The following figures show how purchase prices, rents, and land values have developed in Gränichen. 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 Gränichen. 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 Gränichen.

In Gränichen, the supply is limited. Those who buy here often choose a property for long-term personal use, rather than as a short-term investment. Buyers should take into account additional costs, maintenance backlogs, and energy standards. Especially with older properties, these factors determine the actual financial burden. The district of Aarau generally serves as the comparative area, as the demand profile and construction style there are most comparable to Gränichen. For reasons of transparency, we do not provide price per square metre figures for Gränichen as long as there is no reliable data basis.
Frequently asked questions about buying, selling, financing, and living in Gränichen — concisely answered.
Many owners in Gränichen 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 Gränichen 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 Gränichen 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 Gränichen 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.
Whether a country inn, city café, hotel garni, or boarding house with an annex — for hospitality and accommodation properties in Gränichen 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 Gränichen 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 Gränichen legally permissible under building law, we clarify before marketing.

The "Unterfeld" residential development with three apartment buildings is being built on the outskirts of Gränichen. Rental and owner-occupied apartments are planned; the move-in date was stated as autumn 2023.
Gränichen closed the 2024 annual financial statement with a surplus of over 1.3 million Swiss francs. The main reason was significantly higher tax revenues; at the same time, the investment budget showed net investments of around 1.9 million Swiss francs.
Several projects are planned in the village center of Gränichen, including two apartment buildings, a new church building, a workshop, and the conversion of the protected Stöckli house. The construction costs for the projects are estimated at a total of around 13 million Swiss francs.
The groundbreaking ceremony for the "Farnweg" project in Gränichen has taken place. 16 terrace apartments and one apartment building with five owner-occupied apartments are planned; move-in is scheduled from autumn 2026.
The municipality of Gränichen achieved a surplus of 202,369 Swiss francs in 2023. The municipality also remained a recipient municipality in the Aargau financial equalization scheme, with corresponding payments also for 2025.
