Off-market property in Collonge-Bellerive

Off-market means selling a property without any public listing, through direct introductions to qualified buyers under confidentiality. On the left bank of Lake Geneva, between Vésenaz and the lakeside lanes, this is how the finest addresses are sold.

From Vésenaz to the tip of Bellerive, the municipality offers the most sought-after features of the left bank: waterfront properties on the chemin de Ruth, the villas of Les Marèches, and Geneva right next door. A deep, active market — whose top end never appears on the portals.

Sources: RealAdvisor, median prices per m², readings from August–September 2026. Indicative figures — every property deserves an individual valuation.

One of the strongest rises on the left bank over ten years (+33.5 % for apartments). Prices can double between the heart of Vésenaz and the lakeside lanes — the micro-location sets the price.

Why sell off-market in Collonge-Bellerive

The top of the Collonge-Bellerive market — lakeside properties, large plots on the chemin de Ruth or the chemin des Princes — does not go through listings: the properties are too easy to identify, the sellers too well known. Discreet competition between a few qualified buyers from the network protects both the price and confidentiality.

Before selling, estimate the Geneva property gains tax (IBGI) with our simulator (in French), which takes the holding period into account.

The OFFER process: a confidential valuation within 72 hours based on real transactions in the sector, a shortlist of three to five qualified buyers under a non-disclosure agreement, discreet viewings, a controlled competitive process — and a single point of contact through to the notarised deed.
