In Saint-Gilles, Ixelles, and other communes with a high share of tenants, it’s common to want to sell a property that is still occupied under a lease. Contrary to popular belief, a sale does not cancel the lease: the tenant keeps specific rights, and the buyer inherits them. Understanding these rules before listing a property avoids unpleasant surprises, protects the relationship with the tenant, and helps target the right type of buyer.
The Principle: A Sale Does Not End the Lease
The lease remains fully in effect until the day the notarial deed is signed. On that day, the buyer automatically becomes the new landlord, taking over the seller’s rights and obligations under the same terms as the original lease (rent, duration, charges). A seller cannot use the sale as a pretext to end the lease before the deed is signed, nor promise a buyer the property will be vacant at signing if the lease is still running.
Registered or Not: A Difference That Changes Everything
This is the most decisive factor, and often the least understood by owners.
If the lease has been registered (a free, legal obligation on the landlord), it has a “certain date” and becomes enforceable against the buyer: the buyer must honor it until its normal term, exactly as the seller would have had to. The only exception is a short-term lease (3 years maximum): if registered, the buyer can terminate it starting from the second year, with 3 months’ notice and compensation.
If the lease was never registered, it has no certain date and tenant protection against the new owner is weaker: if the tenant has occupied the property for less than 6 months, the buyer can end the lease without cause or compensation; if occupation has lasted 6 months or more, the buyer can give 6 months’ notice for personal occupation, provided the tenant is notified within 6 months of the signing of the notarial deed.
Practical takeaway for a seller: a properly registered lease reassures an investor-buyer (guaranteed, predictable rental income) but may deter a buyer who wants to move in quickly.
Notice for Personal Occupation: Conditions and Timelines
Whether it’s the seller before the sale or the buyer afterward, a landlord may terminate a 9-year lease early to personally occupy the property, or have a close relative occupy it (spouse, children, parents, up to the third degree depending on the case). This notice requires a 6-month period and must clearly state the identity and relationship of the person who will occupy the property. If the stated reason turns out not to be genuine, the landlord risks compensation of up to 18 months’ rent to the affected tenant. This rule protects both the tenant and a good-faith buyer: a personal occupation reason must be real, not a pretext to free up the property faster.
The Tenant’s Right of First Refusal Since 2024
Since 6 January 2024, a regional ordinance grants tenants a right of first refusal when their main residence in Brussels is sold (excluding short-term leases of 3 years or less). In practice, the owner must offer the property to the tenant first, at market price and conditions, before selling to a third party. The tenant has 30 days to respond. If they decline and the property is later sold at a lower price or on more favorable terms, the right of first refusal is reactivated with a 7-day window. If this step was skipped earlier in the process, the notary is required to notify the tenant with a copy of the signed preliminary agreement at least 60 days before the deed is passed, which can noticeably delay a poorly planned sale.
For a seller, this means building this step into the sale timeline from the start, rather than discovering it midway through a preliminary agreement.
Impact on Price and Buyer Profile
A property sold occupied attracts a different type of buyer than one sold vacant:
- The buy-to-let investor: looks for stable returns, values a registered lease and a market-rate rent, and is less concerned that the property is occupied.
- The owner-occupier buyer: usually wants to move in quickly; an existing lease, especially one that’s registered and recent, can put them off or lead them to negotiate a discount.
- The price discount: according to market practitioners, an occupied property typically sells for 5% to 20% below an equivalent vacant property, with the gap depending on the lease’s remaining term, the rent level, and the current tenant’s creditworthiness.
In Saint-Gilles or Ixelles, where the share of rented housing is high, positioning a rented property toward the right buyers (investors rather than first-time occupants) often avoids this unnecessary discount.
In Summary
Selling a rented property in Brussels is entirely possible, but it requires specific preparation: checking whether the lease is registered, planning ahead for the tenant’s right of first refusal in place since 2024, and targeting the right type of buyer given the rental situation. A sale well prepared on these points protects the seller, respects the tenant’s rights, and avoids last-minute holdups at the notary’s office.
