Understanding mortgages

Buying a home is probably the biggest investment of your life. Understanding how mortgages work is essential to making the best decision.

Types of mortgages

Fixed-rate mortgage

  • Interest doesn’t change throughout the life of the loan
  • Stable and predictable payments
  • Ideal for those who want security

Variable-rate mortgage

  • Interest varies according to the Euribor
  • Payments that can go up or down
  • Historically cheaper in the long term

Mixed mortgage

  • First years at fixed rate
  • Rest of the loan at variable rate
  • Combination of security and flexibility

Typical requirements

Banks usually ask for:

  • Savings: between 20% and 30% of the price (deposit + expenses)
  • Job stability: permanent contract or seniority
  • Sufficient income: the payment should not exceed 30-35% of income
  • Good credit history: no defaults

Associated costs

In addition to the property price, you need to account for:

  • Taxes (ITP or VAT): approximately 10%
  • Notary and registry: 1-2%
  • Agency: €300-500
  • Valuation: €300-400

Negotiation tips

  1. Compare offers from several banks
  2. Negotiate the tie-ins (insurance, direct debit salary)
  3. Review opening and cancellation fees
  4. Consult an independent mortgage advisor
