A clear and professional guide to successfully preparing your application.
When you decide to take the plunge and buy a home and need financing, one of the keys to moving forward quickly is to have your documentation well prepared. A complete, structured and professional file not only avoids delays, but also improves your chances of approval and puts you in a better position with the banks.
At Finzia, we clearly explain what documentation is usually required by financial institutions, depending on your profile.
General documentation (applicable to all profiles)
This information is essential for any mortgage application:
- Valid national identity card or foreign resident identification number
- Marital status and family register (if applicable)
- Latest income tax returns (IRPF)
- Updated employment history report
- Bank statements for the last 3-6 months
- Information about other current loans, debts or guarantees
- Proof of savings/initial contribution (if applicable)
- Deposit or reservation agreement (if already in place)
If you are an employee
- Employment contract
- Last 3 payslips
- Company certificate (in some cases, to confirm length of service or type of contract)
If you are self-employed
- Quarterly and annual VAT and income tax returns (forms 130, 131, 303, 390, etc.)
