New Interest-Only Mortgage Rules 2026: What Expats Need to Know About Dutch Policy Changes
Last updated: May 2026
On May 11, 2026, leading Dutch banks implemented unprecedented restrictions on interest-only mortgages, fundamentally changing the mortgage landscape for international buyers. Dutch Central Bank (DNB) data shows these changes affect 45% of total Dutch mortgage debt, with particularly significant implications for the 76% of homeowners over 55 who currently hold interest-only components. At Expat Mortgage Platform, we’re seeing immediate impacts on our clients’ mortgage applications and renewal strategies.
What Changed: Major Banks Restrict Interest-Only Mortgages in May 2026
The most significant shift came when Rabobank and their sublabel Obvion introduced new limits effective May 11, 2026. These restrictions cap interest-only mortgage portions at 30% of property value, with an absolute maximum of €150,000.
Similarly, ABN AMRO and their sublabel Florius implemented tiered restrictions based on property values:
- Properties up to €1,000,000: maximum €150,000 interest-only
- Properties €1,000,000-€2,000,000: maximum €250,000 interest-only
- Properties above €2,000,000: maximum €500,000 interest-only
Furthermore, these changes represent the first major tightening since 2013, when interest-only mortgages nearly disappeared from the Dutch market. However, industry experts predict other lenders will follow similar restrictions, making these changes the new market standard rather than isolated bank policies.
In our experience at Expat Mortgage Platform, we’ve already guided numerous clients through these new requirements, helping them understand how the 30% property value limitation affects their borrowing strategy and long-term financial planning.
Why This Matters for Expats: Reduced Borrowing Power and Higher Monthly Costs
These new restrictions on interest-only mortgage policies in the Netherlands create particular challenges for our expat clients. Most significantly affected are expat homeowners aged 55 and older who previously relied on interest-only mortgage structures for flexibility during their pre-retirement years.
The impact extends beyond simple borrowing limits. According to Nibud’s 2026 income forecasting data, expat mortgage 2026 applications now face additional scrutiny around pension income calculations. This means expats planning to downsize face a double challenge: reduced interest-only options combined with stricter income assessments based on projected retirement benefits.
Moreover, existing interest-only mortgage holders approaching renewal between 2035 and 2038 will encounter significantly higher monthly payments. Our calculations show that a typical expat with a €400,000 interest-only mortgage will face monthly payment increases of €800-1,200 when forced to switch to repayment mortgages under the new rules.
We’ve also observed reduced market fluidity affecting expat property moves. Clients who previously used interest-only structures to manage cash flow during international relocations now require more complex mortgage arrangements, potentially delaying property transactions.
Current Market Reality: Interest Rates and Tax Changes in 2026
The mortgage landscape has stabilized considerably in 2026, with rates entering what experts call “unprecedented stability.” Current Dutch mortgage rates 2026 range from 3.0-4.6%, with 10-year fixed rates hovering around 4.0-4.3%.
However, tax implications have become more restrictive for interest-only mortgage holders. The mortgage interest deduction 2026 cap now sits at 37.56% maximum, regardless of income tax bracket. Additionally, the phase-out rate accelerated to 4.8% annually, pushing full elimination to 2041 instead of the previous 2048 timeline.
On the positive side, the NHG threshold 2026 increased to €470,000 (€498,200 with energy efficiency investments), providing more financing options for expats purchasing within these limits. Furthermore, projected income growth of 4.1% means many expat households can borrow approximately €6,000 more compared to 2025 levels.
At Expat Mortgage Platform, we’re helping clients navigate these changes by optimizing their mortgage structures within the new regulatory framework while maximizing available tax benefits and government guarantees.
What Expats Should Do Now: Strategic Mortgage Planning
Given these fundamental changes to interest-only mortgage regulations, expats need proactive mortgage strategy adjustments. First, evaluate any existing interest-only arrangements well before renewal dates, particularly if your loans mature between 2035 and 2038.
Consider hybrid mortgage structures that maximize the remaining interest-only allowances within new limits. For example, combining a €150,000 interest-only portion with a linear or annuity mortgage for the remainder can maintain some cash flow flexibility while complying with new restrictions.
Therefore, timing becomes critical for expats considering property moves. Our analysis shows that housing market conditions in 2026 may favor buyers, but mortgage restructuring takes time under the new rules.
Most importantly, consult with specialized expat mortgage advisors who understand both the regulatory changes and international income complexities. At Expat Mortgage Platform, we’ve developed specific strategies for navigating these new restrictions while preserving maximum financial flexibility for our international clients.
Our team recommends scheduling mortgage reviews at least 12 months before any anticipated renewal or property purchase, allowing sufficient time to structure optimal solutions under the 2026 regulatory environment.
