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 Untersiggenthal. 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.

An initial price that is too high measurably costs time in Untersiggenthal. Properties that remain on the market for a long time are systematically negotiated below their value by prospective buyers later on. The market in Untersiggenthal is tight. Supply and demand often meet through personal contacts before a property is even publicly advertised. The district of Baden generally serves as a comparison area, as the demand profile and construction style there are most comparable to Untersiggenthal. An individual assessment for a specific property in Untersiggenthal is possible despite the thin data situation; it is carried out using comparative values and a property inspection.
Frequently asked questions about buying, selling, financing, and living in Untersiggenthal — concisely answered.
Many owners in Untersiggenthal 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 Untersiggenthal 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 many businesses, capital is tied up in Untersiggenthal in their own property instead of in operational business. Sale & Lease-Back solves this: sale to an investor, simultaneously a long-term lease agreement that secures usage. Business operations, address, and workforce remain where they are.
A lot changes in the balance sheet — the property leaves the fixed assets, depreciation becomes rental expense. Whether this is advantageous for your company depends on the legal form, financing structure, and tax starting position; therefore, we calculate this together with your tax advisor before anything is signed.
Crucial for the achievable price are the lease agreement term, creditworthiness, and third-party usability (Drittverwendungsfähigkeit) of the property in Untersiggenthal. We structure these points so that the sales proceeds and the subsequent rental burden are in a reasonable relationship.
Whether a country inn, city café, hotel garni, or boarding house with an annex — for hospitality and accommodation properties in Untersiggenthal 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 Untersiggenthal 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 Untersiggenthal legally permissible under building law, we clarify before marketing.

Are you looking for a real estate agent not directly in Untersiggenthal, but in the surrounding area? FREITAG® also serves the following municipalities in Aargau with local market knowledge, current purchase prices, and personal advice:
Untersiggenthal 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.
Developability, layout, development status, and land value guide are crucial. We provide a realistic valuation and specifically address suitable buyers and investors.
Office, practice, warehouse, hotel, or gastronomy — discreet marketing with a sound valuation and personal support until completion.
Credit checks, self-disclosure forms, handover protocols, and a clear tenancy agreement — we handle the entire letting process, including viewings.
For houses, tenant quality matters more than the final price point. We select tenants who will look after the property long-term.
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.
For inheritance disputes, divorce, banks or sales — a reliable valuation that stands up to scrutiny from third parties.
Contact us — we will advise you without obligation on valuation, marketing, and next steps.
