Rental value expertise in Brussels

Rental value expertise in Brussels

Determining the appropriate rent for a property in the Brussels-Capital Region requires an objective analysis of the rental market, the condition of the property and its location. Whether you are a landlord wishing to set or revise a rent, a tenant contesting the amount requested, or a legal professional involved in a rental dispute, our real estate appraisal firm produces a certified rental value report in line with Brussels market standards.

The legal framework for rental in Brussels

Residential tenancy in the Brussels-Capital Region

Residential tenancy in Brussels is governed by the Brussels Housing Code (ordinance of 17 July 2003 and subsequent amendments) and the Civil Code provisions relating to leases. The specific rules of the Brussels-Capital Region include:

• 9-year lease: The standard lease is concluded for a term of 9 years, unless otherwise agreed.
• Annual indexation: Rent may be indexed once per year on the basis of the health index, on the anniversary date of the lease.
• Triennial revision: At each three-year interval, the landlord or tenant may apply to the justice of the peace for a rent revision if circumstances have changed (works, neighbourhood changes).
• End of lease: Upon expiry of the 9-year lease, the landlord may freely set a new rent, but it must be in line with the market.

The indicative rent schedule

Since 2017, the Brussels-Capital Region has published an indicative rent schedule that provides, for each type of property and each district, a reference rent range. Whilst this schedule is not binding, it nonetheless serves as a reference tool for justices of the peace in the event of a dispute.

Situations requiring a rental expertise

• Setting the initial rent: You are letting a property for the first time and want a rent that is attractive yet in line with the market.
• Rent revision: At the end of a lease or upon renewal, you wish to adjust the rent to current market conditions.
• Landlord-tenant dispute: The tenant contests the rent or a revised rent. The valuation report constitutes evidence before the justice of the peace.
• Commercial lease: Setting the rent for a commercial premises is governed by specific rules (Commercial Lease Act of 30 April 1951). The expertise determines the objectively assessed rental value.
• Assessment of rental income: In the context of a property investment, the rental expertise allows the actual yield to be calculated and income projections to be validated.
• Tax justification: When the property is let for professional use, the tax authority may contest the declared rent. A valuation report serves as supporting documentation.

Content of the rental valuation report

• Property description: Location, composition, habitable surfaces, state of upkeep, finish level, energy performance (EPC), amenities (parking, cellar, terrace, garden).
• Neighbourhood analysis: Accessibility (STIB public transport), shops, schools, green spaces, socioeconomic profile, vacancy rate.
• Market references: Rents charged for comparable properties in the same district, data from the regional indicative schedule, recent rental listings on property portals.
• Determination of rental value: Objective monthly rent, excluding service charges, for the property in its current condition. The report distinguishes between the furnished and unfurnished cases.
• Yield analysis (if requested): Calculation of gross and net yield based on the fair market value of the property and landlord charges.
