Apartment application package: what mistakes should I avoid?
Typical mistakes when putting together a Swiss apartment application package, avoidable pitfalls and a checklist – for Hungarians looking for housing in Switzerland.
What is a rental application package and why is it necessary?
On the Swiss rental market – especially in the major cities – demand far outstrips supply. In Zürich, Genève and Basel, a single advertised apartment typically attracts 50–200 applications. Landlords and property management offices (Verwaltung) therefore use the Bewerbungsdossier as a screening tool: anyone who does not submit a complete, well-organized package is often ruled out by the office even before a viewing.
The package is not just a formality. On the one hand, it has a legal function: based on the debt collection extract (Betreibungsregisterauszug) and proof of payment, the landlord can assess whether the tenant is really able to pay the rent. On the other hand, it also serves a communication purpose: a well-prepared package signals that the applicant is serious, organized and reliable.
From a Hungarian perspective, this is important: if you have just arrived in Switzerland, or have been living there only a short time, putting the package together can be especially challenging. You may not yet have a Swiss employer confirmation, there may be no entry yet in the local debt register (which is positive, but still needs to be demonstrated), and your previous landlord reference may come from another country. These situations can be handled – but you need to know how.
Typical mistakes when putting the documents together
Missing or outdated debt collection extract
The debt collection extract (Betreibungsregisterauszug) is the most critical element of the package. It is an official extract from the debt collection register (Betreibungsregister) for your place of residence, issued by the local debt collection office (Betreibungsamt). Most landlords accept an extract that is no more than 3 months old.
Typical mistakes:
The applicant submits an extract from a previous place of residence instead of the current one.
The extract is older than 3 months.
People who have just arrived in Switzerland do not know that they need to request it from the Betreibungsamt at their new place of residence – where, of course, there is not yet any entry, but the empty extract proves this and is acceptable.
The extract is not translated if it comes from another canton or language region (although within Switzerland this is rarely necessary, the landlord may still ask for an explanation).
The extract can be requested in person, by post, or in many cantons online as well. The fee varies by canton, typically ranging from CHF 17 to CHF 25.
Outdated or incomplete proof of payment
Landlords usually ask for the last 3 months of salary statements (Lohnausweis / Lohnabrechnung). Typical mistakes:
Only 1–2 months of statements are included in the package.
The statement does not show the employer’s name, or the document does not include the net amount.
Self-employed applicants or business owners do not attach a tax return or an accountant’s confirmation – without these, the landlord has no way to verify income.
People who have just started a job and do not yet have 3 months of Swiss payslips do not attach the employment contract (Arbeitsvertrag) as a supplement.
If you are in your first few months at your new job, the employment contract and the employer confirmation (Arbeitsbestätigung) can partly make up for the missing payslips – but it is worth mentioning this in a cover letter as well.
Missing copy of ID and residence permit
The landlord wants to verify that the applicant is legally residing in Switzerland. As a Hungarian citizen (EU citizen), you are entitled to work and live in Switzerland under the Agreement on the Free Movement of Persons (FZA – Freizügigkeitsabkommen, 1999), but you must present your residence permit (Ausländerausweis, typically type B or L).
Typical mistakes:
Only a copy of the passport is attached, not the residence permit.
The residence permit has expired and renewal is in progress – this must be confirmed with a receipt from the Migrationsamt.
New arrivals who do not yet have a permit do not indicate that the application is in progress.
Missing or weak cover letter
In Switzerland, attaching a cover letter (Motivationsschreiben or Begleitschreiben) to a rental application is not mandatory, but it is strongly recommended – especially in a competitive market. A package without a cover letter remains anonymous and impersonal.
Typical mistakes:
The cover letter is missing.
The letter is generic and doesn’t say anything about the specific apartment or landlord.
The letter doesn’t include relevant information: who the applicant is, how many people would move in, whether there are pets, and when move-in would be possible.
The letter is not written in the language of the application package (it should be written in the language of the landlord’s region — German, French, or Italian).
An untidy, hard-to-read application package
Landlords and agencies value how well a physical or digital application package is organized. An unbound, unnumbered package with documents in mixed order makes a bad impression.
Typical mistakes:
The documents are not arranged in a logical order.
The photocopies are unreadable or cut off.
In a digital package, the file names are meaningless (e.g. “scan001.pdf").
The package is unnecessarily bulky: irrelevant documents (for example, old school certificates nobody asked for) dilute the essential content.
Risks: rejection, delays, and financial consequences
The direct consequence of an incomplete package is rejection — but the indirect consequences are also significant.
Delay: If the package is incomplete, the agency will ask for the missing documents. This can take days or even weeks, and in the meantime other applicants may get ahead of you. In the Swiss housing market, speed is also a competitive factor: many agencies give priority to the first complete application package they receive.
Financial consequences: If the apartment search drags on, the costs of temporary accommodation (hotel, Airbnb, sublet) can add up quickly. In Zürich, a one-room temporary stay can cost CHF 2,000–4,000 per month.
Reputational risk: In Switzerland, the network of property management agencies is small, especially in smaller towns. A poorly prepared package is not immediately “forgotten” — the applicant’s name may remain in the agency’s records.
Debt register risk: If someone has an entry in the Betreibungsregister, it cannot simply be erased — it can only expire over time (active entries are usually deleted after 5 years, but this varies by canton and by type of entry). This is one of the most serious obstacles to renting an apartment in Switzerland.
