A Swiss property sale typically takes 3–6 months from preparation to the land-register entry; in sought-after locations such as the city of Zurich, on Lake Zurich, in Geneva or ZG, 2–3 months is realistic, and for exceptional properties 6–12 months. The customary agent's commission is 2–3% of the sale price (1.5–2% for apartment buildings or high-priced properties), with total sale costs incl. taxes and notary at 3–5%. The purchase of real estate requires public notarisation without exception (Art. 216 OR / Art. 657 ZGB). This guide walks you through all seven phases of the sale.
In Swiss market practice, the seller almost always bears the commission of 2–3% of the sale price (1.5–2% for apartment buildings or yield properties). On CHF 1.2 million, that is CHF 24'000–36'000. It is deducted from the sale proceeds and is deductible as a sale expense for property gains tax (Grundstückgewinnsteuer). Passing it on to the buyer is atypical and would have to be explicitly agreed. Under Art. 417 OR, an excessively high broker's fee (Mäklerlohn) can be reduced by the judge on application — for commissions over 5%, regularly reduced.
Property gains tax (Grundstückgewinnsteuer) is levied on the difference between the sale price and (acquisition price + value-enhancing investments + sale costs). It is cantonal/communal and progressive: in the Canton of Zürich between 10% (small gains) and 40% (high gains over CHF 100'000). On top of this, a 50% surcharge for a holding period under 1 year, 25% for 1–2 years — conversely, a reduction of 3% per year from the 5th holding year, up to a maximum of 50%. In the case of a replacement purchase (Ersatzbeschaffung), a tax deferral can be claimed.
Complete documents sell 20–40% faster. Mandatory are: a current land-register extract (max. 3 months old), the cadastral plan, floor plans, the building permit (where available), the register of easements, and for condominium ownership the bylaws, the deed of constitution, the last 3 sets of minutes plus the renewal-fund balance. Added to this is the GEAK/energy certificate in cantons with a GEAK requirement. If documents are missing, the financing bank pulls out and the sale is delayed by weeks.
Define three prices and communicate only the first: the asking price (listing price), typically 3–5% above the target price as room for negotiation; the target price as the realistically expected close after 4–8 weeks of marketing; and the walk-away limit as a rule of thumb 5–8% below the target price. Valuation methods range from the hedonic online valuation (± 10–15%, CHF 0–100) to a market-value appraisal (Verkehrswert) (± 3–7%, CHF 1'500–4'500). The set-high-and-negotiate-down strategy is statistically the worst approach.
Self-marketing costs only platform fees of CHF 200–800 plus self-procured photos/notary, but ties up the seller for 40–80 hours over 3–6 months and, with weak marketing, statistically achieves on average 2–5% lower prices. The agent costs 2–3% commission but brings a buyer pool and negotiation leadership. Professional photos are the biggest lever: listings with them are clicked 5–10× more often; an investment of CHF 400–1'500 for a property photographer.
The transaction is completed before a Notar (OR Art. 216 / ZGB Art. 657). In addition to the Grundstückgewinnsteuer (paid by the seller, 10–40 % of the gain), the Handänderungssteuer applies: 0–3 % of the sale price, abolished in the Canton of Zurich (ZH) since 2005 (0 %), as well as in Schwyz (SZ) and Schaffhausen (SH); Bern (BE) levies around 1.8 %. Notar fees amount to 0.1–0.5 %, Grundbuch fees to 0.1–0.3 %. If the broker is liable for MWST, 8.1 % MWST is added to the Maklerprovision. A down payment belongs exclusively in a notarial Treuhandkonto.
