The 3 rental management methods

Every Belgian landlord must choose how to manage their property: entrust the management to an agency, use online software, or do everything themselves. Each method has its advantages, costs and limitations.

Real cost of the agency

For a rent of 800 EUR/month, the agency costs 576 to 768 EUR/year. That is the equivalent of 0.6 to 0.8 yield points. On a gross yield of 4.3%, the agency brings the net yield down to 3.5 to 3.7% (before other charges).

The rental management agency

What it does

  • Tenant search and selection (viewings, creditworthiness checks)
  • Lease drafting and inventory of fixtures
  • Rent collection and arrears monitoring
  • Repair and technical emergency management
  • Annual indexation and lease renewal
  • Communication with the tenant

The costs

  • Management commission: 6 to 8% of the monthly rent (excluding 21% VAT)
  • Letting fees: 1 to 2 months’ rent (at each tenant change)
  • Miscellaneous fees: inventory of fixtures (200-400 EUR), works management (10% of the amount)

When to choose the agency

  • You live far from the property (expat, remote investor)
  • You have neither the time nor the desire to manage tenants
  • The property is in a tight market where vacancy is a real risk
  • You have 5+ properties and management becomes too time-consuming
Watch out for hidden fees

Some agencies charge additional fees for each intervention: arrears reminders, sending letters, claims management. Read the management mandate contract in detail before signing.

Rental management software

What it does

  • Rent tracking (deadlines, automatic reminders, receipts)
  • Automatic indexation compliant with Belgian law
  • Compliant lease creation in line with regional legislation
  • Document storage and management (lease, inventory of fixtures, certificates)
  • Communication with the tenant
  • Financial dashboards (yield, charges, taxation)

What it does not do

  • Tenant search and selection
  • Property viewings
  • On-site technical interventions
  • Emergency management (leak, boiler failure)

When to choose software

  • You manage 1 to 10 properties and want to stay in control
  • You are available for viewings and occasional emergencies
  • You want to automate day-to-day management without paying 6-8% of the rent
  • You invest in your region and can travel

Self-management

The advantages

  • Zero cost: no commission, no subscription
  • Total control: you choose the tenant, set the conditions, manage the relationships
  • Property knowledge: you know every detail of your property

The risks

  • Legal errors: incorrect indexation, non-compliant lease, forgotten registration
  • Considerable time: 5 to 10 hours per month per property (tenant search, day-to-day management, repairs)
  • Emotional management: conflicts with tenants are harder to handle without an intermediary
  • Oversights: missed deadlines, lost documents, unmet obligations

Self-management is viable for 1 to 2 properties if you have time and legal knowledge. Beyond that, the risk of error and the time invested no longer justify the savings made. A professional lease is the bare minimum, even with self-management.

Which management method to choose?

Rental management software represents the best compromise for the majority of Belgian landlords: modest cost, legal compliance, significant time savings and total control over management.

The agency is mainly justified for remote landlords or large portfolios. Pure self-management is a risky choice beyond 2 properties without a tracking tool.

Methodology

Comparison based on average fees of rental management agencies in Belgium (IPI 2025 survey), prices of the main management software (published rates), and estimated DIY management time (CIB 2025 survey). Calculations based on a 2-bedroom flat with a rent of 800 EUR/month.

Frequently asked questions

  • Rental management agencies generally charge between 6 and 8% of the monthly rent (excluding 21% VAT). For a rent of 800 EUR, that represents 48 to 64 EUR/month, or 576 to 768 EUR/year. Additional fees often apply for finding tenants (1 to 2 months' rent).

  • Yes, this is the choice of the majority of Belgian landlords. Self-management is free but requires time (5 to 10 hours per month) and legal knowledge. Rental management software considerably reduces time and the risk of errors.

  • For day-to-day management (rents, indexation, documents), yes. For tenant search, viewings and on-site technical interventions, no. Software is ideal for landlords who want to stay in control without spending too much time on it.
