Voorbehoud financiering (mortgage contingency) is the single most important clause in your koopakte. It states: "If my mortgage is rejected, I can cancel without penalty." Without it, you risk losing your €20,000-50,000 deposit.
Quick Summary
- • Protects your deposit if the bank rejects your mortgage application
- • Standard deadline: 4-6 weeks from contract signing
- • You must prove good faith effort (apply to 2-3 banks minimum)
- • Never waive this clause unless you have 100% cash or ironclad pre-approval
- • Automatic cancellation if deadline passes without approval
How It Works
When you sign a koopakte with voorbehoud financiering, you have a set period (typically 4-6 weeks) to secure mortgage approval. If any bank rejects you—for any reason—you can cancel the purchase and get your full deposit back.
When Sellers Push Back
In competitive markets, sellers sometimes demand you waive this clause to make your offer more attractive. This is extremely risky. Only consider it if you have mortgage pre-approval for the exact property with a confirmed valuation.
Key Takeaways
- →Never sign a koopakte without this clause—it's your only protection if financing falls through.
- →Apply to multiple banks immediately after signing to meet the deadline.
