Mortgage rates in 2026: stabilisation after the storm
After the shock of 2022-2023 (from 1.5% to 3.5% in 18 months), Belgian mortgage rates are stabilising around 3.0-3.2% for a 20-year fixed loan in Q1 2026.
| Loan type | Average rate Q1 2026 | Best rate observed |
|---|---|---|
| Fixed 20 years | 3.1% | 2.7% |
| Fixed 25 years | 3.2% | 2.9% |
| Variable (1/1/1) | 2.5% | 2.2% |
| Fixed 10 years | 2.8% | 2.5% |
This stabilisation has revived the purchase market: the number of mortgage loans granted increased by 12% in 2025 compared to 2024 (NBB). But prices remain high and lending conditions strict (minimum 20% deposit, debt-to-income ratio < 50%).
With a rate of 3.1% instead of 1.5%, the monthly repayment on a EUR 200,000 loan over 20 years goes from EUR 965 to EUR 1,123: +EUR 158/month.
ECB policy: cautious status quo
The European Central Bank made 3 rate cuts in 2025 (from 4.0% to 3.0%) but signalled a pause for the first half of 2026. The reasons:
- Eurozone inflation at 2.3% (above the 2% target)
- Resilient labour market
- Geopolitical risks (trade tensions)
Analysts anticipate an additional cut of 0.25 pp in the second half of 2026, which would bring Belgian mortgage rates to around 2.8% by end 2026. For property investors, this is a positive signal but not a return to the rock-bottom rates of 2020-2021.
Buy vs rent: the calculation in 2026
The choice between buying and renting depends on the duration of stay, location and financial profile. Here is a comparison for a EUR 250,000 property:
| Parameter | Buying | Renting |
|---|---|---|
| Monthly cost | EUR 1,250 (20-year loan, 3.1%) | EUR 850 (average 2-bed. rent) |
| Upfront costs | ~EUR 30,000 (notary + duties) | EUR 2,550 (3-month guarantee) |
| Tax benefit | Interest deduction (Flanders only) | None |
| Break-even point | 5-7 years (excluding capital gains) | Always cheaper if < 5 years |
In Brussels, the high registration duties (12.5%) extend the break-even point to 7 years. In Flanders (3% for first purchase), buying becomes profitable from 3-4 years. Consult our Brussels vs Liege vs Namur comparison for investors.
Impact for property investors
Rates at 3% change the equation for property investment:
Yield vs cost of credit
- Average gross yield: 4.3% (Statbel Q1 2026)
- Average cost of credit: 3.1%
- Spread: 1.2 pp (compared to 3 pp in 2020)
The spread has narrowed but remains positive. Leveraged property investment remains profitable provided you:
- Focus on high-yield properties (Wallonia, small units)
- Contribute a minimum of 30% equity to reduce monthly repayments
- Target rents above the net monthly repayment (positive cash flow)
Even with rates at 3%, leverage remains the main attraction of property investment: you invest EUR 60,000 of equity for a EUR 200,000 property. The return on equity is 10-14%, not 4.3%.
Consequences on the rental market
The stabilisation of rates has contradictory effects on the rental market:
Downward effects on rental demand:
- First-time buyers are returning to the purchase market
- More predictable rates reassure borrowers
Upward effects on rental demand:
- Purchase prices remain high (20% deposit difficult for many)
- Banking criteria have tightened (debt-to-income ratio)
- Professional mobility favours flexible renting
The net balance is still-strong rental demand: +4% new leases signed in 2025 vs 2024. For landlords, this means low vacancy rates and maintained negotiating power. Digital rental management allows you to efficiently handle this demand.
Forecasts 2026-2027
| Indicator | H2 2026 forecast | 2027 forecast |
|---|---|---|
| Fixed 20-year rate | 2.8-3.0% | 2.5-2.8% |
| Property prices | +1 to 2% | +2 to 3% |
| Rents | +2 to 3% | +2 to 3% |
| Average gross yield | 4.2-4.4% | 4.3-4.5% |
Rates should continue to decline slowly, supporting the purchase market without draining the rental market. For investors, 2026 remains a window of opportunity: prices have not yet caught up with the rate decline, and rental yields are holding.

It depends on the intended duration of stay and the city. In Brussels, renting remains more advantageous for stays under 7 years (high notary fees). In Wallonia, buying becomes profitable from 4 years thanks to lower prices and reduced registration duties.
