare the four common models based on your situation and clearly state the disadvantages as well as the advantages.
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.
Contact us — we will advise you without obligation on valuation, marketing, and next steps.
