Rental management: agency vs software vs DIY comparison
Comparison of the 3 rental management methods in Belgium: real estate agency, online software or self-management. Costs, time and risks analysed.
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.
| Criterion | Agency | Software | DIY |
|---|---|---|---|
| Annual cost (800 EUR rent) | 576 to 768 EUR | 108 to 300 EUR | 0 EUR |
| Monthly time | 0 h | 1 to 2 h | 5 to 10 h |
| Tenant search | Included | No | To do yourself |
| Legal compliance | High | High | Variable |
| Control | Low | High | Total |
| Technical emergencies | Managed | Not managed | To manage |
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
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?
| Profile | Recommended method | Annual cost (800 EUR rent) |
|---|---|---|
| 1 to 2 properties, local, available | Software | 108 to 300 EUR |
| 3 to 10 properties, local | Software | 324 to 3,000 EUR |
| 1+ property, remote | Agency | 576 to 768 EUR/property |
| 10+ properties | Agency or in-house team | Variable |
| Zero budget, 1 property | DIY (with professional lease) | 0 EUR + time |
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.

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.
