Applying for a mortgage involves gathering a considerable amount of documents. Arriving at the bank with an incomplete file doesn't just delay the process — it can make you lose the property you want if another buyer moves faster. This guide gives you the complete list, organized by worker type, so you arrive ready on day one.
Why do banks require so many documents?
Banks perform a thorough risk analysis before approving a mortgage. They need to verify three fundamental things: your identity, your repayment capacity (that your income is sufficient and stable), and the viability of the collateral (that the property has real value and no legal issues).
Identity and basic documents (all applicants)

- Valid national ID (cédula de ciudadanía), enlarged copy at 150%
- Updated RUT (Tax Registry)
- Co-debtor or guarantor's ID (if applicable)
- Credit application form (supplied by the bank)
- Authorization for credit bureau consultation (DataCrédito, Transunion)
Documents for formal employees
- Last 3 pay stubs: confirm actual salary received.
- Employment certificate no older than 30 days, including: position, contract type, seniority, and base salary.
- Income tax returns for the last 2 years (if you file). If not, the bank may request a non-filer letter.
- Bank statements for the last 3 months.
The employment certificate is the most critical document. Ensure it explicitly states monthly salary, seniority in years and months, and contract type. Banks return applications if this document is incomplete.
Documents for self-employed workers
- Income tax returns for the last 2 years (certified by a public accountant): the main document to certify income.
- Chamber of Commerce certificate no older than 30 days (if you have a business).
- Bank statements for the last 6 months (double that for employees, because income is more variable).
- Financial statements (balance sheet and income statement for the last 2 years, signed by an accountant).
- Updated RUT with the correct economic activity.
Property documents
- Purchase promise or letter of intent (for used housing) or development enrollment letter (for new housing).
- Certificate of title and encumbrances (certificado de tradición y libertad) no older than 30 days: confirms current ownership and that there are no mortgages, liens, or other encumbrances.
- Approved blueprints and building permit (for new properties or modified ones).
- Property administration clearance certificate (for apartments in residential complexes).
Additional documents for subsidies
If you are applying for a Cajas de Compensación subsidy (Cafam, Colsubsidio, Compensar, Comfenalco, Comfama) or FRECH, add:
- Subsidy assignment letter issued by the Caja de Compensación.
- Affiliation certificate to the Caja de Compensación with a minimum seniority of 1 year.
- Certificate of non-home-ownership (obtained at the Superintendencia de Notariado).
Common mistakes that delay approval
- Expired documents: the employment certificate and title certificate are valid for 30 days. Don't obtain them too early.
- Income inconsistencies: if salary in the employment certificate doesn't match pay stubs or bank statements, the bank will ask for explanations.
- Undeclared debts: the bank consults DataCrédito and will see all your debts. Surprises in the credit report frequently cause denial or reduction of the approved amount.
- Expired national ID: more frequent than you'd think.
Tips to speed up the process
- Pre-organize a digital folder: scan all documents in high resolution and name them clearly. You can send them to the bank in minutes.
- Check your DataCrédito history before applying. You have the right to one free annual check. Verify there are no incorrect negative reports.
- Talk to a mortgage advisor before gathering documents: each bank has slightly different requirements.
