Are You Paying More Rent Than Allowed?
In Switzerland, tenants overpay on average by more than CHF 360.– per month. For your initial rent, you only have 30 days to fight back.
What you can do if you're affected.
30 days. No more.
For the initial rent, the deadline starts on key handover, and not on contract signing.

What you can do if you want to help.
Because Uncertainty Is Not a Personal Failure.
Not every rent is unfair. Not every situation is solvable. But every decision should be based on understanding — not on being overwhelmed or pressed for time.

The 30-Day Deadline
You can only challenge your initial rent within 30 days of receiving the keys, even if you've already signed the contract. After that, you're stuck.
The Burden of Proof Lies With You as the Tenant
To demand a reduction, you need evidence. We collect real rental data so you can make your case.
Usurious Rents Are Prohibited
The Federal Court sets a clear maximum return. Many owners don't comply. On average, you pay over CHF 360.– too much every month.
