Method
Why these figures differ from the portals'
Two ways of measuring a market coexist: recorded prices (what was signed at the notary's) and estimated prices (what a statistical model calculates). This page uses the former.
This page
Recorded prices
- Sales signed at the notary's and published in the official register (FAO) : 168 in Cologny over 24 months
- Official ranges by quartiles (OCSTAT, 2024 vintage)
- 18 years of published history (2006–2024), every figure verifiable at the source
Online portals
Estimated prices
- Statistical models (known as “hedonic”): an instant order of magnitude
- Smoothed averages, short history, unpublished methodology
- Useful to get your bearings; insufficient to set an asking price
A model estimates, the register records. Both are useful: we start from the recorded, then an advisor refines according to your property.
Taxation
Selling in Cologny: what the tax says
Property gains tax (IBGI). In Geneva, the gain realised on a sale is taxed from 50% (held less than 2 years) down to 2% (25 years and more, scale in force since 2025). The holding period is often the first lever for optimising the timing of a sale. We calculate it with you before any marketing.
The sale also entails notary fees and possible mortgage exit penalties: a full costing avoids unpleasant surprises on the net seller proceeds.

What is the price per m² of land in Cologny?

An indicative figure: it includes any existing buildings on the plot. No official statistics exist at this level; it is a Nessell calculation on signed prices.
What tax do you pay when selling in Cologny?
The Geneva IBGI, degressive with the holding period: 50% of the gain before 2 years, 2% from 25 years (2025 scale; full exemption has been abolished). The rate is cantonal, identical in every commune. We check the calculation with you before any sale.
Is the housing market tight in Cologny?
Yes. Cologny has 6'149 inhabitants (2025, OCSTAT) for only 27 vacant homes recorded as of 1 December 2025. Demand absorbs the roughly 84 sales concluded each year: a structurally tight market, favourable to sellers.
Is it the right time to sell in Cologny?
The market lends itself to it: prices are holding at a high level (13'436 CHF/m² median, +63% since 2006) and demand remains liquid (~84 sales per year). The right moment depends above all on your situation: holding period (IBGI), next project, works to amortise. That is what the valuation helps you decide.
I inherited a property in Cologny: what should I know?
An inheritance requires a documented valuation: for the declaration, the division between heirs and anticipating the tax in the event of a resale. Nessell provides a written appraisal based on comparable sales in Cologny, and coordinates with your notary if needed.
