Positive cash flow in rental property in Belgium: is it possible
How to achieve positive cash flow in rental property in Belgium: calculation, conditions, strategies and concrete examples by region.
Definition and calculation of property cash flow
Cash flow is the difference between rental income and all expenses related to the property. Positive cash flow means the property pays for itself and generates a monthly profit.
Calculation formula
| Item | Monthly |
|---|---|
| Gross rent | +EUR 900 |
| Mortgage payment | -EUR 650 |
| Property tax (monthly equivalent) | -EUR 100 |
| Non-recoverable charges | -EUR 50 |
| Vacancy provision (5 %) | -EUR 45 |
| Maintenance provision | -EUR 30 |
| Net cash flow | +EUR 25 |
This calculation must be realistic: include vacancy, maintenance and non-recoverable charges. Beginner investors often forget the property tax and management fees.
Conditions for positive cash flow in Belgium
The purchase price is decisive
| Region | Average apt. price | Average rent | Gross yield |
|---|---|---|---|
| Brussels | EUR 250,000 | EUR 950 | 4.6 % |
| Wallonia (city) | EUR 140,000 | EUR 700 | 6.0 % |
| Flanders (city) | EUR 220,000 | EUR 850 | 4.6 % |
| Wallonia (rural) | EUR 100,000 | EUR 550 | 6.6 % |
The average rental yield by city shows significant disparities. Wallonia offers the best chances of positive cash flow thanks to low prices.
Interest rate and down payment
The higher the down payment, the more positive the cash flow. The leverage effect is maximised when the gross yield exceeds the total cost of credit.
Strategies for achieving positive cash flow
Co-tenancy
Co-tenancy allows renting a property for 30 to 50 % more than standard letting. A 3-bedroom apartment rented at EUR 900 in standard letting can bring in EUR 1,350 through co-tenancy.
Multi-unit buildings
The multi-unit building offers a lower price per sqm and shared charges. It is the most reliable strategy for generating positive cash flow.
Buying below market
Properties to renovate, inherited properties and judicial sales allow buying 15 to 25 % below market price. After renovation, the yield is mechanically higher.
[!tip] Practical tip Always calculate cash flow over 12 months, not a single month. Include 1 month of vacancy and 1 month of exceptional maintenance to be realistic.
Verdict: is positive cash flow possible in Belgium
Yes, but not everywhere and not with any strategy. Favourable conditions: a low purchase price (Wallonia, properties to renovate), a gross yield above 6 %, a high-yield strategy (co-tenancy, multi-unit building) and a minimum 20 % down payment.
