How many months’ rent do you have to pay as a security deposit?

If you’re renting a property, the landlord will usually ask you to pay a security deposit. This protects them against damage you might cause to the rented property. Wondering how much a landlord may ask for a security deposit and how you pay it? We've provided a brief word of explanation below.

Is a security deposit required by law?

A security deposit is not a legal requirement. Even so, if your landlord asks you to pay one, it must be explicitly mentioned in your lease. In addition, if you live and rent accommodation in Flanders, you are legally obliged to take out home insurance.

Did you know Kate can also help you with your security deposit?

If you’re looking for a security deposit, just tell Kate: ‘I want to open a security deposit account’. You can find Kate, your digital assistant, in the top-right corner of KBC Mobile.

How much can your landlord ask you to pay as a security deposit?

A landlord may ask you for a security deposit of up to three months' rent. As a tenant, you can legally arrange that deposit in one of four ways:

  • Deposit in a blocked account (the most common way)
  • Personal guarantee
  • Flemish security deposit loan
  • Public Social Welfare Centre guarantee

1. Deposit in a blocked account

You usually put the security deposit on a blocked savings account. That account is in your name (the tenant) and the deposit may not exceed three months' rent.

For example, if you pay 650 euros in rent each month, the landlord may ask you to pay a security deposit of no more than 1 950 euros.

The security deposit remains blocked on the account until the end of the lease. In addition, you (the tenant) receive the interest earned on the security deposit each year. At KBC, you can open a security deposit account online for free, regardless of whether you’re a KBC customer or not.

2. Personal guarantee

A second option is a personal guarantee, where it’s not the tenant that provides a sum of money as security, but instead a person or company that acts as guarantor. Parents do this, for example, for a child who wants to live in his/her own place after graduating from college or university.

If you fail to meet your rental obligations as a tenant, the landlord can call on the guarantee for the equivalent of up to three months' rent. However, the landlord has to agree to this arrangement and is entitled to refuse it.

3. Flemish security deposit loan

If you’re not in a position to pay the security deposit right away, you might be eligible to apply for an interest-free security deposit loan with the Flemish Housing Fund.

Good to know: These loans are anonymous, so the landlord doesn’t know that the tenant is applying for one.

4. A Public Social Welfare Centre guarantee

A final option is to approach the Public Social Welfare Centre (OCMW/CPAS) and ask them to provide a guarantee. They then enter into an agreement with a bank for an amount of up to three months' rent. Again, you have to meet certain conditions to be eligible.

Important: In practice, landlords often ask for the security deposit to be paid in cash or to be credited to their personal account. This is not permitted under the Residential Tenancies Act. As a tenant, therefore, always ask to arrange the security deposit in one of the four ways described above.
