Because prices to buy are very expensive in Brussels, or simply because you do not wish to invest in Belgium, you might prefer to rent an accommodation.
There are numerous estate agencies and website specialised in properties in Brussels. For example:
The lease, without any specific notification, is assumed to be agreed for 9 years. At the end of the lease, new periods of 3 years each time are said to be agreed without notification if nobody has terminated the lease. Each time that the lease is extended between the tenant(s) and the landlord(s), the lease continues and the rent cannot be modified at this occasion. Short term leases are equal to or less than 3 years.
It is only possible to change the price of the rent when you change the lease. During the lease, the rent is following a yearly index (i.e. adapting to the cost of living index), that is different from the rise of the rent during the lease. Since 1991, the modification of the rent during the lease is possible but can only happen at the end of each period of 3 years. The change of the rent can be requested by the tenant or by the landlord, solely on a very precise timing. Afterwards, either each part agrees, either they disagree and then the person who submitted the request can go to court.
For more information on leases, it is adviced to check with the information of the federal website.
In addition to the rent, the tenant will often have to pay additional charges:
Fees and charges must be listed with the rent on an additional document.
Three months before the end of the lease, it is possible to give your notice (by recorded letter). If no notice has been done before the end of the contract, the initial lease carries on with the same conditions, but it will be considered to have been agreed for a period of 9 years.
Rental benefits exist in Brussels-Capital Region, in order to help some citizens to find accommodation.
In order to be candidate for social accommodation (equivalent to council estates), the person has to comply with some criteria, especially in terms of maximum income subject to tax. The registration is made using a document from the organisation of the social estate (AIS - agence immobilière sociale). It is also possible to get removal and rent allowance (ADIL).

Litigations and issues regarding the tenacy have to be settled with the juge de paix (see list) of the location where the property is located.
