Buying a multi-unit building in Belgium: complete guide
How to buy a multi-unit building in Belgium: prices, yield, financing, management and pitfalls to avoid for this multi-lot investment.
What is a multi-unit building and why invest
A multi-unit building is an entire building containing several rental units. Unlike buying an apartment in co-ownership, the investor is the sole owner and decision-maker.
| Criterion | Single apartment | Multi-unit building |
|---|---|---|
| Gross yield | 4-5 % | 6-10 % |
| Vacancy risk | 0 or 100 % | Spread across several units |
| Works decisions | General assembly vote | Free |
| Management | Simple | More complex |
| Price per sqm | Market | Often lower |
The Belgian market offers opportunities, notably in mid-sized cities in Wallonia and outer-ring municipalities of Brussels.
Advantages and yield
Superior yield
The multi-unit building offers better returns thanks to a lower price per sqm and shared charges. Recoverable charges are split between tenants.
Yield simulation
| Item | Annual amount |
|---|---|
| Gross rents (4 units x EUR 700) | EUR 33,600 |
| Non-recoverable charges | -EUR 3,000 |
| Property tax | -EUR 2,500 |
| Vacancy (5 %) | -EUR 1,680 |
| Routine maintenance | -EUR 2,000 |
| Net income before tax | EUR 24,420 |
For a purchase at EUR 350,000, the net yield reaches 7 % before income tax. The leverage effect further amplifies the return on equity.
Financing a multi-unit building
Banks analyse the file differently from a primary residence:
| Element | Typical requirement |
|---|---|
| Personal contribution | 25-30 % of price + fees |
| Debt-to-income ratio | Max 50 % (income + weighted rents) |
| Rent weighting | 70-80 % of gross rents |
| Loan term | 15-25 years |
The credit vs cash question deserves careful analysis. In a low-rate environment, borrowing maximises the return on equity.
Managing a multi-unit building day to day
Managing a multi-unit building is more demanding than a single property: multiple leases to track, multiple inventories of fixtures, works to coordinate.
Management options
| Option | Cost | Best if |
|---|---|---|
| Self-management | EUR 0 | You have time and live nearby |
| Management software | EUR 10-30/month | You self-manage but want automation |
| Letting agency | 5-8 % of rents | You lack time or live far away |
A rental management software centralises leases, rent receipts and communications for each unit.
