A Comparis survey puts a first number on how far housing demand is leaking across the border. Meanwhile the reference rate stays stuck at 1.25% and Vaud counts 3,907 empty homes.

A survey has finally put a number on how far Swiss housing demand is drifting across the French border. Around 92,400 French-speaking Swiss, 4.2% of that population, are actively looking for a home in France rather than at home.
Innofact ran the survey for Comparis in May 2026 among 1,001 people, and RTS reported it this week. It puts at 4.2% of the French-speaking population the share actively searching on the far side of the border, in Haute-Savoie and the Ain.
The rest of the survey shows where that number comes from. 70% of respondents find rents or purchase prices in their region too high, and 30% of French-speaking adults are seriously considering a move to France, according to 20 minutes.
The gap between the three bars is the real finding. Discontent is close to universal, the intention stays a minority position, and an actual search concerns one person in twenty-four. For that last group, moving to France from Switzerland has stopped being a thought experiment. The pool of people who could still leave remains wide.
What the survey does not measure is how many of those searches end anywhere. A lease signed in Haute-Savoie leaves no trace in Swiss housing statistics. These are stated intentions, then, not recorded moves.
CANTON OF GENEVABecause nowhere else in the country does housing feel this expensive. Half of the Geneva respondents rate housing costs as “very high”, against 10 to 12% in cantons such as Bern, Jura or Valais, in the same survey.
Geography does the rest. The shift concentrates around the Lake Geneva basin, towards Haute-Savoie and the Ain, where a daily commute stays workable for anyone keeping a job on the Swiss side.
For a Geneva owner, the indicator to watch over the coming quarters is not the price per square metre. It is the depth of the rental market, which sets the yield an investor is willing to pay for a building.
FEDERALNothing points that way. The mortgage reference rate, the one that opens the right to a rent reduction, has stood at 1.25% since 2 September 2025, and the 2 June 2026 review confirmed it unchanged (Federal Housing Office).
The mechanism is written in advance and cuts both ways. A 0.25 point change is worth a 2.91% rent reduction claim for the tenant, or a 3% increase for the landlord.
| Move in the reference rate | Change allowed on the rent |
|---|---|
| Down 0.25 point | −2.91% |
| Up 0.25 point | +3.00% |
The lease still has to qualify. The reference rate leaves four categories aside.
On the monetary side, the Swiss National Bank held its policy rate at 0.0% on 18 June 2026, a fourth consecutive hold. The Bern cantonal bank expects rates to stay put until the end of 2026 if the economy and inflation stay contained, with no significant move on short-term fixed mortgages.
So for anyone renewing a lease or negotiating a mortgage this year, the variable to watch is not the central bank. It is the rental market itself, which is precisely where the pull towards France lands.
CANTON OF VAUDOn 1 June 2026 the canton of Vaud recorded 3,907 vacant dwellings, a provisional rate of 0.87%, down 0.02 point year on year (Vaud housing observatory). We published the national vacancy rate as of 1 June 2025, at 1.00%, in late July. The Vaud figure updates it, on a narrower perimeter and a more recent year.
The breakdown carries more weight than the rate. Of those 3,907 dwellings, 1,172 are offered for sale only, not for rent. A Vaud owner putting a property on the market therefore faces a different scarcity from a landlord looking for a tenant.
Spread across a whole canton, 1,172 properties for sale leave thin competition for a seller. The figure is provisional, and it says nothing about how those properties split between districts.
IN BRIEFA 4.5-room flat in Zurich advertised at around CHF 2,700 a month went round social media this week. The landlord required an unusual advance payment from the future tenant before they had even moved in, which set off a wave of criticism about how applicants are screened (Blick).
The rule applies across Switzerland, Zurich included. Rent falls due on the agreed date, not upfront as a condition of getting the flat. The one advance payment with a legal framework is the deposit, capped as a rule at three months of rent under article 257e of the Code of Obligations, held in a blocked account in the tenant’s name.
