Switzerland's rental process has a lot of paperwork, but it is predictable once you know the seven steps. Here is the whole thing, start to finish.
Step 1 · Work out your budget
Swiss landlords usually want a gross income of at least 3 times the rent. For a CHF 2,000 apartment, that means around CHF 6,000 a month before tax. Remember to add Nebenkosten (utilities and service charges) on top; in the city of Zurich, gross rents are about 10 to 15% above net rents (Statistik Stadt Zürich, 2026).
Step 2 · Get your documents together
You will need: ID or passport plus your permit, your last few salary slips, a debt extract (Betreibungsauszug, less than 3 months old), a reference from a previous landlord, and proof of liability insurance. See what documents you need. It helps to upload these once into your aptari Tenant Passport: on listings from aptari partner agencies they go out with Passport Apply (as soon as partner agencies list on aptari; none have yet), and for every other listing you have them in one place.
Step 3 · Search the listings
The big listing sites are Homegate, ImmoScout24 and Flatfox. Checking each one separately is slow. aptari shows you listings from Homegate, ImmoScout24, Flatfox and cooperative websites in one open feed and puts a Match Score next to each, so you can see at a glance which flats are worth your time.
Step 4 · Apply fast
A popular listing can draw many applicants in a single day, and a complete dossier sent early often has the edge. On listings from aptari partner agencies you tap Passport Apply and your saved dossier goes to the agency in one click (5 a month on Basic, unlimited on Pro and Ultra, which also draft a cover letter in the listing's language), as soon as partner agencies list on aptari; none have yet. On listings from other Swiss portals and from cooperatives, Apply with Aptari prepares your message wherever the button shows, and you send it there.
Step 5 · Go to the viewing
Group viewings (Massenbesichtigung) are common. Arrive on time, be friendly, and bring a printed copy of your dossier as backup.
Step 6 · Sign the lease and pay the deposit
Once you are chosen, you sign the lease (Mietvertrag) and pay the deposit into a blocked account (Sperrkonto) in your own name. By law it is capped at 3 months' rent. See how the deposit works.
Step 7 · Register
Within 14 days of moving in, register at your local residents' office (Einwohnerkontrolle).
Why applications fail
Three reasons account for many rejections: the rent is more than about a third of your gross income, the Betreibungsauszug is old or shows open entries, or the cover letter is a generic copy. Avoid all three and you are ahead of many applicants. In the cover letter, write in the language of the listing and say how long you plan to stay: landlords value stability.
The checklist
Before applying: the documents from step 2 · a budget of about a third of your gross income · your must-haves (rooms, area, pets, parking).
When applying: send the complete dossier as early as you can · a short, specific cover letter · keep track of where you applied.
At the viewing: arrive on time · bring a printed dossier as backup · note defects you can see · ask what the Nebenkosten include.
At signing: read the lease (notice period, house rules, pets) · record every defect in the handover protocol and photograph it · pay the deposit into a blocked account in your name · keep a copy of the protocol.
After moving in: register with the residents' office within 14 days · set up electricity, internet and the Serafe radio and TV fee · consider household contents insurance (Hausrat).
How aptari makes this easier
aptari is a Swiss apartment platform for steps 2 to 4. Save your Tenant Passport once, see your Match Score (0 to 100, based on your income against the rent, your checked documents and the listing's smoking and pet rules) on every listing, and apply with one click on listings from aptari partner agencies. On the Ultra plan, the Apply Agent applies for you automatically to partner listings you fit, as soon as partner agencies list on aptari; none have yet.
aptari is free to start: Basic is CHF 0 forever (the open feed, 5 Match Scores a day, and on partner listings unlimited form applications and 5 Passport Apply a month), Pro is CHF 9.90 a month (launch price, normally CHF 15.90), and Ultra is CHF 69 a month (launch price, normally CHF 129). New users get a 14-day free Pro trial. Your documents are handled safely. Your data is stored in the EU (Frankfurt); some processing is done by providers in the USA, see the privacy policy.
