How to prepare a strong tenant application file
Guide to preparing a tenant application file in Belgium. Authorised documents, professional presentation, common mistakes and free template.
Why a good file makes all the difference
On the Belgian rental market, a landlord receives on average 10 to 30 applications for an attractive property in an urban area. Facing this competition, a complete, readable and professional file is your best asset. It is often the file — and not the viewing — that tips the balance.
A well-prepared file shows the landlord that you are organised, serious and solvent. Conversely, an incomplete or messy file gives the impression of a potentially negligent tenant.
Prepare your file before you even start viewings. Having a file ready on the day of the viewing allows you to hand it to the landlord immediately and get ahead of other candidates.
The essential documents
Mandatory and authorised documents
| Document | Mandatory? | Purpose |
|---|---|---|
| Identity card / residence permit | Yes | Identification |
| Payslips (last 3) | Yes | Solvency |
| Employment contract or certificate | Yes | Professional stability |
| Household composition | Recommended | Number of occupants |
| Tax assessment notice | Depends on profile | Annual income (self-employed) |
| Reference from previous landlord | Optional | Rental history |
For atypical profiles
- Self-employed: latest tax assessment notice + accountant’s certificate + extract from the Crossroads Bank for Enterprises (CBE)
- Students: enrolment certificate + guarantor’s income + surety commitment
- Pensioners: latest pension statement + tax assessment notice
- Expatriates: Belgian employment contract + latest salary slips + employer reference
The landlord cannot ask you for: a criminal record extract, a bank account statement, medical information, a non-indebtedness certificate from the NBB, information about your private life, beliefs or origin. Politely refuse such requests and remind them of the anti-discrimination law.
How to present your file
The ideal structure
Organise your file in this order:
- Cover page: surname, first name, telephone, email
- Cover letter: 5 to 10 lines about your situation and your search
- Identity documents: front and back copy of the identity card
- Proof of income: payslips sorted by date, employment contract
- Household composition: recent document (less than 3 months old)
- References: contact details of the previous landlord (with their consent)
Paper and digital versions
Prepare both versions:
- Paper: plastic folder or cardboard wallet, documents in transparent sleeves
- Digital: a single PDF file named “File-SURNAME-FirstName.pdf”, sent by email right after the viewing
The cover letter
Stay factual and concise. Mention:
- Your professional situation (type of contract, seniority, employer)
- The reason for your search (transfer, first home, growing family)
- The desired rental duration
- The number of occupants

The 5 mistakes that ruin a file
Mistake 1: outdated documents. Your payslips must be from the last 3 months. A household composition certificate older than 3 months will be considered obsolete by the landlord.
Mistake 2: an incomplete file. A missing document forces the landlord to chase you. Meanwhile, they move forward with other candidates. Check your checklist before each submission.
Mistake 3: too much personal information. Do not provide unrequested documents (bank statements, medical file). This can be perceived as overcompensation and raise questions.
Mistake 4: careless presentation. Documents in disarray, illegible scans, email without a subject line — these details betray a lack of care that the landlord will project onto your management of the property.
If your rent represents more than 33% of your net income, anticipate the question. Offer a guarantor, a bank guarantee or explain why your fixed costs are low (no loan, no car). Transparency is reassuring.
Mistake 5: lying about your income. The landlord can verify the information. A discovered lie permanently ruins your application and can constitute grounds for the nullity of the lease.
Tips to stand out
React quickly
Send your file by email within the hour following the viewing. Accompany it with a thank-you message reminding the landlord of your interest in the property and your strengths (stability, non-smoker, no pets if relevant).
Show your reliability
- Arrive on time for the viewing
- Ask relevant questions (charges, planned works, neighbourhood)
- Show that you know your tenant rights without being aggressive
Offer a solid guarantor
If your income is tight, the presence of a solvent guarantor can tip the decision in your favour. Add to the file the guarantor’s identity card, their payslips and a signed letter of commitment.
Use the right tools
To facilitate the management of your applications and your future lease agreement, consider online tools that centralise the process. A digitised and well-structured file is also easier to adapt for each application.
Frequently asked questions
-
In Belgium, the landlord may request: the identity card, proof of income (payslips, tax assessment notice), employment contract and household composition. They cannot request a criminal record, bank statement, account extract, medical file or information about ethnic origin or private life.
-
The standard practice is to provide the last 3 payslips. Some landlords ask for 6. If you are self-employed, provide the latest tax assessment notice and a certificate from your accountant.
-
The unwritten rule is that rent should not exceed one third of the household's net income. This is not a legal obligation, but a ratio of 30 to 33% reassures landlords. If your income is tight, a guarantor or bank guarantee can compensate.
-
The landlord is free to choose their tenant, but they cannot discriminate on the basis of protected criteria (origin, disability, marital status, sexual orientation, etc.). The refusal must be based on objective criteria such as solvency or a household composition unsuited to the property.
