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

Onex is one of the municipalities where no statistically reliable price per square metre can be established because too few transactions take place. Buyers should factor in additional costs, maintenance backlogs, and energy standards. Especially with older properties, this determines the actual financial burden. As soon as reliable market data for Onex becomes available, we will add it here, including the source and date.
Frequently asked questions about buying, selling, financing, and living in Onex — concisely answered.
Property annuity (Immobilienverrentung) in Onex 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 Onex. 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 Onex.
For production halls, office buildings, medical centres (Ärztehäuser), and logistics areas in Onex 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 Onex 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 Onex 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 Onex 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 Onex legally permissible under building law, we clarify before marketing.
