Short answer
More equity reduces the loan and rate risk but ties up liquidity. A robust plan separates transaction costs, purchase-price contribution and emergency reserve. There is no universal ideal percentage.
Important variables
- Price and case-specific acquisition cost
- Loan terms at different leverage levels
- Remaining liquidity reserve
- Alternative use of capital

Worked example
€100,000 available does not automatically mean €100,000 down payment. If €45,000 is needed for costs and €20,000 for reserves, €35,000 remains for price equity.
Break-even: What changes the result?
Higher mortgage rates increase the guaranteed benefit of more equity. Large foreseeable renovations increase the value of a larger reserve.
Common mistakes
- Using all available cash
- Treating transaction cost as property value
- Testing only one finance structure
