Where should I advertise my flat for rent in Switzerland, and can I do it for free (for landlords)?

Advertise where renters already search, on a large rental portal, and add the channels that cost nothing. Free options exist. As shown on flatfox.ch on 9 November 2026, up to two adverts at a time are free there. On aptari, the Starter plan costs CHF 0 with 1 active listing and a 14-day Growth trial. Other large portals charge by the week, so the price grows with every week the advert runs. With vacancy at 0.93% in Switzerland (BFS, 1 June 2026), plan for many applications. aptari helps with exactly that part: applications arrive as a sorted shortlist in place of an inbox, and you decide.

For a room in a shared flat, wgzimmer.ch is the usual board.

The same flat is often advertised twice

aptari feed, 9 November 2026: 67,323 rental listings stood for 35,546 different homes, and 60% of the homes were advertised on two or more portals. 20,603 homes were on both Homegate and ImmoScout24. Of 19,179 homes on Flatfox, 9,513 were on neither of the two, about half.

A plan for one flat

  1. Write a clear listing: rent, ancillary costs, rooms, area, move-in date, rules on pets and smoking.
  2. Start with a free advert and your own channels.
  3. Add a paid portal if too few suitable people respond.
  4. Decide beforehand how you will sort the applications. With vacancy at 0.93% in Switzerland and 0.11% in the city of Zurich (BFS, 1 June 2026), plan for many.

Example

If you book a package at CHF 100 a week and the advert runs 3 weeks, it costs CHF 300. If the rent is CHF 2,400 a month, an empty day costs about CHF 80, so an empty week costs CHF 560. Examples, not promises: a free advert that takes a week longer can cost more than a paid one.

What you get on aptari Starter

  • CHF 0, 1 active listing and a 14-day Growth trial. No setup fee, no fee per applicant.
  • A sorted shortlist in place of an inbox: applicants rated by the same rules, facts shown. During the 14-day Growth trial every applicant is rated; after it, Starter includes 5 Match Scores a month.
  • Documents read once at upload.
  • You decide. aptari never decides and never declines automatically.

aptari does not place your listing on other portals. For reach, combine it with the channels above.
