Checking a tenant's creditworthiness in Belgium
How to check a prospective tenant's creditworthiness in Belgium. Rent-to-income ratio, documents to request, warning signs and best practices.
Why check tenant solvency
Unpaid rent is the landlord’s primary financial risk. Verifying solvency before signing the lease is the most effective prevention measure. In Belgium, eviction procedures take 6 to 18 months, during which the landlord bears the full cost.
A proper solvency check reduces the risk of default by 80 %. It also strengthens your position if you ever need to take legal action: you can demonstrate due diligence in tenant selection.
Verification method
Documents to request
- Last 3 payslips (or equivalent income proof for self-employed)
- Employment contract (type: permanent, temporary, interim)
- Latest tax assessment (optional but useful for self-employed)
- Proof of other income (if applicable: pensions, allowances)
What to verify
- Income stability (permanent contract vs temporary)
- Duration of current employment
- Net income vs rent ratio
- Regularity of income (no unexplained gaps)
Income-to-rent ratio
The standard rule of thumb: rent should not exceed one-third of net monthly income. Some landlords accept up to 40 % for well-situated tenants.
| Rent | Minimum net income (33 %) | Minimum net income (40 %) |
|---|---|---|
| EUR 700 | EUR 2,100 | EUR 1,750 |
| EUR 900 | EUR 2,700 | EUR 2,250 |
| EUR 1,100 | EUR 3,300 | EUR 2,750 |
| EUR 1,300 | EUR 3,900 | EUR 3,250 |
For co-tenancy, you can assess the combined income of all tenants if the lease includes a joint liability clause.
Legal limits on solvency checks
Belgian anti-discrimination law restricts what you can request:
| You can request | You cannot request |
|---|---|
| Identity document | Medical records |
| Income proof | Criminal record |
| Employment contract | Bank account balance |
| Landlord reference | Ethnic or religious info |
Apply the same solvency criteria to all candidates. Document your selection process to protect against discrimination claims. See our guide on choosing between candidates.
Making the decision
A solvent tenant with a permanent contract and a rent-to-income ratio below 33 % is the safest choice. If no candidate meets the ideal criteria, consider a guarantor or an additional month of rental deposit.
