What lenders look for in bank statements

When a lender asks for 12 or 24 months of statements, an underwriter reads them line by line. This guide lists what they are looking for, why each item matters, and what you can do about it before you apply.

Consistent deposits

The first thing an underwriter does is total the deposits for each month and look at the row of twelve or twenty-four numbers. Steady is good. Lumpy is fine if it is explainable: a landscaper with quiet winters, a consultant paid on project milestones. What raises questions is a pattern that does not fit the business you described, or a few months that carry most of the year. Expect to explain any month that is less than half, or more than double, your average.

Large deposits and source letters

A single deposit far above your normal month is set aside until you show where it came from. Programs differ on the threshold; a common one is 150% of your average monthly deposits, others use 100%, 200% or a dollar figure. For each one you will write a short letter of explanation and attach the document that backs it: a signed contract or invoice for a big client payment, a closing statement for a property sale, a bill of sale for a vehicle, a gift letter for money from family. Without the document the deposit is excluded from income; with it, many programs count it. Write the letters before you apply, while you still remember what the deposit was.

NSF and overdraft fees

Non-sufficient-funds and overdraft fees say the account ran dry. Underwriters count them over the last twelve months, and many programs allow none, or two or three at most. If you have any, be ready with a one-line explanation each, and stop them now: twelve clean months from today is the fix.

Transfers between your own accounts

Money moved from savings or from another checking account shows up as a deposit but is not income, and the underwriter will subtract it. That is normal and not a problem, as long as the transfers are recognisable. Trouble starts when a transfer in looks like a client payment, or when money circulates between accounts in a way that inflates deposits on the statements you submitted. If you keep a business account and sweep money to a personal one, submit the account the income first lands in.

Cash deposits

Cash cannot be traced to a customer, so many programs cap how much cash they count or exclude it entirely. A cash-heavy business (a restaurant, a salon, a market stall) should ask about this before choosing a program, and should look at how much of the year's deposits are cash.

Declining income

With 24 months of statements, the underwriter compares the two years. If the second is well below the first, most programs use the lower year, or the average, and some ask for a written explanation of why income fell and whether it has recovered. With 12 months, a second half well below the first half gets the same question. A rising trend is not rewarded in the same way, so if your business has grown, the most recent twelve months may give you a better figure than twenty-four.

Reserves and the lowest balance

Lenders want to see money left over after closing: several months of the new mortgage payment, sitting in accounts you can show. The running balance on your statements tells them how close to zero the account gets and when. A healthy income with a balance that touches $200 on the 28th of every month reads differently from the same income with $15,000 always in the account. Statements for savings, brokerage and retirement accounts count toward reserves and are worth submitting even when they are not needed for income.

Missing pages and statements that do not add up

Every statement must be complete: every page, and every month in the period with no gaps. Underwriters check that a statement's transactions carry its opening balance to its closing balance; when they do not, a page is missing or something was removed, and the file goes back to you. Download the bank's own PDF for each month rather than printing screens, and check the page count against the number printed on the statement.

How to prepare

• Download every statement for the period as the bank's own PDF, all pages. The converter reads them and tells you whether each statement adds up.
• Run the loan calculator on them and read the flags. Each flag is a question you can answer now instead of later.
• Write a letter for each large deposit and gather the backing document.
• Write a line for each NSF or overdraft fee, and make sure there are none from now on.
• Gather statements for the accounts that hold your reserves.
• Have proof the business has existed for at least two years: a licence, a CPA letter, or your state's business registry.

For how the income figure itself is computed, including the expense factor and a worked example, see how bank-statement loans work and the calculator page. The figures the tool shows are estimates for your own preparation, not a lender's decision; every program sets its own rules.
