When you apply for a mortgage, the lender asks for your recent bank statements — usually the last two to six months of your main current account, and sometimes of your savings. Payslips say what you earn; statements show what you actually do with it. Knowing what an underwriter looks for lets you spot problems before they do.
The six things lenders check
- Income arrives as stated. Your salary or business income on the statements should match your payslips or accounts, every month, from the employer or client you named.
- Regular commitments. Rent, loans, car finance, credit cards, buy-now-pay-later plans, childcare and subscriptions. Lenders add them up to work out what you can afford, and a commitment you did not declare is a red flag.
- Large or unusual deposits. Any big amount that is not your salary will need an explanation, especially for the deposit itself: a gift letter from family, a sale, an inheritance or savings moved from another account.
- Overdrafts and returned payments. Being overdrawn every month, or payments bounced for lack of funds, suggests a tight budget.
- Gambling and payday loans. Frequent betting transactions or short-term loans make many lenders more cautious.
- The deposit is really yours. Lenders must check where the deposit money came from, so they follow it through your statements.
Review your statements before the lender does
Go through the same months you will submit and answer:
- What is my average monthly income, and does it match my payslips?
- What do I pay every month in fixed commitments?
- Which deposits will I need to explain, and do I have the documents?
- Was I overdrawn, and how often?
Convert the statements with StatementEasy and open the Insights tab: it shows income and spending per month, recurring payments with their typical amount, and the large one-off deposits a lender will ask about. You can download that summary as its own spreadsheet to keep with your application notes.
Practical tips
- Plan ahead. The three to six months before you apply are the ones that will be read. Avoid new credit, gambling and unexplained transfers in that time.
- Keep the paper trail for your deposit. Gift letters, sale documents and statements of the account the money came from.
- Cancel what you do not use. Subscriptions count as commitments; find them all first.
- Send complete statements. All pages, as downloaded from your bank. Screenshots of an app are often refused.
- Self-employed? Lenders read business and personal statements together. Keep the two accounts separate and the transfers between them clear.
Common questions
Do lenders really read every transaction?
Many use software that categorises transactions automatically, and an underwriter reviews anything flagged. Assume every line can be seen.
Is one bad month a problem?
Usually not if it is explained — an unexpected bill, a move, a holiday. A pattern over several months matters more.
Can I send a spreadsheet instead of PDFs?
No, lenders want the bank’s statements. The spreadsheet is for your own preparation.
