MORTGAGE APPLICATION
A mortgage lender may ask to see bank statements when assessing an application. They can help evidence income, expenditure and other information relevant to the lender’s affordability and underwriting assessment.

Your home may be repossessed if you do not keep up repayments on your mortgage.
Why do mortgage lenders ask for bank statements?
Requirements vary, but statements may help a lender verify information supplied in the application and understand relevant aspects of the applicant’s finances.
Bank-statement requirements vary between lenders and applications. Being asked for statements does not mean there is necessarily a problem with your application.
What might a mortgage lender look at?
Income
Salary and other income appearing in the account may help support information provided in the application.
Regular commitments
Payments for loans, credit and other commitments may be relevant to affordability.
Household expenditure
A lender may consider expenditure where relevant to its affordability assessment.
Overdrafts and borrowing
Use of an overdraft and other borrowing may form part of the lender’s overall assessment.
Large or unusual transactions
A lender may request further information about transactions it needs to understand.
Deposit funds
Statements may help evidence the availability or source of money being used towards the purchase.
How many months of bank statements do I need for a mortgage?
There is no universal number. Requirements vary by lender, applicant, income type and circumstances. The lender or mortgage adviser can explain what is required for a particular application.
Do lenders check all of my spending?
Lenders assess applications according to their own affordability and underwriting criteria. This does not mean every individual purchase is judged in isolation.
Can bank statements affect a mortgage application?
Information on statements can be relevant where it affects affordability, commitments or information supplied in the application. The significance depends on the circumstances and lender’s criteria.
What if I regularly use my overdraft?
Overdraft use may be considered as part of the overall financial picture. It does not automatically prevent someone obtaining a mortgage.
What about gambling transactions?
Gambling transactions do not create a universal mortgage outcome. Where expenditure is relevant to affordability or raises questions about information supplied in the application, a lender may take it into account or request further information. Treatment varies by lender and circumstances.
What if there is a large payment on my bank statement?
A lender may ask for an explanation or supporting evidence where it needs to understand a transaction. Applicants should provide accurate information rather than attempting to alter their normal financial records for an application.
Do self-employed applicants need bank statements?
Requirements vary. Personal and/or business bank statements may sometimes be requested alongside other evidence.
Do bank statements prove my mortgage deposit?
Statements can form part of source-of-funds evidence, but additional documentation may be required depending on where the deposit came from.
How should I prepare my bank statements for a mortgage application?
Provide the period requested by the lender
Make sure statements are complete and legible
Be ready to explain relevant transactions if asked
Provide supporting evidence where required
Make sure application information is accurate and consistent
Ask your adviser if you are unsure what is required
Can a mortgage adviser help?
An adviser can explain the documentation likely to be required, discuss relevant aspects of the application and deal with lender queries within the scope of their service.
