How RentMonitor works

We watch the official Swiss reference rate for you. The moment it drops below the level in your contract, we flag it so you can request a lower rent. When you share a few contract details, we prepare the letter that helps you ask for a fairer rent.

1. We keep watch

Every time the housing authority updates the Swiss reference rate, we record it so you always have the latest figure.

2. You answer a few simple questions

We ask about your rent, move-in date, and address—nothing more complicated. That’s everything we need to check the numbers.

3. We draft your reduction letter

We compare your answers with the latest rate and write the formal letter for you. You download, print, sign, and send it yourself so you stay in control.

4. Wait for your landlord's decision

When your letter arrives, the landlord either confirms the lower rent or writes back to explain why they believe it should stay the same.
