Sophie’s situation

Sophie has found a 2-bedroom apartment in Namur that matches her investment criteria. The price is attractive — 10% below market value. The reason: the property is occupied by a tenant who has been in place for 4 years, with a 3-6-9 lease registered at the FPS Finance.

Sophie has two questions:

  1. Can she give notice to the tenant to occupy the property herself?
  2. If she keeps the tenant, what are her obligations?

The registered lease is the key to the situation. Registration makes the lease enforceable against the new landlord: Sophie is bound to respect the lease under the same conditions as the seller.

Tenant’s rights in case of sale

The sitting tenant benefits from significant protections:

RightRegistered leaseUnregistered lease
Right to remainYesNot guaranteed
Same lease conditionsYesNo
Landlord’s notice period6 months (motivated)3 months (without grounds)
Indemnity for notice without grounds9-18 months’ rentNone
Rental deposit protectionYesYes

The new landlord cannot:

  • Increase the rent (except normal indexation)
  • Modify the lease clauses
  • Require a new contract or amendment
  • Evict the tenant without legal grounds
Registered lease = maximum protection

If the lease is registered, the tenant has near-absolute protection. The new landlord must respect the lease until its expiry. This is why it is essential to check the registration before purchasing.

New landlord’s obligations

Before purchase

  1. Check the existence of current leases (ask the seller)
  2. Consult the registration register at the FPS Finance
  3. Obtain a copy of the lease and the property inventory
  4. Check the rent payments: amount, payment regularity, possible arrears
  5. Assess the discount: a property with a sitting tenant sells for 5-15% less

After purchase

  1. Inform the tenant of the change of owner (recommended)
  2. Provide new bank details for rent payment
  3. Take over the rental deposit from the seller
  4. Register the deed of sale at the mortgage office
  5. Assume the lessor’s obligations: maintenance, repairs, landlord insurance

To manage the transition effectively, a rental management software centralises the lease, deposit and receipts.

Practical advice

For the investor-buyer

  • A property with a sitting tenant is a good investment: immediate income, no vacancy
  • Check the tenant’s creditworthiness (payment history)
  • Calculate the yield based on the current rent (not on a hoped-for rent after the tenant leaves)
  • See our guide on property investment in Belgium

For the owner-occupier buyer

  • A property with a tenant is more complex: you will not be able to occupy it immediately
  • Give notice for personal occupation from the purchase date (6-month notice period)
  • Budget the potential indemnity if you give notice without grounds
  • Prefer properties with a short-term lease close to its expiry
