Why co-tenancy pays more

Co-tenancy is one of the most profitable strategies in Belgian rental investment. The principle is simple: rent a property by the room rather than to a single household.

University cities (Brussels, Louvain-la-Neuve, Liege, Ghent) offer the best markets for co-tenancy. See our guide where to invest in Brussels for promising neighbourhoods.

The co-tenancy lease in Belgium

The legal framework varies by region. In Brussels, the housing lease ordinance provides a specific regime for co-tenancy since 2018.

Single lease vs individual leases

Single lease + joint liabilityIf one tenant defaults, the others are liableComplex replacement
Individual leasesIndependent management per roomNo joint liability

The co-tenancy lease must include a co-tenancy pact defining the allocation of charges and house rules. The rental deposit is individual per tenant.

Managing a co-tenancy day to day

Turnover: the main challenge

Co-tenants stay on average 12 to 18 months. Each departure involves a partial inventory of fixtures, the release of the deposit and the search for a replacement.

Optimising management

A rental management software is essential for tracking multiple tenants, automating rent reminders and managing move-ins and move-outs. Charges in co-tenancy are generally managed on a flat-rate basis for simplicity.

Taxation

Co-tenancy does not trigger a different tax regime for the landlord. Taxation remains based on the cadastral income if all tenants are natural persons.

Verdict: co-tenancy as an investment strategy

Co-tenancy offers a significantly higher yield than standard letting, provided you accept more active management. It is an ideal strategy for investors in university cities who are ready to manage turnover.
