Mortgage application: the complete list of documents to provide
Putting together a mortgage application is, above all, gathering the right supporting documents. The lender checks three things: who you are, what you earn, and what you're financing. A complete, readable file from the start builds trust and saves days on the agreement in principle.
Here's the complete list of documents needed for a mortgage, organised by block, with the extra documents required depending on your profile. At the end, a simple method to gather all of it without chasing the borrower ten times.
The 4 blocks of a mortgage application
Whatever your situation, a mortgage file always consists of the same broad families of documents. Knowing them lets you prepare everything at once, rather than answering the lender's requests one at a time.
The four blocks are: identity and personal situation, income and liabilities, deposit and bank position, and documents related to the financed property.
Block 1 — Identity and personal situation
These documents establish who the borrowers are and their family situation. They're required for each borrower and co-borrower.
- Valid ID (national ID card or passport)
- Proof of address less than 3 months old (utility or phone bill, rent receipt)
- Marriage or civil-partnership certificate where applicable
- If renting: current lease and latest rent receipts
- If a homeowner: title deed and latest property-tax notice
Block 2 — Income and liabilities
This is the heart of the analysis: the lender assesses repayment capacity and the debt-to-income ratio. The documents differ depending on whether you're an employee or self-employed.
- Last 3 payslips (employees) or last 2-3 sets of accounts (self-employed)
- Last 2 tax assessments
- Employment contract or company-registration extract depending on status
- Proof of other income: rental, pensions, recurring bonuses
- Amortisation schedules for current loans (car, consumer, other property)
If you're an employee
Expected documents cover recent income and its stability: last 3 payslips, December payslip (year-to-date total), last 2 tax assessments and your employment contract. A permanent contract past the probation period reassures the lender.
If you're self-employed or a company director
The lender looks at the consistency of the business: last 2-3 sets of annual accounts, recent tax assessments and a company-registration extract less than 3 months old. A forecast may be requested for a recent business.
Block 3 — Deposit and bank position
The lender wants to understand your day-to-day money management and the origin of your deposit. Well-kept accounts, with no incidents, count as much as the size of the deposit.
- Last 3 statements for all your current accounts
- Proof of savings and deposit: savings accounts, life insurance, etc.
- Proof of the origin of the deposit (savings, gift, sale of an asset)
- Where applicable, employer or assisted-loan agreement
Block 4 — Property documents
These documents describe the property and the structure of the deal. They often arrive a little later in the file, as the project progresses.
- Signed sale agreement (compromis/promesse de vente)
- Proof of deposit and financing plan
- For a new build or works: detailed quotes, construction or off-plan contract
- Property description, floor area, surveys where applicable
Extra documents depending on the profile
Beyond the common base, some situations call for specific documents. Anticipating them avoids a mid-file request from the lender.
Co-borrower
Each co-borrower provides their full set of identity, income and bank documents. A two-person application means two complete sets of supporting documents.
Remortgage or bridging loan
Add the amortisation schedules of the loans being refinanced and, for a bridging loan, the valuation or sale mandate of the current property. If the operation is actually a debt consolidation — folding several existing loans into one — the list of documents runs longer than it looks: see our dedicated guide to debt consolidation documents, which covers the specific block required for each loan being paid off.
Gathering all these documents without chasing the borrower ten times
The hard part isn't knowing the list: it's collecting it. By email, documents arrive one at a time, in the wrong format, and it's on the broker to chase again and again — often discovering a missing document the day before the agreement.
The effective method: send a clear checklist via a secure portal. The borrower sees exactly what to provide, uploads their documents with no account to create, and automatic reminders handle the rest until the file is complete. You get a clean file, ready for the lender. These ID documents and bank statements are among the most sensitive personal data you handle: the GDPR principles that apply to collecting them (legal basis, retention period, security) are covered in our dedicated article on GDPR and client document collection.
Frequently asked questions
- How many payslips do I need to provide?
- Usually the last 3 payslips, plus the December one that summarises the year-to-date total. Lenders also ask for the last 2 tax assessments.
- What documents for a self-employed borrower?
- The last 2-3 sets of annual accounts, recent tax assessments and a company-registration extract less than 3 months old. A forecast may be requested if the business is recent.
- Do co-borrowers provide the same documents?
- Yes. Each co-borrower provides their full set of identity, income and bank documents.
- How do I avoid last-minute missing documents?
- By sending the borrower a tracked checklist rather than a list by email: they see what's left to provide, upload to a secure portal, and automatic reminders prevent omissions.
