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

Pricing in Islisberg works on a property-specific basis. Condition, plot, orientation and development explain more than any regional average. Buyers should factor in additional costs, renovation backlog and energy standards. Especially with older properties, this determines the actual financial burden. The district of Bremgarten generally serves as a comparison area, as the demand profile and construction style there are most comparable to Islisberg. As soon as reliable market data for Islisberg is available, we will add it here, including the source and date.
Frequently asked questions about buying, selling, financing, and living in Islisberg — concisely answered.
Many owners in Islisberg 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 Islisberg 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 Islisberg 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 Islisberg 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 Islisberg 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 Islisberg 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 Islisberg legally permissible under building law, we clarify before marketing.

Islisberg 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.
We consider the declaration of division (Teilungserklärung), service charge (Hausgeld), energy performance certificate, reserves, and target group — and structure the entire sales process for you.
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.
Right of residence (Wohnrecht), leaseback, life annuity (Leibrente), or usufruct (Nießbrauch) — we examine the most suitable option for you and advise on opportunities and framework conditions.
Understandable valuation as a basis for sale or letting — carried out by certified experts with regional market knowledge.
