What is the fastest fair way to filter rental applications (for agencies)?

The fastest fair way is three passes with rules you wrote down before the listing went online. Pass one: is the application complete? Pass two: does it fit the listing's rules? Pass three: can the household pay the rent? Each pass uses the same rule for everyone and takes a short look, so you read in depth what remains. On aptari the sorted shortlist covers the three passes: every applicant is rated by the same rules, the facts are shown, and documents are read once at upload. The list sorts. A person at your agency decides, and aptari never declines anyone automatically.

The three passes

PassQuestionRule you wrote down beforehand
1. CompleteIs the form filled in and the debt enforcement extract (Betreibungsauszug) attached?The list of what an application must contain
2. Fits the listingDo the move-in date, the number of people and the pets match the listing?The listing's own rules
3. Ability to payDoes the stated income cover the rent by your ratio, and what does the extract show?Your ratio, for example rent at most one third of gross income

Run each pass over every application, in this order.

What makes it fair

  1. Rules before names. Write the three rules down before the listing goes online.
  2. Criteria tied to the lease. The FDPIC (EDÖB) leaflet on application forms for rental flats, updated 15 July 2025, allows data that serves to choose a suitable tenant by objective criteria. Marital status, religion and nationality are in principle not admissible.
  3. Not every paper from everyone. The leaflet calls that disproportionate. A copy of the extract may be asked of all applicants, proof of income and a copy of the ID of the chosen one.
  4. A reason in one line for your choice, in terms of the three rules.
  5. Tell the others, and destroy their data once the flat is let.

Example

Vacancy stood at 0.93% in Switzerland and 0.11% in the city of Zurich on 1 June 2026 (BFS), so a flat can draw many applications. If 90 arrive and you read each in full at 6 minutes, that is 540 minutes, or 9 hours. With three passes: 90 at 1 minute, then, if 60 remain, 60 at 1 minute, then, if 30 remain, 30 at 4 minutes. That is 90 + 60 + 120 = 270 minutes, or 4.5 hours. An example, not a promise.

How the sorted shortlist does pass one to three

  • Pass one. Documents are read once at upload, and you see what is there and what is missing.
  • Pass two. The listing's smoking and pet rules are part of the rating.
  • Pass three. Income against the rent is part of the rating.
  • Every applicant is rated by the same fixed rules, with the facts shown. Nationality, religion, age and gender are never used.
  • The list sorts. aptari never decides and never declines automatically: a person at your agency does.

Growth costs CHF 499 a month at the launch price (regular CHF 999) for 10 active listings. No setup fee, no fee per applicant.
