Rental yield is the key indicator of any property investment. In Belgium, we distinguish between gross yield (annual rent / purchase price) and net yield (after deducting charges, taxes and vacancy).
Yields vary significantly by location:
- Brussels: 3.5-4.5% gross — strong rental demand but high prices
- Flanders: 3-4.5% gross — stable market, good quality tenants
- Wallonia: 5-7% gross — low purchase prices but higher vacancy rates
Key figure — For a EUR 200,000 apartment rented at EUR 850/month in Brussels, the gross yield is 5.1%. After deducting charges (withholding tax, insurance, maintenance, vacancy), the net yield drops to approximately 3.2-3.8%.

Belgian banks typically finance a property investment at up to 80% of the property value (loan-to-value), compared to 90-100% for a primary residence. The minimum deposit required is therefore 20% of the purchase price plus acquisition costs (12-15%).
Mortgage rates for investment properties are slightly higher than for primary residences, typically 0.10 to 0.30% more. The maximum debt-to-income ratio is set at 50% of net income by the National Bank of Belgium.
Good to know — Some banks offer bullet loans (capital repayment at maturity) that can optimise monthly cash flow. Bridge loans are also an option if you are selling one property to purchase another.

The choice of property is decisive for investment success. The essential criteria are: location (proximity to transport, shops, schools), property type (1-2 bedroom apartment for yield, house for capital gains), property condition (new vs renovation project) and EPC rating.
One or two-bedroom apartments in urban centres offer the best yield-to-liquidity ratio: strong rental demand, reduced vacancy and easier resale. Studios present higher gross yields but greater tenant turnover.
Note — Registration duties differ by region: 12.5% in Wallonia and Brussels (6% with primary residence abatement), 12% in Flanders. These costs significantly reduce net yield in the first year.

Rental management can be handled by the owner or delegated to a letting agency (average cost of 5-8% of rent). Direct management maximises yield but requires time: finding tenants, inventory of fixtures, payment tracking, repair management.
To optimise long-term profitability, the investor should minimise vacancy (well-maintained property, market-rate rent), anticipate works (recommended working capital of 2-3 months’ rent) and adapt the property to regulatory changes (EPC standards, smoke detectors, etc.).
Key figure — In Belgium, the average vacancy rate is 4-6% for well-located properties, but can reach 10-15% in less sought-after areas. Each month of vacancy reduces the annual yield by 0.4 percentage points.
