Application guide
Documents to prepare before renting in Belgium
The useful documents that reassure an agency without sharing more personal information than needed.

A prepared file does not guarantee a home, but it prevents delay when an agency asks for information.
Keep documents in a clear folder and only send what is relevant for the stage you are in.
Key points
Prepare identity, income, household situation and references if available.
Hide sensitive information that is not requested.
Give files names an agency can understand quickly.
The basic information
Agencies want to know who will rent, how many people will live in the property and when the lease could start.
An ID document, recent income proof and a short introduction are often enough for a first exchange.
- identity
- income
- household
- preferred move-in date
Income and guarantees
Income can come from salary, self-employed activity, pension or family support. The important part is to explain the situation clearly.
If you have a guarantor, mention it simply without sending every guarantor document in the first message.
Protect your data
Sharing too much personal information too early is not necessary. Mask numbers that are not requested and send sensitive documents only to an identified agency.
A clean file builds trust, but it should remain proportionate.
A practical file with controlled sharing
Prepare a short introduction, contact details and supporting documents relevant to your situation. Information requests can vary by region and application stage; an online checklist does not replace the applicable rules.
Before sending a document, check the source’s identity and why it is needed. Share only necessary information through an appropriate channel, and do not publish your application file in a public comment or openly accessible link.
- Keep your file current.
- Record who received each document.
- Consult official regional tenancy models and information.

Non-exhaustive sample of active public residential listings, deduplicated by Wimmio, from agencies and direct owners. Only known positive euro prices are used. Charges are not harmonized. Sale prices are asking prices, not completed transaction prices.
The median splits prices into two halves. The interval between the first and third quartiles contains the middle half of prices. These figures are withheld below ten listings. A municipality does not mean its entire metropolitan area or region.

Frequently asked questions
Should I send my ID during the first contact?
Not always. You can first introduce yourself, then share documents once the agency asks for them.
Is a guarantor mandatory?
No, but it can help if your income is limited or your situation is recent.
