The real cost of a vacant property
Rental vacancy is one of the most underestimated risks of property investment. An empty property does not simply generate zero income — it costs money.
| Item | Approximate monthly cost |
|---|---|
| Lost rent | EUR 800 - 1,200 |
| Property tax (1/12th) | EUR 80 - 150 |
| Home insurance | EUR 15 - 30 |
| Co-ownership charges | EUR 50 - 150 |
| Mortgage (if applicable) | EUR 400 - 800 |
| Total per month | EUR 1,345 - 2,330 |
A single month of vacancy cancels out 1 to 2 months of net yield. Over a 9-year lease, 3 months of vacancy represent a loss of EUR 3,000 to 7,000. Minimising vacancy is therefore a major lever for profitability.
Main causes of vacancy
| Cause | Frequency | Solution |
|---|---|---|
| Rent too high | Very frequent | Market study, adjustment |
| Poorly maintained property | Frequent | Refresh between two tenants |
| Poor listing | Frequent | Professional photos, careful description |
| Bad EPC score | Growing | EPC improvement |
| Low-demand location | Structural | Rent adjustment |
| Bad timing (summer, holidays) | Seasonal | Anticipate the end of lease |
The number one cause is a poorly calibrated rent. A difference of EUR 50 to 100 above market rate can double the time to find a tenant. See our guide to estimate the right rent.
Preventing rental vacancy
Anticipate the tenant’s departure. As soon as the notice is given, start the search. Do not wait for the actual departure to publish the listing. With the sitting tenant’s consent, organise viewings before their departure.
Maintain the property continuously. A freshly refurbished property between two tenants rents faster than one requiring works. Set aside a budget for restoration (painting, professional cleaning, minor repairs).
Optimise the EPC. A poorly rated property rents more slowly and for less. Tenants compare the total cost (rent + charges). A good EPC score is a letting advantage.
Perfect the listing. Quality photos and a precise description attract more candidates. See our guide on writing a good listing.
Reletting quickly
| Action | Impact on timeline |
|---|---|
| Publish on multiple platforms | -2 to -4 weeks |
| Professional photos | -1 to -2 weeks |
| Group viewings | -1 to -2 weeks |
| Online lease (quick signing) | -1 week |
| Rent at market rate | -2 to -4 weeks |
The ideal is to sign the new lease before the former tenant’s departure for a seamless transition with no vacancy. This requires planning ahead: publish the listing 2 months before the end of the lease, organise viewings efficiently and use an online lease to speed up signing.
A rental management software alerts you on lease deadlines and helps you anticipate every step of the reletting.
Frequently asked questions
-
One month of vacancy represents the lost rent plus fixed charges (property tax, insurance, co-ownership charges). For an apartment at EUR 900/month, the real cost is approximately EUR 1,100 - 1,200 per month of vacancy.
-
On average, a property re-lets in 1 to 3 months in Belgium. The duration varies depending on the location, price and condition of the property. In Brussels, demand is strong and vacancy is shorter. In rural areas, it can exceed 3 months.
-
Not directly. However, if the property is involuntarily unoccupied for more than 180 days, a reduction in the property tax may be requested (reduction for unproductive property).