Decision criteria: what should be clarified with the landlord in advance
Before putting the package together, it is worth clarifying a few questions — by phone or email:
Question | Why it matters |
|---|---|
Which documents do they require exactly? | The list varies from agency to agency; there is no need to attach unnecessary documents |
Do they accept a digital application package? | Some agencies accept applications only by post |
What is the application deadline? | Many listings have a short window (3–7 days) |
How many months’ deposit do they require? | In Switzerland, the legal maximum deposit (Mietkaution) is 3 months’ rent, but the amount and form (bank guarantee vs. cash) can vary |
Is pets prohibited? | This must be disclosed in advance — there are no surprises later |
When is move-in possible? | If the date you specify does not match the landlord’s expectations, your application may be rejected outright |
Cantonal and municipal differences: what you need to know about your region
In Switzerland, apartment rentals are regulated uniformly at federal level (the relevant chapter of the Obligationenrecht / OR, the Code of Obligations), but in practice — the range of documents required, office expectations, and the intensity of market competition — varies significantly from canton to canton and city to city.
Zürich and its surrounding area: The most competitive market. Offices typically expect a complete, well-organized package, and incomplete applications are automatically rejected. Online application platforms (e.g. Homegate, ImmoScout24) dominate; a digital application package is standard.
Geneva (Genève) and the canton of Vaud: French-speaking region; the cover letter must be written in French. The market is also heavily oversubscribed. Local tenant-protection rules (e.g. limits on rent increases) are stronger than in other cantons, which paradoxically further tightens supply.
Bern: Bilingual canton (German and French). The market is somewhat less tight than in Zürich, but the documentation requirements are similar.
Basel (Basel-Stadt and Basel-Landschaft): Strong industrial and pharmaceutical job market; many expat applicants. Offices are used to foreign documents, but a Swiss debt register extract is still expected here as well.
Smaller towns and rural areas: Competition is more moderate, but documentation requirements are not necessarily looser. Some smaller offices expect a more personal approach — the cover letter and personal introduction can carry particular weight here.
Important: the Betreibungsregisterauszug must always be requested from the Betreibungsamt of your current place of residence, not from your previous or future one.
Checklist: completeness criteria for the application package
The list below reflects the expectations of most Swiss landlords and property management offices. Some offices ask for less, others for more — always check the conditions in the specific listing.
Required items (in almost all cases):
[ ] Debt register extract (Betreibungsregisterauszug) – no older than 3 months, from the current place of residence
[ ] Copy of identity document (passport or ID card)
[ ] Copy of residence permit (Ausländerausweis B or L) – if you have one
[ ] Last 3 months’ payslips (Lohnabrechnung)
[ ] Completed application form (Bewerbungsformular) – if the office provides one
Strongly recommended items:
[ ] Cover letter (Motivationsschreiben) – in the language of the region
[ ] CV (short, 1 page) – optional, but can give you an edge in a competitive market
[ ] Employment contract or employer confirmation (Arbeitsvertrag / Arbeitsbestätigung)
[ ] Reference letter from your previous landlord (Referenzschreiben des bisherigen Vermieters)
Required in special situations:
[ ] For self-employed applicants: tax return (Steuererklärung) or confirmation from an accountant
[ ] For newcomers: confirmation of the residence permit application
[ ] For multiple tenants (e.g. a couple): documents for each tenant separately
[ ] With pets: note this in the cover letter

In Brief
A Swiss apartment application package works when it is complete, well organized, and tailored to the specific agency. The most common mistakes are a missing or outdated Betreibungsregisterauszug, too few payment slips, no copy of the residence permit, and a weak cover letter. If the package is incomplete, rejection is not the only risk: delays and extra costs can easily arise as well.
Key Takeaways
- The Betreibungsregisterauszug should always be issued by the Betreibungsamt at your current place of residence, and it should not be older than 3 months.
- You should attach the last 3 months of payment slips; if you have only just started a job, the employment contract and employer confirmation can also help.
- If you already have a residence permit, include a copy of it in the package together with your identity document.
- The cover letter should be in the language of the region and should state the number of people moving in, the move-in date, and whether you have a pet.
- It is worth arranging the documents in a logical order, making them easy to read, and avoiding unnecessary attachments.
- Before preparing the package, it is advisable to check whether the agency accepts digital or postal applications, and by what deadline.
Frequently Asked Questions
What is an apartment application package, and why is it requested in Switzerland?
An apartment application package is a set of documents prepared for the landlord that proves the applicant’s ability to pay, lawful residence, and reliability. Because demand is high, landlords often use it to screen applicants even before a personal viewing.
Which is the most important document in the package?
According to the article, the most critical item is the debt certificate, the Betreibungsregisterauszug. It shows whether there is any entry in the debt register, and most landlords only accept an extract that is no older than 3 months.
What should be attached if I do not yet have 3 months of Swiss payslips?
In that case, the employment contract and an employer confirmation can partly replace the missing payslips. According to the article, it is also worth explaining this in the cover letter so the landlord understands the situation.
Is a copy of the passport enough, or is a residence permit also needed?
A copy of the passport alone is not enough if you already have a residence permit. The landlord will usually also want to see a copy of the Ausländerausweis, because it proves the legality of your stay in Switzerland.
Is a cover letter mandatory for a housing application?
It is not mandatory, but the article strongly recommends it, especially in competitive situations. A short letter tailored to the apartment and the language of the region makes the application more personal and more convincing.
What happens if the application package is incomplete?
An incomplete package often leads to rejection, or the agency may ask for the missing documents, which can delay the assessment by days or weeks. In the meantime, this can also increase temporary accommodation costs.
Where should I request the Betreibungsregisterauszug if I have just moved to Switzerland?
You should always request it from the Betreibungsamt at your current place of residence. For people who have just arrived, an empty extract may be accepted, because it shows that there are no entries yet at the new location.
