Investing in new vs old for rental in Belgium
Should you buy new-build or old property for rental investment in Belgium? Price, yield, taxation, maintenance: complete analysis with 2026 data.
New vs old: the 2026 figures
The question divides investors: should you pay more for new-build, or maximise yield with old property? Belgian market data for 2025-2026 shed light on this debate.
| Criterion | New-build | Old property |
|---|---|---|
| Average price/m2 | 3,200 EUR | 2,250 EUR |
| Average rent 2 bed. | 880 EUR | 760 EUR |
| Gross yield | 3.2% | 4.5% |
| Average EPC | A-B | D-F |
| Annual maintenance | 0.3% of price | 1.5% of price |
| Vacancy | 2% | 5% |
The new-build premium reaches 42% on average. New-build rents are 15 to 20% higher, but this gap does not compensate for the price difference. Old property gross yield remains over a point higher.
Over 15 to 20 years, new-build catches up thanks to much lower maintenance costs and better value retention. The choice depends on your investment horizon.
The advantages of new-build
EPC and rental attractiveness
A new-build property in Belgium consistently achieves EPC A or B. This is a strong argument on the rental market:
- Rents 15 to 20% higher than an equivalent old property
- Reduced energy costs for the tenant (selling point)
- Compliance with future energy standards (no risk of devaluation)
- In Brussels, no rental deposit limitation (reserved for EPC E-G)
Minimal maintenance costs
In the first 10 years, maintenance costs for new-build are virtually nil:
- Ten-year structural warranty
- Two-year equipment warranty
- No renovation work needed
Over 10 years, the maintenance saving can reach 15,000 to 25,000 EUR compared with old property.
Reduced vacancy
New-build properties let faster and at higher rents. The average vacancy rate is 2% vs 5% for old property. Tenants also tend to be more stable (higher income profile, longer leases).
The advantages of old property
Higher gross yield
The clinching argument for old property: a gross yield of 4.5% on average, 1.3 points higher than new-build. For an investor seeking immediate cash flow, this is decisive.
Accessible purchase price
For the same budget, old property allows you to buy a larger or better-located property. In Liege, 200,000 EUR buys a 2-bedroom flat in the city centre in old stock, vs a studio on the outskirts in new-build.
Capital gain potential through renovation
A well-renovated old property can generate significant immediate capital gains. Energy renovation (insulation, boiler, windows) improves the EPC by 2 to 3 classes, increasing both property value and potential rent.
Do not underestimate renovation costs. Moving from EPC E to EPC B costs on average 30,000 to 60,000 EUR depending on property size. Factor this amount into your net yield calculation.
Premium location
Old properties are often better located (historic city centres, established neighbourhoods) as available land for new-build is increasingly found on the outskirts.
Taxation compared
Belgian taxation treats new-build and old property differently:
| Tax item | New-build | Old property |
|---|---|---|
| Purchase | 21% VAT | Registration fees 12.5% (WAL/BXL) or 3% (FL) |
| Cadastral income | Recent base (higher) | Older base (often lower) |
| Property tax | On higher CI | On lower CI |
| Renovation | 6% VAT (> 10 years) | 6% VAT (> 10 years) |
In Wallonia and Brussels, old property benefits from registration fees (12.5%) lower than new-build VAT (21%). In Flanders, the 3% rate for sole residences makes old property even more competitive.
One often-overlooked point: the cadastral income of new-build is generally higher than that of an equivalent old property, which increases both property tax and the tax base. A professional lease helps optimise the allocation of tax-related charges.
Verdict: old for yield, new for wealth-building
| Profile | Recommended choice | Reason |
|---|---|---|
| Immediate cash flow | Old property | Higher gross yield |
| Long-term wealth | New-build | Lower charges, better value retention |
| Limited budget | Old property | Lower entry ticket |
| First rental | New-build | No works, tenant quickly |
| Hands-on investor | Old to renovate | Capital gain through renovation |
The ideal for many investors is a recent old property (2000-2015): intermediate price, decent EPC (B-C), moderate charges and still attractive yield.
To identify the best opportunities, cross-reference this analysis with our ranking of the most profitable cities and our comparison Flanders vs Wallonia vs Brussels.
Comparison based on average sale prices for new and old properties (Statbel Q4 2025), average rents by property type and EPC rating (Immoweb), and estimated charges over 10 years. New-build includes flats delivered in 2024-2025. Old property covers buildings constructed before 2010.
Frequently asked questions
-
No, in gross yield terms. Old property offers an average gross yield of 4.5% vs 3.2% for new-build. The new-build premium (42% on average) is not offset by proportionally higher rents. New-build catches up on maintenance costs and capital gains.
-
New-build offers excellent EPC (A or B), near-zero maintenance costs in the first 10 years, 21% VAT instead of registration fees, and a ten-year structural warranty. It also attracts premium tenants willing to pay higher rent.
-
The main risk is renovation costs: energy upgrade, electrical rewiring, roof replacement. Budget 10 to 20% of the purchase price for an old property in good condition, more for an energy-inefficient one.
